7.5.5 DC Voltage limit parameters

P2.5.5.1 DC Voltage supervision limit
This parameter sets a supervision limit for the DC link voltage. If the voltage increases
above this, this signal goes HIGH. This signal can be connected to digital output and it is
copied to Main Status Word, Bit 10. This value does not limit the DC-link voltage but it
can be used for monitoring purposes.
P2.5.5.2 High MCB Close Limit
This parameter can be used to increase normal MCB closing level. Example case of use
is when there is high capacitance in DC-Link and closing the MCB at normal level will
cause current spike.
