OK definitely some confusion here...

Servo controller is nothing to do with VFD. VFD is standard 0 - 10v speed and FWD/REV run/stop inputs and can be driven from normal spindle control board or BOB with 0 - 10v speed control output.


Servo controller can be programmed to operate in different modes - parameter Pn002. One of these modes is step/direction for positional control (like a stepper) using wiring diagram 2.3.1. Another mode is analogue speed or torque control using wiring diagram 2.3.2. These modes are mutually exclusive, you can use one or the other but not both.

@vre: what are you using servos for?
