6.11.10 Momentary utilization of drive motors
Module 9166 provides the momentary utilization of the given drive motor as a
percentage value. The module provides the percentage of the drive's
mechanical power output that arrives at the tool.
Utilization means:
If n
actl
= n
N
, then:
Mcurr and Pcurr are ascertained cyclically by the current controller. This is
based on the equivalent circuit data of the motor and the present motor
current.
Prated = P-N from motor.mot
Nrated = N-N from motor.mot
