	What is the cause of an A.CC Alarm? Posted Date: 08/27/2004 Answer: When using the DD Motor's single-turn absolute encoder as absolute with Sigma II application modules, e.g. MP940, NS600, etc., Pn205 in the Sigma II Renewal amplifier must be set to 0. The application module reads Pn205 at power on, if Pn205 is not set to 0, an A.CC alarm will be generated. For more information on Alarm Codes, please see FAQ MNEN-5CJMGY.

	What is speed feedback compensation and when should it be used? Posted Date: 07/13/2004 Answer: Speed feedback compensation is typically applied when there is mechanical resonance in the system and the speed loop gain cannot be raised to achieve good response, such as shortened settling time in positioning. It allows the increase of speed reference gain with the speed feedback gain kept low by adjusting the speed feedback compensation value. Because the speed feedback gain is low, there is no vibration added to the resonance part of the machine, and good response is achieved due to the higher speed reference gain. The speed feedback compensation loop uses the speed feedback as the input. Using a proprietary algorithm, this signal is filtered to reduce the effect of disturbance and phase-lag compensation. The output is called the compensated feedback speed. This output, rather than the normal speed feedback signal may be selected via Pn110.1 for use in the speed control loop. Speed feedback compensation level, parameter Pn111, adjusts the gain of the speed compensation loop. Please note that with speed feedback compensation enabled, disturbance response is degraded because speed feedback gain is reduced. Also, the inertia ratio in Pn103 must be correctly set for the speed feedback compensation to function properly. Refer to section 6.2.6 in the Sigma II Servo System User's Manual for adjustment procedure.

	What is an A.E7 alarm and how is it cleared? Posted Date: 07/13/2004 Answer: The A.E7 is an alarm from the Sigma2 (SGDH-xxyE) Servopack that is missing an option card such as an MP940 or NS300 If an amplifier previously had an option card attached, and it is missing at power up, this alarm will occur and persist until the following is performed. Using a Hand Operator or the Built in Operator on the Servopack, the proper procedure is as follows: 1) Execute an "Initialize Parameters to Factory Default" Operation :Fn005 (Section 7.2.9 in Sigma2 manual) 2) Execute an "Alarm History Trace Back Clear" Operation: Fn006 (Section 7.2.5 in Sigma2 manual) 3) Execute an "Option Unit Detection Reset" Operation: Fn014 (Section 7.2.13 in Sigma2 manual) Keywords: AE7, error Product Group/Line: Servo Products, SGDH Sigma II Topic/Sub Topic: Ask a Technical Question, Alarm, Troubleshooting Document Number: DZIK-5HV62J Published Date: 07/13/2004 Share \| Rate Rate this article :	07/13/2004
	What is an A.E5 alarm? Posted Date: 01/22/2002 Answer: An A.E5 (AE5) alarm is a Mechatrolink Synchronization Error between an MP920 or MP930 controller (using SVB modules) and an NS-100. Every mechatrolink communications cycle, the controller increments Watch Dog Timer data (WDT). If the expected data does not match with the data in the NS-100 module, then it is known that the transmission packet also did not get written to/from local register memory (hence the node did not get updated with new deterministic data). Since this is a deterministic control system and data must be transfered, this will flag an A.E5 alarm and it will display on the SGDH LED display. To reset this alarm, the controller must perform the alarm clear sequence TWICE.

	What is an A.09 alarm? Posted Date: 12/22/2011 Answer: An A.09 alarm occurs for SGDH servo amplifiers modified with the Y213 modification when the maximum encoder output frequency is exceeded (Y213 modification applies to a linear motor application). The maximum frequency is 12.8MHz. The frequency is calculated at power-up based on the motor peak speed (Pn384), the linear scale pitch (Pn280), and the PG dividing ratio (Pn281). To reduce the output frequency, either decrease the motor peak speed or decrease the PG dividing ratio. Un010 will display the setting limit at which the frequency will not exceed the maximum (12.8MHz) for either the motor peak speed or the PG dividing ratio. The limit value can by chosen by parameter Pn080.3.

	What could cause an motor to run away when it is enabled (/S-ON goes low)? Posted Date: 07/13/2004 Answer: If the motor is running away, the amplifier must be getting a command from somewhere to run the motor. Typically this occurs when the host controller sends the amplifier a pulse train to the amplifier BEFORE the servo is initialized. This causes a build-up of position error, and when the amp is initialized, the motor tries to catch up. One option to eliminate the timing issue between controller and amplifier is to "mask on" the /S-ON input. The user can do this by changing Pn50A.2 to 7. After cycling control power, the amp is enabled and ready to run as soon as main power is applied.

	What are the minimum parameters required to start-up a Sigma II SGDH type servo amplifier for use with a linear motor? Posted Date: 07/25/2005 Answer: Pn000.1 Control Method Selection Set the amplifier to the correct control method (force control, speed control, position control, etc.) Note: Set Pn000.1=2 for force control Pn280 Linear Scale Pitch [microns] Set the linear scale pitch parameter to the scale pitch (i.e. grating pitch or signal period) of the linear encoder. The linear encoder must output a 1Vpp analog sin/cos waveform. The default setting of Pn280 is 0. Alarm A.08 (linear encoder scale pitch setting error) will occur at power-up if this parameter is left at setting 0. Pn281 Encoder Output Resolution [Pulse/Scale Pitch (Pn280)] - Force/Speed Control This parameter is used to scale the encoder output resolution from the servo amplifier. The factory setting is 20; therefore, for a linear encoder with a scale pitch of 40 micron (Pn280=40), the encoder output resolution is 20 pulses (Pn281) divided by 40 micron (Pn280), or 1 pulse per 2 microns. Pn202 Electronic Gear Ratio (Numerator) - Position Control The Electronic Gear Ratio is used to scale the input position reference. See the following FAQ: How are the Electronic Gear Ratio parameters, Pn202 and Pn203, set for linear motors? Pn203 Electronic Gear Ratio (Denominator) - Position Control The Electron Gear Ratio is used to scale the input position reference. See the following FAQ: How are the Electronic Gear Ratio parameters, Pn202 and Pn203, set for linear motors? Pn483 Forward Thrust Limit [%] To prevent danger during motor setup, the factory setting of the forward force limit is set low to 30%. Verify that the linear motor is working properly before increasing this value. Pn484 Reverse Thrust Limit To prevent danger during motor setup, the factory setting of the reverse force limit is set low to 30%. Verify that the linear motor is working properly before increasing this value. Pn50A.3 P-OT Input Signal Mapping The positive overtravel input is factory set to prohibit forward motion. Connect a limit switch to the P-OT input to prevent forward motion beyond the allowable range. The P-OT input can also be disabled to always allow forward motion by setting Pn50A.3 equal to 8. Pn50B.0 N-OT Input Signal Mapping The negative overtravel input is factory set to prohibit reverse motion. Connect a limit switch to the N-OT input to prevent reverse motion beyond the allowable range. The N-OT input can also be disabled to always allow reverse motion by setting Pn50B.0 equal to 8.

	What are some remedies to an A.C9 (Encoder Communications) alarm? Posted Date: 07/13/2004 Answer: The Sigma II User manual points out how to start troubleshooting. The most likely causes to A.C9 (AC9) alarms are: A.C9 Alarm Causes: A) Wiring issue causing electrical noise to enter the system B) Defective encoder board on the motor C) Defective amplifier A) Wiring issue causing electrical noise to enter the system If the system is faulting out on an A.C9 alarm while the servo is operating, the system wiring should be reviewed. The most common source of this error is due to poor installation. The overall system ground should be first checked and verified against recommended installation procedures in the manual. In the event that this alarm does occur, if it is random, the encoder cable and its installation should be examined next. 1) Check to insure the cable is wired according to the Yaskawa Manual 2) SGMG, SGMGH, SGMS, SGMSH encoder cables should be shielded on both ends of the cable 3) When dealing with longer encoder lengths, its important that larger size wire is used for the encoder +5VDC power and common (to prevent IR drop). See Yaskawa manual for special cable to suit this. Assuming the encoder cable is electrically o.k., consider the following: 1) Are the encoder cable and power cable running the same conduit? If yes, separate them. 2) If the power and encoder cables are already running at least 10" apart, or the encoder cable must share conduit with other signal lines, try installing a ferrite core (YEA p/n ESD-SR25) at each end of the encoder cable. This will effectively increase the high frequency impedence, improving the system noise immunity. 3) If the amplifier is a 400V SGDH, and is 6kw and higher, a separate isolated 24VDC control power supply is required for each unit. The ferrite core clamps easily on to the cable and dampens high frequency noise which can cause the A.C9 alarm. This is a low cost (less than $10) solution that often does the trick.

	What are some potential causes of an A.E2 alarm? Posted Date: 06/24/2013 Answer: An A.E2 alarm is a watchdog timer alarm, caused by either an MP940 processor time-out or an MP940-SGDH communications synchronization error. Below are some remedies. 1. Excessive system noise - Be sure that the MP940 is grounded to the SGDH (MP940 FG connection on power connector to the SGDH screw terminal on the front side of heat sink with a 16awg short ground wire), and the SGDH is connected directly to the field ground ground bar in the cabinet. Verify that the SGDH is properly grounded. Verify that the subpanel / ground terminal is properly grounded. Make sure that the machine is properly grounded to a sufficient building ground. 2. SGDH Comm Synch Error (Insufficient 24VDC power or bad wire connection) 1) Control power on SGDH and MP940 must power ON within 3 sec of each other 2) Check Dual Port Ram connection between SGDH and MP940 3) Check the 24VDC power supply capacity (if it dips below 21VDC for the unit will automatically watchdog trip as a safety precaution and generate an A.E2 alarm to indicate to user that there is a power supply issue). If the error occurs at the same point in the program all the time, chances are that the program is controlling an output point that draws more current than the power supply is capable of. 4) Verify that all terminal screws that bond wires are securly tightened, sometimes an intermittent connection in the power supply can be caused by loose wires after shipping or moving a machine (vibration of the machine may also cause screws to loosen). 3. MP940 Processor Time-Out - Typically caused when actual H or L scan 'time' exceeds H or L scan 'setting' respectively. The H scan will deterministically execute the entire H program/drawing and sub programs/drawings every H scan setting time cycle. Higher priority background tasks will interrupt the execution, but the H execution must occur in its entirety within the H scan setting. Otherwise, an error will occur. Any remaining time is left over to perform lower priority tasks. Likewise, the L scan will also deterministically execute the entire L program/drawing and sub programs/drawings every L scan setting time cycle. Higher priority tasks will interrupt its execution (such as the H scan), but the L execution must occur within the L scan setting. Otherwise, an error will occur. Hence, if too much time is spent in the H scan, the L scan will be starved of time! As a program grows in size during development, and if this error occurs, most commonly the H scan time will need to be increased. In MW+, it will be necessary to perform a full compile/download for the new values to take effect and maintain after a power cycle. Troubleshooting a Processor time-out - Verify that mProgram_HighScan_Current (SW00005, units of ms/100) and mProgram_HighScan_Maximum (SW00006, units of ms/100) does not exceed the High Scan setting (an MP940 Property attribute in MW+). Note that due to programming differences, various sections of code may not be run under certain conditions. Therefore, it will be necessary to test all conditions so that the maximum scan value can be determined. Example: If mProgram_HighScan_Maximum starts to exceed 70 (0.7 ms) when the high scan setting is 1msec, it would be advisable to increase the high scan setting to 2msec or more as needed. 1) If that does not work, verify that mProgram_LowScan_Current (SW00011, units of ms/100) and mProgram_LowScan_Maximum (SW00012, units of ms/100) do not exceeded the Low scan setting). 2) Another method is prevention. Place critical tasks under high scan setting programs or drawings, and non-critical tasks under low scan programs or drawings. This logical separation also lends itself to good programming practices.

	What are some potential causes of an A.84 Alarm? Posted Date: 06/30/2008 Answer: An A.84 (A84) alarm is an encoder data error alarm. This alarm is valid for both absolute and incremental encoders, and its meaning depends on the type of encoder. Most common application issues that cause an A.84 alarm are: - Excessive Mechanical Vibration - Excessive Electrical Noise If efforts to reduce the above causes do not eliminate the A.84 Alarm, Contact Yaskawa Technical Support for further assistance at 1-800-927-5292, then press 3 for Servo Products. Detailed Information: 12 bit Absolute Encoder This indicates that the absolute encoder data is abnormal. If this alarm appears at power on, the absolute encoder is malfunctioning and replacement may be necessary. If this alarm appears during motor operation, it could be caused by external electrical noise. In this case, check and correct wiring around the encoder (grounding of servo motor, separation of encoder and power cables, insertion of toroidal cores on cables, etc.) - to reduce noise. Incremental Encoder This indicates that data in the encoder is abnormal. If this alarm appears either during operation or at power on (intermittently or static), most commonly system vibration should be examined. Excessive vibration (exceeding motor specifications) (See FAQ # MTN-5XTTDJ) can cause high vibration forces at the cantilevered encoder end (G-forces generated by vibration cause an A.84 alarm if they exceed the motors rated spec). Remedies include: Decrease acceleration values, implement S-Curve acceleration, check the mounting face accuracy and alignment, check the coupling alignment. If alarm persists, permanent damage to encoder may have occurred and motor replacement may be required.

	What are some of the potential causes of an A.80 Alarm? Posted Date: 04/12/2006 Answer: An A.80 (A80) alarm is most often caused by external noise injection into the position feedback system (encoder or encoder cable). For a Sigma I system, this alarm occurs when there is more than 2 counts drift between the actual and expected pulse count at the positive rise of the U-Phase Hall Feedback (amplifier expects count to increase by encoder resolution per motor commutation cycle). For a Sigma II system, this alarm occurs when there is more than 2 counts drift between the actual and expected pulse count at the positive rise of the C-Phase Pulse Feedback (amplifier expects count to increase by encoder resolution per motor revolution). If the alarm is generated at power supply on, either the encoder is wired incorrectly or the servo amplifier should be replaced. If the alarm is generated at run time, noise is most likely the cause, and the following should be checked: 1) If encoder cable distance is long, check to insure that the proper wire gauge is used according to manual spec. 2) Verify the encoder cable construction according to manual spec. 3) Check to insure the encoder cable is not pinched. 4) Check to verify that the Amplifier is properly grounded to the panel field ground according to the manual spec (mounted to metal panel, and proper field ground wire used). 5) Noise entry into the system can also be reduced by using a Ferrite Core on the encoder cable - ZCAT1325-0530A, EMI/RFI clamp filter by TDK, try one or more loops of encoder wire. 6) Check that the system is not subject to excessive vibration impact *Most common fixes Product Group/Line: Servo Products, SGDH Sigma II Topic/Sub Topic: Ask a Technical Question, Alarm, Troubleshooting, Wiring Document Number: MNEN-5CJMKG Published Date: 04/12/2006 Share \| Rate Rate this article :	04/12/2006
	What are potential implications of using an Electro-Mechanical Relay or Switching Power Supply in conjunction with a Sigma II Servo System to enable the motor? Can A.C9 and A.E2 alarms be symptoms? Posted Date: 07/13/2004 Answer: Sigma II Servo Systems (SGDH amplifier) require a 24VDC input to enable the motor. It has been observed that in many cases, an Electro- Mechanical Relay or Contactor is utilized as a Master Control Relay to feed this 24VDC signal to the amplifier and perhaps turn on other devices in the control panel at the same time. In some cases, an A.C9 (Encoder Communications) alarm occurs as soon as the relay is engaged. Assuming the wiring for the encoder and grounding of the amplifier have been done properly, the cause is noise generated from the Electro-Mechanical Relay. Here are some remedies: 1) When using a DC relay, install a "fly wheel diode" across the relay coil. When using an AC relay (or contactor,) use a surge suppression device. This will reduce the potential for chattering, which in turn damps the noise. 2) Mount the relay as far as possible from the Servo Amplifier in the panel. 3) Route encoder cables away from the relay. 4) Install a ferrite core (Yaskawa #ESD-SR25) at the SGDH end of the encoder cable in the panel. 5) Consider using a Solid State switching device instead of an Electro-Mechanical one. If an MP940 is used in conjunction with Sigma II amplifier, an A.E2 alarm may occur. Assuming the cause is not MP940 processor time-out or MP940-SGDH synchronization error, the cause can be noise generated from the Electro-Mechanical relays. The same remedies mentioned above should prove helpful. Switching Power Supplies are also noise-generating devices that could potentially cause an A.C9 (Encoder Communications) alarm. Here are some remedies: 1) Mount the power supply as far as possible from servo amplifier. 2) Route encoder cables away from the power supply. 3) Install a ferrite core (Yaskawa #ESD-SR25) at the SGDH side of the encoder cable. 4) Consider using a linear power supply instead of a switching model.

	On a linear motor x-x'-y gantry system, what is the best method to control the two x-axes? Posted Date: 06/06/2003 Answer: The preferred method is to set-up a master/slave relationship using two axes of a motion controller. The motion controller must monitor the linear encoder feedback from both the x and x'. The x' axis must track the position of the x axis. Another alternative is to set-up a master/slave relationship using only one axis of a motion controller. The motion controller would monitor the linear encoder feedback from the x axis and command the x' axis. The x' axis would follow the encoder output directly from the x axis encoder output. Caution should be taken when implementing this method, since each amplifier operates in a different control method and different loop updates may exist. The following example lists the necessary SGDH amplifier parameter settings for a linear motor master/slave application (assuming a linear encoder grating pitch of 20 microns). Master Axis Parameter Settings: Pn000.1=2 Sets amplifier in Force Control. Pn280=20 Linear encoder grating pitch is 20 micron. Pn281=20 Sets encoder output resolution to 20 micron per 20 pulses (or 1 micron per 1 pulse). Slave Axis Parameter Settings: Pn000.1=1 Sets amplifier in Position Mode. Pn280=20 Linear encoder grating pitch is 20 micron. Pn202=256 Electron gear ratio numerator. Pn203=20 Electronic gear ratio denominator. The electronic gear ratio is used to scale the postion command input.

	Is upgrading from Sigma to Sigma II the best option? Posted Date: 04/13/2006 Answer: There are generally three service choices available to existing users of Sigma I: repair, replace, or upgrade to the latest technology. Yaskawa Customer Service will be happy to provide price and current availability for any or all three of the above options. It is only important to have a complete description of existing P/N numbers that require servicing (Example: Motor P/N# SGM-01U3B4L and Amp P/N# SGDA-01AS). Custom servo systems have part numbers that typically end with a special code, such as SGM-01U3B-Y22 or SGDA-01AS-Y13. See the document below titled Service Options for Customized Servos which will help determine the best course of action. The Upgrade Option: Yaskawa's latest generation products (Sigma II servo systems) closely parallel the previous product offering and are designed to provide an option for upgrade. Generally, these upgrades install in the same mounting locations, have similar wiring arrangements, and subsequently run the machine with performance equal to or better than the previous system. However, good planning is always a prerequisite to a successful upgrade. To decide if upgrading is the best option, read the attached summary of the upgrade process for summary comparisons of mounting, wiring, and performance. For any additional price and availability information required for the decision to upgrade, use the Part Number Converter utility (Sigma I to Sigma II) and Yaskawa's customer service will be able to provide those estimates as an alternative to repair or replace. To simplify the process, these summary documents and utilities are classified by the particular Sigma products being replaced. For determining price and availability for an upgrade, both the motor and amp P/N#s are required. What's Next? If upgrading is chosen as the best option, a more detailed description of the upgrade process is available in a subsequent FAQ in this database titled "What steps are required to upgrade Sigma products to Sigma II?".

	Is there a wiring example of an MP940 following a Sigma II SGDH servo master? Posted Date: 07/13/2004 Answer: Yes. Attached Below is an example wiring of a Sigma II SGDH servo system as a master, wired to the external encoder input of the MP940 system. In this case the SGDH motors encoder is output on the 1CN connector as simulated encoder. The Encoder Output resolution from the SGDH can be changed or divided out by adjusting the PG Dividing Ration Parameter (Pn201). For more information on wiring connections and wiring techniques, please refer to the Sigma II Users manual and the attached MP940 I/O connection diagram.
