Description: Displays the I2t value for the voltage limiting chopper 1 for Converter Commutation Protector (CCP).
Description: Displays the I2t value for the voltage limiting chopper 2 for Converter Commutation Protector (CCP).
Description: Sets the upper response threshold of the voltage limiter implemented in the CCP.
During the turn-off operation of the CCP when reducing the armature current, this limits the counter voltage that is
created - and which is also necessary - to a non-hazardous value for the basic device and for the associated CCP.
Note: CCP: Converter Commutation Protector
The parameter is set automatically during the "optimization run for CCP" (p50051 = 30).
The correct setting of this parameter can be taken from the following reference:
SIMOREG CCP Operating Instructions
Description: Sets the minimum charging voltage required for the turn-off capacitors used in the CCP to successfully turn off the
thyristors.
This value is used as setpoint for the two-level controller, which precharges the turn-off capacitors from the line
supply.
The maximum pre-charging voltage that can be reached is limited by the average rectified value of the line voltage
that is actually connected.

The parameter is set automatically during the "optimization run for CCP" (p50051 = 30).
