Profile 2 (2 x 16 bit): Outputs (Control)
Table 193. Profile 2: Output bytes 0 and 4
Byte Bit Designation Meaning
0
0OnOff
On/Off
0: Normal stop (with configured ramp time)
1: Operation
This bit needs to be toggled once in order to start operation. This bit will not start or stop the device during normal operation
1Off2
Run-down (Coast Stop: Off 2)
0: Coast stop (switch off output voltage)
1: no free run-down
If this bit has a value of 0, the variable frequency drive is coasting and the output is de-energized.
If it has a value of 1, the variable frequency drive is running normally. This bit will not start or stop the device during
normal operation.
2Off3
Quick Stop: Off3
0: Quick stop (shortest ramp)
1: no quick stop
If this bit has a value of 0, the device will be stopped with a quick stop with the shortest ramp time.
If it has a value of 1, the variable frequency drive is running normally. This bit will not start or stop the device during
normal operation.
3EN_Op
Operation released
0: Stop
1: Operation
If this bit has a value of 0, the variable frequency drive will stop.
If it has a value of 1, the variable frequency drive’s output will be enabled. This bit will start and stop the device
during normal operation.
4EN_Ramp
Release ramp (Enable Ramp Generator)
0: Reset ramp (set point value = 0)
1: Release ramp
If this bit has a value of 0, the variable frequency drive will remain stopped; the output will not be switched off. If it has a value of
1, the ramp enable signal will be activated and the device will start with the set ramp.
5Unfreeze
Unfreeze ramp
0: Freeze ramp (the ramp generator’s current output value will be frozen)
1: Do not freeze ramp
If this bit has a value of 0, the variable frequency drive 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 set point change.
If the bit has a value of 1, the device will continue running along the set ramp all the way to the frequency set point.
6EN_Set
Enable Setpoint
EN_Set enables the set point value and starts or stops the motor with the ramp function.
0: Do not activate set point value
1: activate set point value
If this bit has a value of 0, the variable frequency drive will not receive a set point and will remain at the minimum frequency;
the output will not be switched off. If it has a value of 1, the set point will be activated.
7FaultAck
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. The fault acknowledge function will only respond
to a rising edge, i.e., to the value changing from 0 to 1.
