Set the value 4 times greater than the A-phase or B-phase pulses.

You can use parameter No. 54 to choose the output pulse setting or

output division ratio setting.

The number of A/B-phase pulses actually output is 1/4 times greater

than the preset number of pulses.

The maximum output frequency is 1.3Mpps (after multiplication by

4). Use this parameter within this range.

For output pulse designation

Set "0

" (initial value) in parameter No. 54.

Set the number of pulses per servo motor revolution.
