Name
Description
[27]
Torque limit & stop
Use for performing a coasted stop in a torque limit condition. If the drive has received a stop
signal and is in torque limit, the signal is logic 0.
[28]
Brake, no brake war
Brake is active and there are no warnings.
[29]
Brake ready, no fault
Brake is ready for operation and there are no faults.
[30]
Brake fault (IGBT)
Output is logic 1 when the brake IGBT is short-circuited. Use this function to protect the drive
if there is a fault on the brake module. Use the digital output/relay to cut out the main volt-
age from the drive.
[31]
Relay 123
Digital output/relay is activated when [0] Control Word is selected in parameter group 8-**
Comm. and Options.
[32]
Mech brake ctrl
Selection of mechanical brake control. When selected parameters in parameter group 2-2* Me-
chanical Brake are active. The output must be reinforced to carry the current for the coil in the
brake. Usually solved by connecting an external relay to the selected digital output.
[33]
Safe stop active
N O T I C E
This option is only available in FC 302.
Indicates that the Safe Torque Off on terminal 37 has been activated.
[35]
External interlock
[36]
Control word bit 11
Activate relay 1 by control word from fieldbus. No other functional impact in the drive. Typi-
cal application: Controlling auxiliary device from fieldbus. The function is valid when [0] FC
profile in parameter 8-10 Control Word Profile is selected.
[37]
Control word bit 12
N O T I C E
This option is only available in FC 302.
Activate relay 2 by control word from fieldbus. No other functional impact in the drive. Typi-
cal application: Controlling auxiliary device from fieldbus. The function is valid when [0] FC
profile in parameter 8-10 Control Word Profile is selected.
[38]
Motor feedback error
Failure in the speed feedback loop from motor running in closed loop. The output can even-
tually be used to prepare switching the drive in open loop in an emergency case.
[39]
Tracking error
When the difference between calculated speed and actual speed in parameter 4-35 Tracking
Error is larger than selected, the digital output/relay is active.
[40]
Out of ref range
Active when the actual speed is outside the settings in parameter 4-52 Warning Speed Low to
parameter 4-55 Warning Reference High.
[41]
Below reference, low
Active when the actual speed is below speed reference setting.
[42]
Above ref, high
Active when actual speed is above speed reference setting.
[43]
Extended PID Limit
[45]
Bus ctrl.
Controls digital output/relay via bus. The state of the output is set in parameter 5-90 Digital &
Relay Bus Control. The output state is retained in the event of bus timeout.
[46]
Bus ctrl, 1 if timeout
Controls output via bus. The state of the output is set in parameter 5-90 Digital & Relay Bus
Control. If a bus timeout occurs, the output state is set high (on).
