The delay time T2 only takes effect if more than one tap-change operation is
required to correct the control deviation. The first output pulse occurs after
the set delay time T1. After the set tap-change delay time T2 has elapsed,
additional pulses occur in order to correct the existing control deviation.
The following requirements must be noted to set delay time T2:
▪
The delay time T2 must be greater than the switching pulse time.
▪ The delay time T2 must be greater than the maximum operating time of
the motor-drive unit.
▪ The delay time T2 must be less than the value set for delay time T1.
Behavior with delay times T1 and T2
Delay time T2 can be used to correct major control deviations more quickly.
Ensure that you set a lower value in the "Delay time T2" parameter than in
the "Delay time T1" parameter.
If the measured voltage U
actual
deviates from the set bandwidth for a long
period , a control impulse is output to the motor-drive unit after the set de-
lay time T1 . If the measured voltage U
actual
is still outside the bandwidth,
