Air cooled spindle?

Hey Joe,

@Morelli

I can set PD141 to 110, but PD142 will not go any higher than 11.0 for the current rating of the motor. The motor plate shows a 12A rating for the motor.

Possibly the VFD does not deliver more. What is its rated output power i.e. what is the model you have?

@Morelli

Also, it appears by DVM that pin 4 of the spindle connector is in fact grounded to the spindle housing. With that, I assume I can carry a shielded four conductor from the spindle and just bring pin 4 into the earth ground at the Haunyang?

This is correct and mandatory.

Also don’t forget to set PD143 “Number of Poles”. It may be factory set to “4” which may be wrong if you purchased a 24,000 RPM spindle.
