Default setting (_:115) T1 delay = 40 s
You can adjust the control action so that the smallest number of adjusting commands possible is necessary. To
do this, using T1 characteristic, you set the control response and, using T1 delay, you set a time
delay.
In the Linear setting (linear control response), the control response is independent of the voltage deviation.
A constant time delay applies here.
In the Inverse setting (inverse control response), the time delay is a function of the voltage deviation refer-
enced to Target voltage 1. The greater the control deviation, the faster the control response. The control
quality improves, but the switching frequency increases. The effective time delay results from:
