Module 9166 Read momentary utilization of drive motor
The module provides the momentary utilization of a drive motor controlled by
the integral current controller in percent (%) of the rated utilization. The
momentary utilization is ascertained by the current controller, under
consideration of the equivalent circuit data of the motor.
In the speed range (n actl) < (n noml) utilization refers to the quotient |M/
Mlimit|, in the range (n actl) >= (n noml) utilization refers to the quotient |P/
Plimit|.
Constraints:
The value 0 is read for axes that are not connected.
The spindle must be coded as axis 15.
An axis that is not configured as "active", or an axis that was set to the
"deactivated axis" activation status (e.g. with Module 9226 or 9418), is
treated as if it were not present.
Possible errors:
The control is not equipped with a current controller.
