	The V7 Drive Jog Reference (S7) command is given. Why doesn't the motor move? Posted Date: 07/13/2004 Answer: The Jog Reference is not a 'run' command. It merely switches the speed reference from the selected frequency reference (terminal FR for example) to the internal Jog frequency reference (n032). To make the drive run at jog frequency, energize both the run command (S1) and the Jog Reference(S7). As an alternative to wiring a second digital input: A "Jog Forward" command can be achieved on the V7 by adding a diode (common Radio Shack rectifier diode). The following conditions have to be met... 1. The digital inputs must be set to "NPN" . 2. The drive must be set for "2-wire control" Add the diode between the jog input (S7 for this example) and the Run input. Anode towards S1, and Cathode towards S7. Note: Earlier versions of the V7 Drive were named GPD 315/V7, GPD 315 or VS Mini V7.

	The GPD/515G5 instruction manual (TOE-S616-10.13) (pages 21-22) specifies that input fuses should be used on the installation of these drives.--Is fusing required or is a circuit breaker sufficient protection for the inverter?--If fusing is not required, what characteristics of MCCB should used be to protect the drive adequately? Posted Date: 06/08/2007 Answer: In the U.S., two types of branch circuit protection are required by local and national codes, branch circuit overload protection and branch circuit short-circuit protection. This protection is necessary to protect the circuit feeding the device (mainly input wiring). See attached for full details.

	The E7 drive inside the bypass enclosure unit doesn't have the Hand, Off or Auto buttons that are shown in the E7 manual. How can the drive be run locally? Posted Date: 07/13/2004 Answer: To limit confusion, the Hand, Auto and Off buttons on the keypad were disabled and a membrane/sticker was placed over the buttons on the face of the keypad. This is done only on units that have a seperate H-O-A switch on the door of the enclosure.These functions can only be accessed manually, by adjusting the Hand/Off/Auto switch located on the front panel of the bypass unit. They are peripheral methods for changing operation methods. The purpose for this is to limit confusion by having only one Hand/Off/Auto control.

	The Alarm output on the CACR HR Servopack no longer works. It is always open (or closed) regardless if the servopack is in an alarm state or not. What causes this situation? Posted Date: 03/12/2002 Answer: Assuming the Servopack 's Alarm output is wired correctly, the most common problem is that the relay's coil resistance is too low and the output has "burned out." The output photo-transistor used on the HR- Servopack (as well as most all of Yaskawa's servo products) is designed to handle a maximum of 50mA through it. The maximum voltage level allowed across the photo-transistor when OFF is 30VDC. Therefore, the safest selection is a relay coil with at least 600-ohms. If the power supply is a regulated 24VDC, then 480-ohms is acceptable. The second most common problem is connecting a relay with a "fly wheel diode" incorrectly and shorting the power supply accross the output. Remember that the Alarm outptus are ON (conducting) when NO ALARM is present. Therefore, if the relay's coil resistance is too low, it will damage the output.

	The "sleep" function can only be used when PID is enabled. If an analog (0-10VDC or 4-20mA) signal for speed reference is used, is there any way to use "sleep" without enabling PID? Posted Date: 11/29/2005 Answer: Yes. The minimum frequency must be kept at 1.5 Hz, and the "Prohibit Frequency" parameters will need to be used. Set parameter n062 equal to the midway point between 1.0Hz and the desired sleep frequency. Set parameter n064 equal to the difference between the midway point and 1.0 Hz. Example: A sleep frequency of 20.0 Hz is desired. 20.0 - 1.0 = 19.0 Difference = 19.0/2 = 9.5 Midway point = 1.0 + 9.5 = 10.5 Hz Set n062 = 10.5 Hz Set n064 = 9.50 Hz -- When starting up, the output frequency will remain at 0.0 Hz until the reference signal reaches a minimum of 20.0 Hz. -- With a decreasing frequency reference, the output frequency will level off at 20.0 Hz as the reference descends below 20.0 Hz. When the reference goes below the midpoint (10.5 Hz in the example), the output frequency will then ramp down to 0.0 Hz. For more information, please see TM4506.

	SVE -- Fault Code Description Posted Date: 06/08/2007 Answer: Digital Operator Display Text: SVE Zero Servo Fault Description: In the zero servo mode, the motor shaft has rotated 10,000 non-quadrature PG pulses from the home position. Possible Cause(s): Torque limit or zero servo gain set too low, load torque excessively Corrective Action: Verify the program parameters B9-01 zero servo gain and torque limit settings L7-01 ~ L7-02, check for noise on the PG signals. For information on resetting a fault on G5, E7, F7or G7 Drives, see FAQ# DRV-5P8PGJ. For more information and a complete list of fault codes see the following manuals TM4515 and PP.P5G5.01.

	Sometimes my machine power-up position is incorrect even though I have an absolute encoder on the motor. What is causing this issue? Posted Date: 05/19/2015 Answer: The absolute encoder rollover value must be properly calculated and stored in servopack parameter Pn205. This parameter is the Multi-Turn Limit Setting. It is necessary to set this value properly for rotary applications which move infinitely in one direction and utilize an absolute encoder. Example applications include indexing tables, spindles, turrets, winders, and conveyors. Pn205 allows the absolute encoder to synchronize itself with the mechanical load's position. The value must be chosen so that the number of turns tracked by the absolute encoder of the motor is an integer multiple of the desired mechanical cycle of the mechanism. When Pn205 is set incorrectly, the mechanism's home position may not be correct after a power cycle. Please see the attached documents that illustrate how to calculate Pn205 with three example applications. IMPORTANT NOTE: After making a change to Pn205 and cycling the power, the drive will display alarm A.CC0 (Multi-turn Limit Disagreement Error). This alarm is fixed by executing the "Multiturn Reset" function found in the web server (section "Machine Operations", tab "Drive Pn"). After executing this function, cycle power again to clear the alarm.

	Some shape cutting OEMs consider their front-end interface as their differentiating feature over competitors. How would you make Compass attractive to OEMs like this? Posted Date: 02/09/2021 Answer: One key benefit of Compass is the OEM branding. Typically, OEMs who already own their custom front end may find their front end outdated and difficult to support. Yaskawa Compass provides OEMs with a complete and flexible solution while giving them the ability to maintain their own unique branding.
