Feed forward gain
Set the feed forward gain. When the setting is 100
, the droop pulses
during operation at constant speed are nearly zero. However, sudden
acceleration/deceleration will increase the overshoot. As a guideline, when
the feed forward gain setting is 100
, set 1s or more as the
acceleration/deceleration time constant up to the rated speed.

27 *ENR Encoder output pulses
Used to set the encoder pulses (A-phase or 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.54 to choose the output pulse designation 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.
