53
Drive Ramp Rslt
Displays the speed reference value, after the limit function. This is the input to the error
calculator and speed regulator. Available for use in peer-to-peer data links (DPI interface).
This number is scaled so that rated motor speed will read 32768.

Speed Comp
Displays the derivative or change in Par 56 [Inertia SpeedRef] on a per second basis. Link
this parameter to Par 23 [Speed Trim 3] and set Par 24 [SpeedTrim 3 Scale] to 0.002 to
reduce position error in following applications.

Inertia SpeedRef
The speed input of the inertia compensator. Link this parameter to the output of an internal
ramp or s-curve block. The inertia compensator generates a torque reference that is
proportional to the rate of change of speed input and total inertia.
