Setting delay time T2
With this parameter, you can set delay time T2. Delay time T2 is used to
compensate for large control deviations faster.
The delay time T2 only takes effect if more than one tap-change operation is
required to return the voltage to within the set bandwidth. 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 con-
trol 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.
To set the delay time T2, proceed as follows:
1. > Parameter > Control parameter > Press until the de-
sired parameter is displayed.
ð Delay time T2.
2. Press to increase the time or to reduce it.
3. Press .
ð The delay time T2 is set.
Activating/deactivating delay time T2
To activate/deactivate delay time T2 , proceed as follows:
1. > Parameter > Control parameter > Press until the
desired parameter is displayed.
ð T2 activation.
2. Press or to activate/deactivate T2.
3. Press .
ð The delay time T2 is activated/deactivated.
Limit values
In the Limit values menu item, you can set all the parameters needed for lim-
it value monitoring as relative or absolute values. You can set three limit val-
ues:
▪
Undervoltage V<
▪ Overvoltage V>
▪ Overcurrent I>
