Dead band Xtot
DEAD_BAND
Default:
Dead band of the control characteristic
in the range of 0.1 to 10.0 % of the rated travel/nominal angle
0.5 %
Delay time
DELAY_TIME (M)
Default:
Reset criterion for monitoring the active control loop. When the entered delay time
DELAY_TIME is exceeded and the system deviation is not within the limits of the
entered tolerance band TOLERANCE_BAND, a control loop error is reported.
0 to 240 s.
The delay time is determined from the min. transit time during initialization and can
be adapted.
10 s
Derivative-action coefficient KD
SERVO_RATE
Range:
Default:
Gain factor of the derivative element. We recommend increments of 0.02 when
adapting the value. Higher increments cause an increased deceleration before
reaching the reference variable.
0.0 to 1.00
0.12
