	The VG3 or VCD703 - Vector Drive uses terminals 30 and 31 as inputs for a motor thermistor. With no thermistor connected, the drive faults immediately. Is it possible to use a motor without a thermistor? Posted Date: 06/07/2007 Answer: Yes. In parameter On-02, change the second digit from the right [x x 1 x] from a "0" to a "1". This will allow "Control without thermistor".

	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 Motionworks IEC software stopped running after installing InteractX software? How can I recover from this? Posted Date: 03/04/2010 Answer: The InteractX software removes a required registry item required by MotionWorks IEC. To correct this issue: 1. Navigate to the installed location of Motionworks IEC (usually C:\Program Files\Yaskawa\MotionWorks IEC Pro). 2. Run the SETUPEX.EXE file by double clicking. 3. Reboot the computer. MotionWorks IEC should be able to run again.

	The GUI displays mm. How can it change to inches? Posted Date: 07/23/2021 Answer: To change the units used in the Position Display navigate to the Machine Configuration page, drop down cartesian axes, check the box for Override and choose your preferred units to be used in the Position Display. To change the units of your commands in a G Code file you can either execute a G20 (set commands to be in inches) or a G21 (set commands to be in mm). It is common that a G Code file will specify G20 or G21 at the beginning of the file.

	The GPD 515/G5 displays a parameter, but does not let me change it. Why? Posted Date: 07/13/2004 Answer: Parameter A1-01 controls access to all parameters that are available in the control method being used. A setting of 'Advanced' 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.

	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 E7L will not run the motor in Hand or Auto mode. What can cause this? Posted Date: 10/27/2005 Answer: Possible Solution: 1. The ribbon cable UWR00562-1 may be partially plugged or loose between Electronic Bypass Keypad (A3) and Electronic Bypass Control PCB (A2). Attempt to reseat or push the ribbon connector in as needed on one, or both ends to correct this problem. (See attachment.) Other symptoms of this problem include: 1. Drive LED flashes. 2. Stop LED is lit. 3. Contol Power LED is lit. 4. No Ready LED. Refer to TM.E7L.01 the E7L Drive Bypass Technical Manual for more information.

	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.
