1 Set limit value for overvoltage
V>
6 V
actual
: Measured voltage
2 + B %: Upper limit A Value exceeds limit value
3 V
desired
: Desired value B Value falls below limit value
4 - B %: Lower limit C High-speed return is started
(lower tap-change)
5 Set switching pulse time
If you activated the overvoltage blocking, all switching pulses to the motor-
drive unit are blocked when a limit value is exceeded. At the same time, the
red LED U> lights up and the Overvoltage U> message is displayed. As
soon as the measured voltage U
actual
has again fallen below the limit value,
blocking and the message are reset.
The following sections describe how you can set the parameters for the
overvoltage U> limit value.
Setting overvoltage U> as %
The limit value is entered as a relative value (%) of the set desired value. To
set the limit value, proceed as follows:
