1 to 65535
POINT
This parameter is made valid when power is switched off, then on after
setting.
Used to set the encoder pulses (A-phase, B-phase) output by the servo amplifier.
Set the value 4 times greater than the A-phase or B-phase pulses.
You can use parameter No.PC19 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 4.6Mpps (after multiplication by 4). Use this parameter within this range.
(a) For output pulse designation
Set "
0 " (initial value) in parameter No.PC19.
Set the number of pulses per servo motor revolution.
Output pulse
set value [pulses/rev]
For instance, set "5600" to Parameter No.PA15, the actually output A/B-phase pulses are as indicated
below.

5600
A B-phase output pulses 1400[pulse]
(b) For output division ratio setting
Set "
1 " in parameter No.PC19.
The number of pulses per servo motor revolution is divided by the set value.
