Function
[21]
Thermal warning
Thermal warning turns on when the temperature exceeds the limit either in motor, drive, brake resis-
tor, or connected 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 counterclockwise when logic=1. The
output changes when the reversing signal is applied.
[26]
Bus OK
Active communication (no timeout) 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 in
torque limit, the signal is logic 0.
[28]
Brake, no brake
war
The 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 faults (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 voltage 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* Mechanical
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
Indicated that the Safe Torque Off on terminal 37 has been activated.
[36]
Control word bit
11
Activate relay 1 by control word from fieldbus. No other functional impact in the drive. Typical appli-
cation: Controlling auxiliary device from fieldbus. The function is valid when
[0] FC profile
in
parame-
ter 8-10 Control Word Profile
is selected.
[37]
Control word bit
12
Activate relay 2 by control word from fieldbus. No other functional impact in the drive. Typical appli-
cation: Controlling auxiliary device from fieldbus. The function is valid when
[0] FC profile
in
parame-
ter 8-10 Control Word Profile
is selected.
[38]
Motor feedback er-
ror
Failure in the speed feedback loop from motor running in closed loop. The output can eventually be
used to prepare switching the drive in open loop in an emergency case.
[39]
Tracking error
When the difference between the calculated speed and the actual speed in
parameter 4-35 Tracking
Error
is larger than selected, the 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
parame-
ter 4-55 Warning Reference High
.
[41]
Below reference,
low
Active when the actual speed is below the speed reference setting.
[42]
Above ref, high
Active when the actual speed is above the 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 if a bus timeout occurs.
