6.2.2 Accumulated pulse setting
Select the maximum accumulated pulse amount that can be counted in the deviation counter.
(1) Calculating accumulated pulse amount
When a servomotor is used, "maximum accumulated pulse amount" obtained by the following formula generates.
Configure this setting so that "maximum accumulated pulse amount" stays within the accumulated pulse setting
range.
(a) Position loop gain
Position loop gain is a parameter to be set on the servomotor side. It effects operation in case of a servomotor
stop and pulse amount in the deviation counter during operation.
Position loop gain is adjusted to 20 to 30s
-1
normally. Make fine adjustment if necessary.
For details, refer to the manual for the servomotor.
Position loop gain value Description
Low Accumulated amount is large, and adjustment time at a stop becomes long.
High Overshoot becomes large at a stop, or vibration tends to occur during a stop.
