6.11.9 Read Actual Utilization of Drive Motors

6 – 174
Module 9166 provides the momentary utilization of the given drive motor as a
percentage value.
Utilization means:
Speed range n
Asynchronous
motor
Synchronous motor
Instead of the drive torque, one uses the effective component I
current, which is proportional to the torque.
I is formed as mean value of the individual current values I
