38 *ENR
Used to set the encoder pulses (A-phase, B-phase) output by the
enhancing IO unit.
Set the value 4 times greater than the A-phase and B-phase pulses.
You can use DRU parameter No.33 to choose the output pulse
setting or output division ratio setting.
The number of A-phase and 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 DRU parameter No.33.
Set the number of pulses per servo motor revolution.
Output pulse set value [pulses/rev]
At the setting of 5600, for example, the actually output A-phase
and B-phase pulses are as indicated below:
4
5600
A-phase and B-phase output pulses 1400[pulse]
For output division ratio setting
Set "1 " in DRU parameter No.33.
The number of pulses per servo motor revolution is divided by the
set value.
