5. Spindle Adjustment
5 - 41
[3] Adjustment of position loop gain deceleration rate
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 end detector, adjust SP002
(PGE). Adjust SP006 (CSP) after adjusting SP001 and PS002. When performing coil change
over, each coil can be adjusted individually. (Refer to the next page.)

State
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 deceleration rate for each gear by
SP107 (CSP2) to SP109 (CSP4) 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
the speed clamp value (SP005) as described later.

The orientation time will be shorter when the value is increased,
and the servo rigidity will increase. On the other hand, the
vibration will increase, and the machine will sway easily.

As the set value is larger, the orientation time becomes shorter.
However, the machine becomes likely to overshoot.

mode
Set the deceleration rate in orientation mode corresponding to
the gear 001.
When this parameter is set to "0", same as SP006 (CSP).

Set the deceleration rate in orientation mode corresponding to
the gear 010.
When this parameter is set to "0", same as SP006 (CSP).

SP109 CSP4 Deceleration rate 4
in orientation control
mode
Set the deceleration rate in orientation mode corresponding to
the gear 011.
When this parameter is set to "0", same as SP006 (CSP).

POINT
On machines with large spindle-to-motor gear ratios, it may not be possible to
achieve the desired results by adjusting the SP001, SP002, and SP006 parameters,
due to internal clamping. When clamped, the parameter settings can be changed, but
control remains unchanged.
