	How do I prevent alarm A.E02 (also seen as 0E02h, 0E02, E02, E02h)? Posted Date: 01/05/2016 Answer: A.E02 (also seen as 0E02h, 0E02, E02, E02h) can be caused by setting values into objects after setting object 2700h = 1 (User Parameter Configuration) and before object 2700h returns to 0. The proper procedure for using object 2700h is (as described in the SERVOPACK EtherCAT CoE Network Module User's Manual: 1. Change FSA (Device Control) state to "Switch on Disabled." 2. Set new paramter setting value (e.g. object 2701h). 3. Set object 2700h to 1 for activiting the "new" user settings. 4. When processing is completed, the value of object 2700h is reset to 0. Do not write to any objects through SDO at until object 2700h is read back as 0. If the above procedure is followed. A.E02 will not occur for that reason. If A.E02 continues to occur, contact Technical Support.

	How do I prevent A.95A from occurring on the SERVOPACKs when using the MPiec controller? Posted Date: 01/05/2016 Answer: There are numerous conditions that can cause A.95A. Most of those conditions are handled by the MPiec controller to prevent A.95A occurrences. However, some of these conditions cannot be handled by the MPiec controller. Because A.95A is a warning, not an alarm, it is not necessary to prevent it from occurring, and the application can still run normally. A.95A can be masked using Pn800 for SGDV SERVOPACKs. Refer to the SERVOPACK documentation for the settings to mask A.95A. One possible cause for A.95A to occur (that the MPiec controller cannot handle) is if the HWBB input changes, causing STO, during motion. A.95A is a result of the SVON bit of the MECHATROLINK STATUS field being 0 (the servo is OFF), during the INTERPOLATE MECHATROLINK command. A.95A is expected and application code to handle STO condition does not require the INTERPOLATE command. Thus, the application can still run normally.

	How do I cure the "Socket Communication Applet Unavailable" error? Posted Date: 06/21/2013 Answer: The web interface for MPiec controllers provides a quick means to check system status and perform test moves via an Ethernet connection. The Machine Operations hyperlink will allow the user to manipulate and exercise the motion axes. On some computer systems, an error message will be generated that indicates "Socket Communication Applet Unavailable". This is likely caused by a missing or incompatible version of the Java Runtime Engine as an add-on to the web browser. The web interface requires Java version 1.4.2 or higher from Sun Microsystems. Combinations involving controller firmware, operating system, explorer version and Java version tested by Yaskawa are shown in the attached. If you continue to experience problems, install the most recent version which is supported by your MPiec Controller.

	How do I add external regenerative resistors? Posted Date: 12/14/2007 Answer: First, it is important to add a regenerative resistor with the proper resistance. Otherwise, damage to the ServoPack and/or poor performance may result. Please refer to the table in Section 5.6 of the Sigma II User's Manual [YEA-SIA-S800-32.2] for the minimum allowable resistance for each ServoPack model (see attachment below also). The user's manual also discusses calculating regenerative energy capacity. Once the amount of regenerative capacity has been determined, a resistor must be acquired to satisfy the requirements. Yaskawa offers a range of resistor pack units, and while they are designed and wired to work with particular sized ServoPacks, they can be rewired/reconfigured to work most any unit. Please reference the attached document for configuration and wiring details. Once a resistor has been acquired, it is connected between terminals B1 and B2 of the SGDH ServoPack. Be sure to remove the jumper between B2 and B3 (applicable to ServoPacks between 500W to 5.0kW). Now the external regenerative resistor's useable capacity must be calculated. There are two general variations to this: 1) Natural Convection Cooling. About 20% of convection cooled resistor's capacity may be used. For example, if a resistor has a nameplate value of 1000 watts, the maximum usable capacity is 1000Watts * 20% = 200 Watts (assuming natural convection cooling). This limitation is generally specified by the resistor manufacturer to insure high MTBF, so be sure to verify the capacity reduction in your specific operating environment. 2) Forced Air Cooling. About 50% of a forced air cooled resistors capacity may be used. For example, if a resistor has a nameplate value of 1000 watts, the maximum usable capacity is 1000Watts * 50% = 500 Watts (assuming forced air cooling). Lastly, the value for Parameter PN-600 (Regenerative Resistor Capacity) must be calculated and input. PN-600 is in units of 10W, so the above calculated valued must be divided by 10 and the result is input for PN-600. For the two examples above: PN-600 = (200/10) = 20, natural convection cooling PN-600 = (500/10) = 50, forced air cooling Attached Files: 99004a.pdf is external regen specifications for the Sigma II amplifier product. It outlines the minimum value resistor rating required for a particular model number and how to use/rewire the JUSP-RA04, 05, 18, 19 resistor packs to match that rating. Troubleshooting info Note: If an A.40 alarm (overvoltage) appears, it could be due to too much instantaneous power regeneration. A remedy could be to lower the resistance value of the shunt regen resistor (but be sure not to go below min rating). Note: If an A.32 alarm (Regeneration overload) appears, the RMS regen dissipating capacity must be increased. This alarm is governed through the Pn-600 setting) Attachments: 65KB Product Group/Line: Servo Products, SGDH Sigma II Topic/Sub Topic: Ask a Technical Question, Procedure - Policy, Start Up - Installation, Wiring Document Number: MNEN-5CJMRL Published Date: 12/14/2007 Share \| Rate Rate this article :	12/14/2007

	How does GA800 differ from A1000 when installing the drive outside of an enclosure? Posted Date: 01/11/2019 Answer: A1000 comes standard with IP20/UL Type 1 parts through 125HP (@480V). Larger A1000 requires a separately sold IP20/UL Type 1 kit for this kind of installation. GA800 requires a separately sold IP20/UL Type 1 kit for all ratings (smallest through largest) when installing the drive outside of a cabinet. The standard GA800 price has been adjusted to account for the IP20/UL Type 1 kit. This is a price advantage for many applications when mounting the drive inside of an enclosure.

	How does electronic thermal (motor protection) work? Posted Date: 07/13/2004 Answer: The motor heat characteristics are simulated by observing the motor current and operating frequency data. The motor is protected from overheating within its entire speed range. The motor characteristics differ by motor type, thus it is necessary adjust the inverter programming for the appropriate motor type, i.e., standard motors or inverter-duty motors. When dealing with multiple motors connected to one drive, a thermal relay is required for each individual motor. Most Yaskawa drives contain a UL approved motor overload protection such as Class 20.

	How does an SMC controller handle data which exceeds (or rolls over) the maximum value limit? Posted Date: 07/13/2004 Answer: Many programmers are concerned with overflow and what effect rollover will have on their addition and subtraction calculations. The SMC controller uses "two's compliment" math which handles rollover with no special programming. This applies to add interal status variables and user variables. To test this, Yaskawa has developed an example program that will perform a mathematical subtraction before, during, and after the rollover point. This makes calculating the difference between two numbers very easy, even when one grows past the maximum value. VAR1 and VAR2 are set to different very high numbers in the #TEST routine. The program then loops, the variables are compared, and the results are displayed. The variables are then incremented by 100,000. #TEST VAR1=2147483647-1000055 VAR2=2147483647-500055 #LOOP VAR3=VAR2-VAR1 MG "VAR1= ",VAR1," VAR2= ",VAR2," DIFF= ",VAR3 VAR1=VAR1+100000 VAR2=VAR2+100000 WT50 JP #LOOP Run this program on a SMC controller (using YTerm) and watch the terminal window for the values. After a few seconds, the variables will roll over, but the result of the subtraction will always be the same. Type "AB" in the terminal window to abort the program.

	How can variables be initialized in a Sequential Function Chart (SFC) Step? Posted Date: 07/07/2013 Answer: SFC Actions can initialize variables when a Step is activated by evaluating the rising edge of the Step.X variable for that Step. For example, if there is a Step called S_Perform_Move, the internal variable S_Perform_Move.X will be set to TRUE when the Step is activated. By using an R_TRIG function block to evaluate the rising edge of this status variable, it is possible to initialize variables on the first pass through the Action. It is also possible to use the F_TRIG function block along with the Step.X variable to create code that only executes on the last scan of the Action, see attached.

	How can the P5/GPD506 parameter settings be adjusted or changed while the bypass drive is running in bypass mode? Posted Date: 11/29/2005 Answer: The Test/Normal switch on the front of the Bypass panel is provided to test or set up the drive without actually connecting the AC drive to the motor. When in Test mode, the contactor on the input of the inverter is energized bringing 3 phase power to the inverter but the output contactor is left de-energized. The Digital Operator can then be used for programming or to issue a run command so that the inverter can be checked for normal operation. Note: A fault message (Fault code XXX message) will be displayed on the Digital Operator when the Test/Normal switch is in the "Test" position while in Drive mode. The Test/Normal switch should be in the "Normal" position when in Drive mode. The Test mode can be used when the Drive/Off/Bypass switch is in either the "Off" or "Bypass" position.

	How can source code be stored onto an MP2600iec Controller? Posted Date: 12/10/2019 Answer: During the download process, selecting the checkbox to include the source code zips the current project files and downloads them to the controller together with the compiled code. The zipped source can be used as a backup of the current project in case future modifications are necessary. It can be uploaded into the software development environment at a later time for editing and also provides another way to store the program in case of any data loss from third party servers or computers. Note: While the controller does have 3.5MB of flash memory available, only 1.4MB of that is allocated to MotionWorksIEC project storage. This is because there are scenarios where two copies are stored on the controller (totaling 2.8MB, leaving 0.7MB free for other user files such as Configuration and Cam/Data files, which are not included as part of the "user project".

	How can a Sequential Function Code (SFC) be programmed to reset after an unexpected interruption of the sequence? Posted Date: 07/07/2013 Answer: To handle a power failure, E-Stop, alarm, or other unexpected interruption to an SFC sequence, Yaskawa recommends executing a supervisory routine to reset the Step.X bits of each Step and therefore reset the SFC. The simplest place to add this is in the initialization Step of the SFC as an Action with an "S" (stored) action qualifier, see attached. The A_Supervisor Action runs each scan because of the "S" (stored) action qualifier. This code simply checks for a Boolean reset bit to set the each Step.X bit to FALSE, and then setting the first step's Step. X bit to TRUE. Care must be taken that any critical variables in the SFC are re-initialized during the SFC reset process.

	How can an absolute encoder be used as an incremental? Posted Date: 09/21/2004 Answer: There are some situations where a user may wish to use an absolute encoder as an incremental encoder: - On some models, such as SGMAH and SGMPH, the absolute encoder has better resolution than incremental (16-bit vs. 13-bit), which can lead to better performance and tuning. - If an incremental encoder motor is unavailable, then an absolute encoder motor could be substituted without operational change. - Absolute encoder needs a battery when operating, but when it's used as incremental, the battery is not needed. To set the SGDH servopack to read an absolute encoder as incremental encoder, set Pn002.2=1 Product Group/Line: Servo Products, SGDH Sigma II, SGMAH Sigma II, SGMGH Sigma II, SGMPH Sigma II, SGMSH Sigma II Topic/Sub Topic: Ask a Technical Question, Operation, Options, Parameters Document Number: MTN-5YYLS5 Published Date: 09/21/2004 Share \| Rate Rate this article :	09/21/2004
	How can alarms be reset in EtherCAT state SAFEOP? Posted Date: 02/09/2015 Answer: Alarms are only resettable if "Alarm Reset" is listed as "Available" for that alarm in the SGDV CoE User's Manual (Yaskawa.com document SIEPC72082904 section 9 Troubleshooting). Resettable alarms are reset using the "Fault Reset" bit of the Controlword (CoE object 6040h, bit 7. Refer to the SGDV CoE User's Manual section 8.6 Device Control). In SAFEOP, Process Data communication is not possible, but Mailbox (SDO) communication is. Refer to the SGDV CoE User's Manual section 6.3 EtherCAT State Machine. Thus, write the Fault Reset bit of the Controlword through Mailbox (SDO) communications to reset the alarm (if it is resettable) when in SAFEOP.

	How are Yaskawa Servopacks (or Inverters) connected to a five wire 400VAC power source? Posted Date: 03/12/2002 Answer: Germany (and other European Countries) uses a five wire three phase 400VAC. Three wires are power, one is neutral, and one is ground. The 5 wire system is used to get balanced 400 V phase to phase and 230V phase to neutral (400/1.732) so control voltage can be obtained without a control transformer. In this case, the feeder transformer is a wye configuration, while the 5th wire is the power system ground. Some plants ground the neutral, while others float it. In the case of Yaskawa inverters and servos: For normal use, we ignore the neutral and utilize the 3 power phases and earth ground (system ground). For CE, Yaskawa's smaller inverters (V7, J7, and small servos) require the main AC power supply to be wye configuration with the neutral grounded in order to limit voltage to 277V or less to ground. This is to meet voltage clearance (LVD) requirements for CE.

	How are the Electronic Gear Ratio parameters, Pn202 and Pn203, set for linear motors? Posted Date: 07/25/2005 Answer: The positioning resolution of the linear motor when used with the Sigma II SGDH servo amplifier in position mode is equal to the linear encoder scale pitch divided by 256. For a 20 micron pitch linear encoder (i.e. Renishaw RGH22B), the positioning resolution is 20 micron/256. The incoming position reference is scaled by the Electronic Gear Ratio. Pn202 is the Electronic Gear Ratio numerator, set to a default of 4. Pn203 is the Electronic Gear Ratio denominator, set to a default of "1". Therefore, with these these default settings, for every reference input pulse, the linear motor will move (4/1) x (20 microns/256) or 0.3125 microns, assuming a 20 micron pitch linear encoder. The Electronic Gear Ratio can be changed to allow for "friendlier" positioning units. For example, assuming a 20 micron pitch linear encoder: 1.) The desired position reference resolution is one micron (or 0.001mm). For every reference pulse, the linear motor moves one micron. To achieve this resolution, set Pn202=256 and Pn203=20. Now, for every reference pulse, the linear motor will move (256/20) x (20 microns/256) or one micron. 2.) The desired position reference resolution is 0.001 inch. Set Pn202=8128 and Pn203=25. Now for every reference pulse, the linear motor will move (8128/25) x (20 microns/256) x (25.4 inches/0.001mm), which is equal to 0.001 inch.

	How are registers in the MP9xx controller monitored from the PC? Posted Date: 09/06/2004 Answer: There are several ways to monitor registers in the MP940, MP930, or MP920 products. 1) MotionWorks+: If the original program was written in MotionWorks+, the "Data Monitoring" feature can be used to monitor the value of any user or system variable, including I/O monitoring. 2) MotionWorks Register List: MotionWorks ladder-based software has a Register List utility that allows the user to set or monitor groups of registers simply. 3) MotionWorks Tuning Panel: MotionWorks also has a utility called 'Tuning Panel', which allows you to set or monitor many individual registers. 4) HMI: Most major brands of HMI interfaces have Memobus drivers available for communication with Yaskawa MP Series controllers. 5) CamTool: CamTool allows tables of data (in the form of a generated cam table) to be sent to the controllers. (Requires MotionWorks or MotionWorks+ to be installed.) 6) CSVTool: A separate run-time software tool called 'CSVTool' allows CSV (Comma Separated Variable) files to be uploaded to or downloaded from the controller. (Requires MotionWorks or MotionWorks+ to be installed.) CLICK HERE for more information. 7) EXCELTool: This Microsoft Excel spreadsheet macro allows contents of specific cells to be changed by hand and sent to the controller. Registers can also be read from the controller. (Requires MotionWorks or MotionWorks+ to be installed.) 8) Visual Basic: Yaskawa has developed a sample application in Visual Basic utilizing a readily available Modbus driver. The demo program shows how to use this Modbus driver to retrieve (M) registers from the MP9xx controllers via Memobus. It allows up to three "M" registers in the MP9xx to be read and one to be written at a time. The Visual Basic program does all the data manipulation necessary to use the Modbus driver as a Memobus communication tool (required for MP9xx). Both the compiled program and the source code are available.

	How are pLimit_PositioningError and sPosition_CompletionWindow used to control positioning accuracy? Posted Date: 05/21/2001 Answer: The goal in a positioning system is to get from Point A to Point B (see attached SmplMove.pdf). But how close to Point B must the system be? Also, how much deviation is allowed on the way to point B? MotionWorks+ has a couple of system parameters that can help the programmer manage this. As with all of the system parameters, these are described in the "Programming Concept" section in your MotionWorks+ software manual. pLimit_PositioningError: This parameter is the maximum allowable following error that the servo will be allowed to accumulate before an alarm is generated. This can occur during any part of the move. Usually, the maximum following error occurs during acceleration. If the following error exceeds this value, an A.9F alarm will be generated, and the system bit mPosition_Error_Exceeded will be set to "1". Even if a system needs to be very precise at the end of the move, the maximum error during the move will be much higher in most instances, depending on the acceleration. Remember to set the value of pLimit_PositioningError sufficiently high. This value will have NO EFFECT on the final position precision. sPosition_CompletionWindow: This parameter defines the maximum distance allowed between the final target and the servo for a move to be considered complete. If an index move with the "wait for completion" property set to "true" is used, program execution will be stalled until the position of the motor is at the commanded position, plus or minus this window. Setting this value larger just means that the final target need not be as close to the target before execution continues. The default value of sPosition_CompletionWindow is 0.0 user units, meaning that the motor has to be EXACTLY at position before execution can continue. With the default tuning gains in the amplifier being so low, it is often difficult to achieve this level of precision, and the program will appear to "freeze" on the index block. In reality, the program is waiting for the position to get within the window, something that the tuning gains are not high enough to accomplish. You may even find that a small push into position will cause the move to complete and the program to continue. Neither of these parameters will determine how closely a system will follow the command, only how the system will react to the error. The following error during the move and the precision at the end of the move are always determined by the tuning of the system. If the system is generating A.9F errors due to excessive position error, or if the program is hanging while waiting for a move to complete, then these are the parameters to check. If these parameters are set appropriately, then the tuning needs to be improved.
