CE65
PID target value acceleration/
deceleration time
0.025.5 0.0sec X
Description: Set PID target value acceleration/ deceleration time, set time to accelerate from 0 to 100%.
When needed PID target value is the smooth curve not P.W.M. wave when used.
Notice: Due to PID output will pass by acceleration/ deceleration of Cd8, 9. If mechanical quassation was
caused by setting CE65 and acceleration/ deceleration. User can reduce constant to avoid quassation.

01 0 X
CE67
PID delay position
selecting
01 0 X
Description: Use CE66 to select position of P controller.
P、I、D controllers were divided to indivdual controller when set setting value to 0.
P controller is located in front of I、D controllers when set setting value to 1. (enter I、D controller after error
passed by P controller).
Use CE67 to select PID delay position.
PID output delay when setting value is 0.
D controls output dealy when setting value is 1.
◆Selet step of I controller reset
Constant No. Constant name Settable range Factory setting
Change during
operation
CE68 Select I control reset 01 0 X
Description:Setting value is 0, clear I control Integral value when place stop command or place reset command.
Setting value is 1, clear I control Integral value when only place reset command.
Reset command must be controlled by multi-functions input terminal (set multifunctions input Cd92 97 to 12).
