3) Adjust the orientation time and vibration. Refer to the following table and adjust the parameters
according to the apparent state. When using the motor PLG and magnetic sensor, adjust the
position loop gain with SP001 (PGM). When using the spindle encoder, adjust SP002 (PGE).
Adjust SP006 (CSP) after adjusting SP001 and PS002.

SP001/SP002 SP006
The operation overshoots when stopping Decrease the setting value Decrease the setting value
The orientation time is long Increase the setting value Increase the setting value
Hunting occurs when stopping Decrease the setting value Do not change the setting value
An excessive error alarm occurs Decrease the setting value Decrease the setting value
To adjust the shortest orientation time for each gear, adjust SP107 (CSP2) to SP109 (CSP4) in
the same manner for each gear. When using a coil changeover, adjust the shortest orientation
time for each coil by adjusting SP119 (MPGH) to SP122 (MPCSL) in the same manner. If an
excessive error alarm occurs when the gear ratio is 1:10 or more, and the state is not improved
with the above adjustments, adjust SP005 (OSP).

position loop gain
As the set value is larger, the orientation time becomes
shorter and servo rigidity is increased.
However, vibration is increased and the machine
becomes likely to overshoot.
