B00: FALSE = Open MCB, TRUE = PreCharge DC
Open MCB: Opens MCB if closed, stops precharging if charging is active trough the drive.
PreCharge DC: Drive will start precharge if function activated by digital output and control place is
fieldbus. When control place is not fieldbus precharging is started from normal start command.
B01: MCB Close Enable
FALSE: MCB Closing is disabled in fieldbus control. MCB Remains open when if DC voltage is above
closing limit.
TRUE: MCB Closing is enabled in fieldbus control. This bit can be true all the time if function is not
needed.
B02: Quick Stop
FALSE: Drive will stop modulation immediately and open MCB immediately.
TRUE: Quick stop is not active and normal operation is possible.
B03: FALSE = Stop Request, TRUE = Start Request
Stop Request: Drive will stop .
Start Request: Start Command to the drive. Rising edge needed for start.
B04: Output Power Limit to Zero
FALSE: Output power limit is reduced to 7 % if parameter limit is higher.
TRUE: Power limit is defined by power limit parameters.
B05: Disable Power Increase. Input or Output
FALSE:
TRUE: Power limit is defined by power limit parameters.
B06: Input Power Limit to Zero
FALSE: Input power limit is reduced to 7 % if parameter limit is higher
TRUE: Power limit is defined by power limit parameters.
B07: FALSE = No significance, TRUE = Fault Acknowledge
Fault Acknowledge: The group signal is acknowledged with a positive edge.
B08: FALSE = No Function, TRUE = DC Ref 1
B09: FALSE = No Function, TRUE = DC Ref 2
DC Ref FB Reference
B08 FALSE
B09 FALSE
B10: FALSE = FB Control disabled TRUE = FB Control Enabled
FB Control Disabled: Drive will not follow main control word from Fieldbus. If removed while
running drive will make coasting stop.
FB Control Enabled: Drive follows control word from fieldbus
B11: FALSE = FB WD Pulse Low, TRUE = FB WD Pulse High
Watch dog pulse: This pulse is used to monitor that PLC is alive. If pulse is missing drive will go to
fault state. This function is activated by P2.7.6 FB WD Delay. When value is zero pulse si not
monitored.
