RECOMMENDATIONS:

• Before wiring to the VFD, use a multimeter to verify that you do get a 0-10vdc proportional to the commanded speed and that the relays are clicking as expected when you command the spindle.
• After wiring, make sure to configure the VFD to take the control signals from the terminals.
• Keep in mind that you need to configure the VFD to take the control signals through the terminals:

  • COMMAND	VALUE	DESCRIPTION
    Pn 03	4	External 0-10V signal
    Pn 04	2	External signal control

• 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.
