PNU Description
p51577 CCP chopper voltage setpoint, upper response threshold /
CCP V_set thresh up
Description:
Sets the upper response threshold of the voltage limiter implemented in the
CCP. Within the scope of the turn-off operation of the CCP, this limits the
counter-voltage - which is also necessary - that occurs when the armature
current is reduced to a value that is not dangerous for the basic converter unit
and the associated CCP.
Note:
CCP: Converter Commutation Protector
The parameter is automatically set for the "Optimization run for CCP" (p50051
= 30).
The following table should be used to correctly set this parameter.
As a result of the unit MLFB for the basic converter unit and SIMOREG CCP,
two setting values are obtained from which the lower of the two should be set
at p51577.
Example:
Basic converter unit MLFB: 6RA8085-6DV62-0
SIMOREG CCP MLFB: 6RA7085-6FC00-0
therefore the following setting is obtained: p51577=1100 V
