• Keep in mind that you need to configure the VFD to take the control signals through the terminals:
      PD001 1 Run from Terminal. 
      PD002 1 Take Reference Speed from Terminal
  • Run the spindle at different speeds and test with a DMM that you are getting a 0-10vdc from the analog output terminals that is proportional to the commanded speed.  The Relays should also activate to start the spindle in the commanded direction.  This will confirm that your configuration is OK.
