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.
Adjustment of desired voltage value dependent on active power
You can use these parameters to set an active power-dependent adjustment
of the desired voltage value. The desired value [
► 67] you have set will be
adjusted automatically depending on the active power measured. This func-
tion is used to compensate for a voltage drop during increased load or an in-
crease in voltage due to a decentralized feed-in.
Depending on whether positive or negative active power is measured, the
desired value calculation is based on 2 linear equations (see example in dia-
gram below).
