	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.

	How are Modbus/TCP update rates set when the MPiec controller is configured as the Modbus/TCP Master? Posted Date: 06/26/2013 Answer: When a Modbus/TCP server (slave) device is added to the client configuration of the MPiec controller(MPiec acting as the Modbus/TCP Master), the device needs to be assigned to a task and an update interval (poll period) has to be specified for that server device (See the attached .PDF File for examples and further information).

	How are cam tables organized? Posted Date: 05/21/2001 Answer: The first point in the cam table is the number of master/follower pairs in the table. The subsequent points are the master and follower data points. If any master position is not found in the data table, the value will be interpolated from the nearest points. This interpolation is linear, so any "curved" sections of the cam table are actually made up from several small "straight-line" segments. The attached document, CamTable.pdf, will explain this function further.

	Hbb fault occurs with the H1,H2 and HC jumpered, what else could the issue be? Posted Date: 08/28/2012 Answer: A Hbb fault can be caused by improper use of the drives (S1-S8)digital inputs. If a customer is using the drives internal power supply and uses SC as the ground, this will cause a Hbb fault. Please use SN when using the drives internal voltage in sinking mode. (See attached.) As a note, the drive can utilize the 2 separate sources of power for the safety digital inputs and the (S1-S8) drive, but does not pertain to the Hbb alarm we discuss here.

	During a generator to line transfer, the drive attempts to catch an already moving motor and faults with OL or OV. What steps can we take to prevent these alarms from occuring? Posted Date: 09/16/2013 Answer: Make sure the motor/drive system is auto tuned. This provides the drive with information necessary to successfully catch a moving motor. For more information please refer to SIEPYAIZ1B01, the technical manual.

	During a generator to line power switchover, Uv1 results. Restart is not attempted. A manual reset is required for drives running motors. The transfer takes less than a second. Is there any fix for this issue? Posted Date: 09/16/2013 Answer: Setting L2-01 (Momentary Power Loss Operation Selection) to setting 2: Enable while CPU is active. Enabling Power loss ride while CPU is active, causes a baseblock, a hard stop of the firing mechanisms to the motor. This prevents a Uv1 condition, and allows the drive to ramp up when the under volt condition is over. This fix may need speed search to be enabled, please see the related FAQ link for OL or OV after generator to line transfer for assistance. For additional information, please refer to SIEPYAIZ1B01, the technical manual.

	Do you need to have the Control Power on in order to use the Dynamic Braking features of the Sigma-5 Servopack? Posted Date: 03/06/2014 Answer: If the Control Power is turned off before the Servopack receives the SV_OFF command, then the stopping method will vary by the Servopack model. These models will stop their motors by coasting in this scenario: SGDV-330A, -470A, -550A, -590A, -780A, -280D, -370D. These models will stop their motors by using the dynamic brake in this scenario: All other Servopacks except: SGDV-330A, -470A, -550A, -590A, -780A, -280D, -370D. If the Main Power is turned off before the Servopack receives the SV_OFF command then the servomotor will be stopped by use of the dynamic brake functionality. If you wish to have the servomotor coast to a stop when the Main Power circuit or the Control Power circuit is turned off before the SV_OFF command is received, then you will have to use an external method to disconnect the UVW phases to the motor in this scenario. If the SV_OFF command is received before the Main Power circuit and the Control Power circuit are turned off then the stopping method can be controlled by parameters in the Servopack (PN001).

	Do Yaskawa drives have a lock-out prohibiting setting or changing of parameters? Posted Date: 06/08/2007 Answer: Yes, most all Yaskawa drives posses parameter security that helps prevent inadvertent setting changes. The instruction manuals for the drive explain this function in more detail. Use the following instructions to obtain write access for the drives described below: For the V7 drive: Parameter n001 controls the access to all of the parameters. A setting of "0" allows no parameters to be changed, while settings of "4" or '5' allow all parameters to be changed. Settings "1" through "3" are increments of the level of access allowed. For the P5 or PC5 or GPD506 drive: Parameter n001 controls the access to all of the parameters. A setting of "0" allows no parameters to be changed, while settings of "3" allows all parameters to be changed. Settings "1" and "2" are increments of the level of access allowed. For the G5 or GPD515 - General Purpose Drive , G5HHP - Hi Horsepower G5 Drive: Parameter A1-01 controls access to all parameters that are available in the control method being used. A setting of "Advanced" in this parameter allows all of the available parameters of the current control method to be changed. Some parameters are not available in some control methods. Refer to Appendix 1 in the technical manual.
