Designation
Meaning
0
0
OnOff
Switch on/off
0: Normal stop (with configured ramp time)
1: ready for operation
In the case of a High signal, the variable frequency drive enables the output if the PROFI-
drive mechanism is executed correctly.
1
Off2
Coast Stop (Coast Stop: Off 2)
0: Coast stop (switch off output voltage)
1: no coast stop
2
Off3
Quick Stop: Off3
0: Quick stop (shortest ramp)
1: no quick stop
With a value of 0, a quick stop with ramp is performed.
3
EN_Op
Operation released
0: Stop
1: Operation
With a value of 0, the variable frequency drive/variable speed starter will stop.
4
EN_Ramp
Release ramp (Enable Ramp Generator)
0: Reset ramp (setpoint = 0)
1: Enable ramp generator
With a value of 0, the variable frequency drive/variable speed starter will remain
stopped; the output will not be switched off.
With a value of 1, the ramp enable is activated and the variable frequency drive/variable
speed starter moves up with the set ramp.
5
Unfreeze
Unfreeze ramp
0: Freeze ramp (the ramp generator's current output value will be frozen)
1: Unfreeze ramp
With a value of 0, the variable frequency drive/variable speed starter will continue
running with the most recently set frequency; the output will not be switched off.
If this occurs after the ramp time elapses, this will have no effect until the next setpoint
change.
With a value of 1, the device will continue running along the set ramp all the way to the
frequency setpoint.
6
EN_Set
Enable Setpoint
EN_Set enables the setpoint value and starts or stops the motor with the ramp function.
0: Do not activate the setpoint
1: Activate the setpoint
With a value of 0, the variable frequency drive/variable speed starter will not receive a
setpoint and will remain at the minimum frequency; the output will not be switched off.
With a value of 1, the setpoint is activated.
7
FaultAck
Fault Acknowledge
0: Do not acknowledge current fault
1: Acknowledge current fault (rising edge: 0
→
1)
This bit can be used to reset a fault in the variable frequency drive/variable speed starter.
The fault acknowledge function will only respond to a rising edge, i.e., to the value chan-
ging from 0 to 1.
