N:numbers of motor rotation ; C:solutions of
photoelectric encoder in per rotation, the default
value is 2500.
4.For example, input command pulse P is 6000,
servo motor rotate a roll:
G=(N×C×4)/P=(1×2500×4)/6000=5/3, So PA-12
should be set to 5, PA-13 should be set to 3.
5.The numerator of electronic gear for command
pulse is decided by Gear1 and Gear2. The
denominator is decided by PA-13. The details as

command
pulse
1.Set the input mode of position command pulse.
2.To set one of 4 input modes:
0: Pulse+Direction.
1: CCW pulse/CW pulse.
2: phase A and phase B orthogonal input.
3: Internal position input.
Remark: CCW: observe from the motor axial
direction. It defines CCW in counter clock wise
and CW in clock wise.

The rang of
positioning
completion
1.Setting the pulse range of positioning
completion in position control mode.
2.
The drive judges whether it has finished
positioning completion based on this parameter.
When the rest pulses in position deviation counter
are less than or equal with the setting value, the
COIN
(
positioning completion) of digital
output(DO) is ON, or else OFF
