Function
[18]
Out of feedb. range
Feedback is below the limit set in
parameter 4-56 Warning Feedback Low
and
parameter 4-57
Warning Feedback High
.
19
Below feedback, low
Feedback is below the limit set in
parameter 4-56 Warning Feedback Low
.
[20]
Above feedback,
high
Feedback is above the limit set in
parameter 4-57 Warning Feedback High
.
[21]
Thermal warning
The thermal warning turns on when the temperature exceeds the limit in the motor, the drive,
the brake resistor, or the thermistor.
[22]
Ready, no thermal W
The drive is ready for operation, and there is no overtemperature warning.
[23]
Remote, ready, no
TW
The drive is ready for operation and is in auto-on mode. There is no overtemperature warning.
[24]
Ready, voltage OK
The drive is ready for operation and the mains voltage is within the specified voltage range.
[25]
Reverse
The motor runs (or is ready to run) clockwise when logic = 0 and runs counterclockwise when
logic = 1. The output changes when the reversing signal is applied.
[26]
Bus OK
Active communication (no timenout) via the serial communication port.
[27]
Torque limit & stop
Used for coast stop and in torque limit conditions. If the drive has received a stop signal and is at
the 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 modules. To cut out the main voltage from the drive, use the output/
relay.

Relay 123
Relay is activated when

[32]
Mech brake ctrl
Enables control of an external mechanical brake. For more information on mechanical brake con-
trol, refer to the drive-specific design guide.
[33]
Safe stop active
Indicates that the Safe Torque Off on terminal 37 is activated.
[35]
External interlock
[38]
Motor feedback error
[40]
Out of ref range
Active when the actual speed is outside settings in
parameter 4-52 Warning Speed Low
in
parame-
ter 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 the actual speed is above speed reference setting.
[43]
Extended PID limit
[45]
Bus ctrl.
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 retained.
[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).
[47]
Bus ctrl, 0 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 low (off).
