Monitor devices and the servo amplifier status
The relationship between related command devices, monitor devices and the servo amplifier status is shown below. Refer to
the following for details on servo amplifier LED display and each status.
Servo amplifier Instruction Manual
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 in the operation cycle during the servo OFF status (including servo OFF by servo
error).
The follow-up process is performed during "servo OFF" and SSCNET(/H) communication.
