(2) For output division ratio setting
Set parameter No. PC13 to " 1 ".
The number of pulses per servo motor revolution is divided by the set value.
Output pulse=
Resolution per servo motor revolution

For instance, when parameter No. PA15 is set to "8", the A/B-phase pulses actually output are as indicated
below.

Set division ratio by parameter No. PA15.
(3) When outputting pulse same as command pulses
Set parameter No. PC13 to " 2 ". The feedback pulses from the encoder can be output after being
converted to the same value as the command pulse.
