Type: Float, Status Variable, Read-Only.
Units: RPM
Range: -48,000 to +48,000 for resolver
-30,000 to +30,000 for encoder
Default: none
Purpose: Instantaneous value of the velocity feedback.
Guidelines: For normal operation, RemoteFB = 0 or 1, VelFB is the resolver velocity. For RemoteFB = 2 VelFB is based on delta EncPos at position loop update rate.
