P2.5.7.4 DC Supervision Limit
This parameter defines when FB Status Word B10 is high (ID68). The Bit is high when DC
voltage is above the value set by this parameter.
P2.5.7.5 CB Close Mode
This parameter defines how the closing of circuit breaker is handled.
0 = DC Voltage
Normal AFE operation type circuit breaker control. The circuit breaker is closed when
DC voltage is at a required level.
1 = DC Voltage or Start Command
The circuit breaker is closed when DC voltage is at the required level, or from a start
command if DC is at a required level. This can be used when the breaker is opened,
for example, by a stop command but DC remains high. It is useful when used in a
battery system.
2 = Start Command
The circuit breaker is closed from a start command if DC is at a required level.
P2.5.7.6 MCB At Stop Command
The parameter defines the action for MCB when a stop command has been given.
0 = Keep closed
1 = Open CB when drive has stopped
P2.5.7.7 MCB close delay
The parameter defines the delay when RO2 is closed after the drive has determined that
MCB can be closed.
