Detailed Drive Operation Chapter 1

The inertia compensation outputs the calculated torque to the parameter 59
[Inertia Trq Add]. [Inertia Trq Add] is summed with the output of the friction
compensation block and the torque generated by the speed reference loop. That
summed torque enters the torque selection block (refer to

Torque Reference on

page 193

for more information).

Parameter 55 [Speed Comp] contains the rate of acceleration or deceleration
calculated in the inertia compensation block. This parameter is used in following
applications. Link parameter 23 [Speed Trim 3] to [Speed Comp] and set
parameter 24 [SpdTrim 3 Scale] to 0.002 to reduce position error in following
applications.
