Follow Up Function - Mitsubishi Electric RD77MS2 User Manual

Follow up function

Follow up function
The follow up function monitors the number of motor rotations (actual present value) with the servo OFF and reflects the value
in the present feed value.
If the servomotor rotates during the servo OFF, the servomotor will not just rotate for the amount of droop pulses at switching
the servo ON next time, so that the positioning can be performed from the stop position.
Execution of follow up
Follow up function is executed continually during the servo OFF status.

Servo ON or OFF status
The follow-up function performs the process if the "Simple Motion module and the servo amplifier is turned
