11.7.5 I-Portion / I-Limit
Integral step: setting range 1 … 1000
General:
An I-controller (integrating controller) determines the output value by integrating the control deviation with
weighting by the reset time. A continuous control deviation therefore leads to a further increase of the control
output. The reset time determines how large this time influence is. The maximum reset value is limited by the I-
limit. The step response of the I-component is a linear increase. This means that with a constant control devia-
tion, the integral increases and thus this component increases.
P40T:
In case of control deviation, the analog control voltage is increased stepwise until the target/actual difference
equals zero or until the I-limit set in the register is reached. The larger the I-component, the slower becomes the
control loop.
11.7.6 D-Portion
Differential voltage: setting range 1 … 1000
General:
The D-controller (differential controller) determines the output value from the time derivative of the control devia-
tion.
P40T:
In case of control deviation, a short voltage pulse proportional to the rate of change is output in order to com-
pensate this quickly - without permanently endangering the control loop stability. The level of the voltage pulse is
set (max. ± 10 V).
11.7.7 Manual Fast
Here the fast speed can be set for moving the axes in manual mode.
11.7.8 v Ref. Mode Part 1
Here the reference run speed of the back gauge until reaching the initiator is defined.
11.7.9 Manual Slow
Here the slow speed can be set for moving the axes in manual mode.
11.7.10 v Ref. Mode Part 2
Here the reference run speed of the back gauge until reaching the index pulse is defined.
11.7.11 U<<< / U>>>
This register is used to set the voltage during fast speed operation backwards / forwards.
