7.2.4 Pulse Inhibition Function
Pulse inhibition function use external input X10 in digital pulse position mode. When external input X10 is
triggered, it will enforce the drive to stop receiving pulses input from any source, and stop the servo motor
immediately.
In factory default mode, this function is disabled. It can be set via M2 servo suite or P-65 (MI) directly from
the drive.

Software Configuration

7.2.5 Electronic Gearing Ratio
Electronic gearing ratio using the host command pulse count per revolution times the electronic gearing
ratio set on drive to set the actual rotatory pulse per revolution. This feature allows more freedom and
setting options when certain pulse count or moving counter is required
If motor pulse per revolution is 10000 pulse/rev and the electronic gearing ratio is set to 1. In this case, if
host computer send 10000 pulse, the motor will turn 1 revolution. If the electronic gearing ratio is set to
1/2, then motor will only move for 1 pulse position, when host send 2 pulses. i.e. 20000 pulses for 1 motor
revolution. In some cases, reasonable electronic gearing ratio can simplify the calculation for the host
when send pulse command.
