	How is an MP920's SVA servo module initially set up to ensure successful automatic reading of an absolute encoder motor? Posted Date: 07/13/2004 Answer: The following steps outline how to successfully set up an MP920's SVA module to read an Absolute Encoder Motor: 1) The value fixed parameter number 8, "Number of feedback pulses per rotation", must be the same as the Pn201 value (PG Divider) in the Servopack. This ensures proper absolute position calculation in the MP920. 2) The Servopack must be wired exactly as shown in the MP920's Motion module manual or use Yaskawa's pre-wired cables (SIEZ-C887-2.5). This ensures proper transmission of the absolute data. 3) If the Servopack has the Parameter, Pn000.0 = 1, for reversal of positive direction, then fixed Parameter #4 (Absolute Encoder Rotation Direction) of the SVA module must be set to "negative". If Pn000.0 = 0 (factory default) then Fixed Parameter #4 must be at its factory default: "positive". 4) In order to have the SVA automatically read the Absolute Encoder on power up, bit 6 of fixed Parameter 14, "FUNCTIONS" must be left at factory default of OFF (0.) In addition to this setting, the MP920 and Servopack control power must come up at the same time. If they do not come up at the same time the "J" warning will display on the SVA module. If a read via application program is desired, the bit 6 of fixed parameter is set to ON (1) and the read is initiated by the application program. 5) The use of a Sigma II Servopack (SGDH) requires bit 9 of fixed Parameter 14, "FUNCTIONS" to be ON (1) or "enabled". It is labeled "Sigma 2 Servopack" when looking at the windows dialog box used to set the bits in Parameter 14. 6) It is best that the axis not be in motion when the absolute encoder is being read. If it is moving, the maximum rotation allowed is 5 RPM. 7) It is highly recommended that the application program waits 500mS before enabling the servo at OBC0010 until after the IBC000A (Absolute read complete signal) has transitioned from OFF (0) to ON (1.) This rule should be adhered to if the read is automatic or from the application program.

	How easy is it to use Compass on custom mechanisms? Posted Date: 02/09/2021 Answer: Compass can be used with custom mechanisms that use a world coordinate system. Custom mechanisms would be used through our SyncGroupToGroup function block via a nD Gantry that has virtual axes and the custom mechanism would use a custom group where motion is controlled via kinematic equations to determine position commands. These position commands are then input to a Y_GroupDirectControl function block (inside SyncGroupToGroup).

	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 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 the controller error “The PLC could not perform a warm start, so the PLC performed a cold start.” be avoided so that the retained variables are not reset? Posted Date: 02/26/2018 Answer: When a project has local retained variables, and only a boot project is downloaded to the controller (by using the More button in the project control dialog), the controller will display this error after it is rebooted. To avoid this, make all retained variables global, or when downloading, download both the project and the boot project by using the Download button in the project control dialog. This is a known issue that will be fixed in a future release.

	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".
