	Is there a quick way to reset SGDH servo alarms without using PC software? Posted Date: 05/21/2001 Answer: To reset an alarm on a Sigma II amplifier, just press the middle two buttons ("up arrow" and "down arrow") on the digital operator at the same time. This has the same effect as the ALM-RST input or executing the Fault Reset block in MotionWorks+. Not all alarms can be reset this way; some require you to cycle power. For a list of alarms that can't be reset, see your Sigma II User's Guide, section 9.2.3. The alarms with a single asterisk require the power to be cycled. If an external controller is attached to the SGDH, the motion program must be aborted before resetting the servo alarm to prevent an unsafe situation.

	Is there a procedure for starting-up a Sigma II Servo System with an Absolute Encoder? Posted Date: 07/13/2004 Answer: Commissioning a Sigma II (SGDH) Servopack. When using an absolute encoder: In the case where an ABS encoder is used, the ABS encoder should be set-up before any option units are attached and before the trial operation is commenced. Section 5.7 in the users manual should be read and understood before an Absolute encoder is used for the first time. Basic Servopack/Servomotor Check: Trial Operation Section 4.1 in users manual. 1) Direction- Verify the direction by energizing control power (L1C & LC2) only, then monitoring Un-000 (7.1.7 Monitor Mode - 'Actual Motor Speed' [RPM]) for positive and negative numbers as the axis is moved by hand. 2) Change direction reference if required: This is done by changing the value in Pn-000.0 between 0 and 1. Don't forget to cycle the power if a change is made. 3) JOG the servo system: Jog is initiated with Fn-002 (7.2.2 'JOG operation using Digital operator'.) Always remember that the default JOG Speed is 500RPM and is set at Pn-304. Main Power (L1, L2 and L3) should be ON in order to JOG. When using Option units: 1) If an absolute encoder exists, set it up first (5.7 'Absolute Encoders'). 2) Check the Servopack and Servomotor connections and do the trial test described above (4.1 'Two Step Trial Operation') 3) If all is well, power everything down. Then connect option unit and re-power. 4) Adjust additional user parameters added to the system related to the option unit's existence. Resetting a SGDH (Sigma II) Servopack to factory default: 1) Fn-005 (7.2.9 'Initializing Parameter Settings') 2) Fn-006 (7.2.5 'Clearing Alarm Trace back Data') This step is not mandatory, but is suggested. 3) Fn-014 (7.2.13 'Clearing Option Unit Detection Alarm') If no option unit was used, this is not required.

	Is there an alternative explanation of the term "User Units" pertaining to Yaskawa's electronic gearing built into the Servopacks and JUSP-NSxxx option board products? Posted Date: 07/13/2004 Answer: User units are a description of the resultant position units after electronic gearing parameters are adjusted. This is a feature used when a Yaskawa Servopack is in position mode. A Servopack may be in position mode under two circumstances: accepting pulses from a stepper motor indexer or when an application module such as an NS600, NS300 or NS500 is attached. Electronic gearing is expressed as a ratio. The result is that the position can be pulsed or commanded in logical user units, not just motor-encoder counts. Positioning in user units allows the application programmer to set position targets in realistic units rather than encoder counts. The Ratio is expressed as B/A, where B and A are integers. 'B' is the number of Quadrature [x4] encoder counts the motor will move for a given 'A' number of commanded user units. If B=300 and A=20, then for every 20 user units sent to the Servopack via pulses or a position command issued from an option card, the servomotor will move 300 encoder counts. If only 10 user units are commanded, then the servomotor will move 150 encoder counts. To see the equation and further information, please see the attached .PDF file.

	Is there a list of technical recommendations for safe guarding an MP940 Servo Control System against overspeed conditions? Posted Date: 08/29/2005 Answer: Yes, below is an example written up for an MP940 Indexing System with a Direct Drive Motor, but can also be applied to various other applications: Product Description Ordering Part Number Direct Drive Motor: SGMCS-2ZN*** Sigma II Amplifier: SGDH-30AE MP940 Machine Controller: JEPMC-MC400 MotionWorks Software: MPE720 The Yaskawa 3kW Direct Drive Servo, SGDH Sigma II Servo Amplifier, MP940 Machine Controller, and MPE720 MotionWorks Software is a programmable system capable of operating the motor in various applications such as absolute rotary motion indexing. To insure that the system controls the motor in the way the machine designer expects, the system design specifics should be considered. Since the Yaskawa system is scalable, it allows the designer to add modules for increased ability and flexibility to suit the needs of various applications, including segmented variations of indexing applications. The description below describes some features of how each module monitors and handles speed concerns. 1) Motor: SGDH servo amplifier has a feature that will auto-id the SGMCS-2ZN direct drive motor through the serial encoder, and identify that it has a max speed of 250 rpm. If the encoder wire is unplugged, or if the serial communications data becomes compromised due to electrical noise, the system will automatically detect it, and fault out on an A.C* alarm. There is more information about these alarms in the manual or in our faq site, faq.yaskawa.com. 2) Amplifier: SGDH servo amplifier has a feature that will fault out on overspeed A.51 alarm if the motor exceeds 250 rpm by an amount. Alarm detection occurs within about 1msec of when the servo amplifier calculates that the speed has reached 20% above max speed. Once the alarm is detected, the amplifier faults out on overspeed, and annunciates the alarm. The motor will stop according to stop condition parameter settings (coast or dynamic brake, see Pn001). - The alarm output of the SGDH amplifier should be wired in series with the E-Stop circuit to insure main power gets dropped out in the event of a Servo Amplifier Alarm. Refer to section 5.5.2 in the MP940 Design and Maintenance Users Manual, SIEZ-C887-4.1. - The Servo Amplifier has a feature that allows the servo to be jogged regardless of the state of the controller, overriding the controller. This is available for startup and testing purposes, and ease of use. When the machine is commissioned for production, it is recommended that this feature as well as access to any parameter be locked out. SGDH Parameter access through the front panel can be locked out by setting Fn010=1. Refer to section 7.2.12 in Sigma II Servo User Manual, YEA-SIA-S800-32.2. 3) Controller: MP940 controls the servo amplifier via Dual Port Ram interface connection, and should be used to enable/disable the servo, as well as supply the control reference signal. This interface is completely digital, and handshakes communication on a watch dog timer. If the CPU faults out on a serious error it will cause a watch dog error, and the amplifier will automatically fault out on an A.E2 alarm, disabling the servo. - It is recommended that all low power control signals be wired to the MP940 I/O connector with exception to the following which wire to the 1CN connector: Positive and Negative over travels inputs, Home Latch or Motor Position Latch input, and Pulse Generator output. All 1CN inputs can be used as programmable inputs monitored via register IWC025. 4) Software Setup: MPE720 MotionWorks software programming environment is used to setup, program, and monitor the MP940 and servo system. Fixed parameters and setup parameters are available for flexibility and assurance of control. Proper setup of these parameters as recommended in the users manual will insure the direct drive servo positions accurately and as expected. It is recommended that all adjustments to the setup and parameters be made from this software. OWC004/OWC005 are also available parameters that can be set to limit speed (refer to manual section 11.3, SIEZ-C887-4.1 position mode preparation info when motion command is used, see control mode block diagram 11.21). - During software setup, its important to characterize a complete set of tuning gains for the mechanical system, first without the load, and finally with the load (Primarily parameters: Pn100, Pn101, Pn103, OWC010, OWC011, OWC035, and all low pass or notch filtering). See section 6.4.3 for a complete set of gain-related parameters. Taking measurements of torque and speed profile during a positioning move cycle, and recording this information is called 'servo gain baselining'. Documenting this is recommended for future reference when troubleshooting a system. Guidelines on Tuning can also be found in Example FAQs on faq.yaskawa.com: BFAR-5DHHXL, MTN-5WZJZ7. - Any constant or variable values that are considered default parameter settings for the machine installation, should be hard coded into the Startup A drawing, so that the A drawing will store the hard coded values into the register which is used in the application program. This insures that all default values are stored in the program in the event that an MP940 controller is swapped out. Parameter set changes during machine operation can be set by downloading recipes from an HMI, or tweaked from the HMI. 5) Software Programming: There are several ways to program the system because of the variety of applications, including indexing. If the chosen method to position is by setting the Motion Command Code to positioning (OWC020=1), then the final position command should be conditioned and checked, then sent to the Command Register (OWC012). Good practice for coding in ladder would also include interlocking code to protect the overall control of the system such as: servo ready/fault check, over travel check, safety I/O check, speed command verification and limit checking, actual speed calculation check, etc. - It is also recommended that a general purpose output be dedicated to interlock in series with the hardwired E-Stop circuit, preventing the E-Stop circuit from engaging main power until the MP940 code is running and controlling the output. If software safety check code detects abnormalities, it should set the output to off, causing dropout of E-Stop power. This is possible because the MP940 and SGDH amplifier control power is separate from the servomotor main power. - In instances where load will be changing, changing gains on the fly should be considered. If the system is rigid enough, it may be possible to linearly scale the gains using Pn103, otherwise, gain relationships may need to be adjusted. This can be determined through testing. - Software application code can be secured by password protecting through the user management section. Seven levels of read and write access protection are available. 6) Software Testing and Verification: Good practice for machine commissioning is to validate program functions through sign-off testing. This is often performed with the help of a checklist that shows columns for: Test item, verification test, acceptance criteria, and a place for the tester to sign and date. 7) Software Maintenance: Once the program and system has been tested, the application program should be baselined by assigning a production version, and should be backed up. In addition, the critical control software modules should be secured with password protection to support authorized changes only through an 'application software version control process'. 8) External Devices: HMI variable settings should be limited to insure the system does not operate as unexpected when the operator (or external device) enters set values outside of the expected range. If needed, an external speed monitor with independent circuitry could be connected, and hardwired to provide a final layer of independent overspeed protection. 9) System Level: Layered protection at each level (motor, amplifier, controller, setup, programming, testing, maintenance, external devices) will insure mitigation as well as contingency execution in the event that any particular safety element is compromised by mistake (example, if someone changes a programmable value accidentally, or by-passes a wired protection). Ultimately each application is different, and demands a varying level of protection against anomalies based on a balance of safety requirement and feasibility of cost. These are all at the discretion of the installer. It should also be recognized that the operators or users of this machine may alter the system at any point based on the ease of access to bypass functions or features. For this reason, it is also recommended that lock-out tag-out hardware be installed on the control enclosure, as well as a maintenance safety procedure be written to support that. In any of these cases, the Direct Drive motor, SGDH amplifier, MP940 controller, and MPE720 software is designed to operate together, and if wired, installed, setup, programmed, and maintained in accordance to the respective product users manual, and utilizing best practices, the motor will position as expected.

	Is the MP-940 capable of operating Yaskawa linear motors? Posted Date: 01/14/2005 Answer: Yes, it is possible when using MotionWorks. The only difference between using a rotary motor and a linear motor with the MP-940 is to select Linear Type vs Rotary Type in the SVA section of Module Configuration. By doing this, the additional parameters for Linear Motors are displayed in the "ServoPack" tab. There are three, however, that will require immediate attention to allow motion to occur. Please reference the users manuals for information regarding all other parameters. SGDH Parameter Settings: 1) Pn280: Linear Scale Pitch (micrometers), the ServoPack will remain in an alarm state until this is set. 2) Pn483: Forward Force Limit (% of rated), factory default is 30% (for safety), set appropriately for application. 2) Pn484: Reverse Force Limit (% of rated), factory default is 30% (for safety), set appropriately for application.

	Is it possible to simply control speed in a Sigma II amplifier without a controller? Posted Date: 10/24/2002 Answer: Yes. A speed control feature is integrated into Sigma II amplifiers. This mode of operation is called Contact Input Speed Control. It allows the user to initially set three different motor speeds with parameters, then select one of the speeds externally using a contact input. For details and learning more on how to set this up, please refer to section 5.2.6 of the Sigma II user's manual.

	Is it possible to route the POT and NOT signals through DeviceNet on an MP940D? Posted Date: 09/05/2001 Answer: Technically Yes, but care must be taken to insure safety. Positive Over Travel (POT) and Negative Over Travel (NOT) are considered critical I/O, and their function is controlled within the SGDH amplifier by default. This strict control insures that motion will stop given an OT situation. Caution should be used when trying to control such an event over a network, particularly if the network is disconnected (in this case, the controller must immediately stop motion if network heartbeat is lost). These inputs which are wired into the SGDH, are then mapped into the MP940 controller (every 125microsec) to be used for further decision making in the MotionWorks or MotionWorks+ program. All 7 isolated inputs into the SGDH 1CN connector can be read from IWC025 bits 0,1,2,3,4,5, and 6 (or "Sigma_*" inputs from MW+). To view any of these through DeviceNet, simply map the inputs to a DeviceNet output, then each DeviceNet scan will have updated info for other nodes (this is Polled I/O).

	Is it possible to prevent the momentum of a linear motion system from carrying the table (or carriage) past a limit switch? Posted Date: 05/21/2001 Answer: The Sigma II amplifier is very robust and protects the motor from harming itself. The Sigma II has overtravel functions built-in to the amplifier, but it is important to understand the settings to use the overtravel feature. The Sigma II offers three options which are set in Pn001.1: 1 & 2) Pn001.1=0, will stop the travel the same way a servo OFF or alarm stop mode (Pn001.0) is handled. This may be a coast or a Dynamic Brake. 3)Pn001.1=1, will stop the travel by using the Emergency Stop Torque (Pn406) to stop the motor. The Dynamic Brake and the Emergency Stop Torque are the fastest ways to stop the motor. The "dog" or pickup for the overtravel switches, especially on fast moving machines, should be sufficiently long enough so as not to over shoot the switch and end up in a dead zone. If an overtravel occurs (input goes low) the drive will automatically begin to stop the motor. If the momentum moves the table beyond the switch while stopping, the overtravel will be reset and the motor will try to continue to the move. This may cause damage to the system mechanics. An overtravel can be latched in the controller through programming. When programming a controller like the MP940, caution must be taken to set up the overtravel detection handling within the supervisory program. The program needs to prevent any movement in the direction of the overtravel, but must also allow the operator to jog back off the switch in the opposite direction.

	Is it possible to isolate or split the encoder output signal from an SGDH PG output? Posted Date: 07/13/2004 Answer: Yes, the best way to split the encoder output signal from an SGDH amplifier (i.e. connecting the PG output to multiple receivers) is to use a differential signal splitter. BEI Technologies sells an Optically Isolated Encoder Driver Module (three channels Differential) which does the following: 1. Provides optical isolation of three complimentary signals (A & /A, B & /B, Z & /Z) 2. Allows PG connections up to 500 ft. in length 3. Allows encoder splitting to up to 8 receivers BEI has produced the attached document which contains more information about this product.

	Is it possible for an AC induction motor, driven by a Yaskawa V7 inverter to "follow" a Yaskawa Sigma II servo system using the Servopack's (SGDH) encoder output and the Inverter's "reference pulse" (RP) input? Posted Date: 04/11/2006 Answer: Yes it is. The V7 has a "reference pulse" (RP) input that accepts a pulse frequency as a speed command, and drives the AC induction motor at a proportional speed (reference frequency.) The speed at which the AC motor follows the servo system depends on digital settings in both products. An excel workbook is provided to test both Servopack and Inverter settings before they are actually applied in the two products. Servopack and Inverter Settings: Since the Servo system is commanding pulses to the inverter, the servomotor speed and the value set in the encoder dividing parameter of the Servopack (Pn201) directly effects AC induction motor speed. In order for the inverter to accept the pulse command from the Servopack, the RP input for the inverter must be active (n004 = 5). Inverter parameter n149 scales the "command frequency" to "reference frequency". The other limiting factors in the inverter are the minimum frequency the inverter commands and maximum frequency settings. The minimum frequency reference of this inverter is 1.5Hz. The maximum frequency is the set value in n011, and is commonly set at 60Hz. It must also be noted that only one of the two channels of the Servopack's encoder outputs are used to command the inverter. The dynamic speed range of the AC induction motor (1.5 ~ 60Hz) driven by the inverter is the limiting factor in this system. However, it is also true that the settings in both the Servopack and the Inverter affect the final speed of the AC induction motor. Due to this dependence of the settings in both products, along with the common requirement to obtain reasonable dynamic range of the AC induction motor, an Excel workbook ("Servopack Master V7 slave.xls") is made available. Using the workbook: The workbook has two spreadsheets. One includes the instructions, the other (Servo-Inverter tool) will predict the resultant reference frequency speed of the inverter driven AC induction motor. The user needs to provide the "Servo-Inverter tool" spreadsheet with the digital settings of both devices, and the speed of the servo system. This spreadsheet has yellow colored cells where the servo system speed and the parameter setting of each device are entered. The results, displayed in bold blue characters, include the frequency command of the Servopack's pulse output and the frequency reference generated by the inverter to the AC induction motor. A sample connection is attached to this document (.JPG) and also included is a drawing of connections with tested device settings.
