No. Name and function
6 Number of feedback pulses
Set the number of pulses per revolution according to
controller side command. Information on the servo motor
such as number of feedback pulses, current location, droop
pulses, and position within one-revolution can be obtained
by the value converted to the number of feedback pulses for
the corresponding setting value.
