Function
[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
[0] Control Word
is selected in

Options
.
[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.

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).
[50]
On reference
Active when a VLT® Advanced Cascade Controller MCO 102 or VLT® Motion Control MCO 305 is
connected. The output is controlled from the option.
[51]
MCO controlled
Active when a VLT® Advanced Cascade Controller MCO 102 or VLT® Motion Control MCO 305 is
connected. The output is controlled from the option.

Comparator 0
See
parameter group 13-1* Comparators
. If comparator 0 is evaluated as true, the output goes high.
Otherwise, it is low.
[61]
Comparator 1
See
parameter group 13-1* Comparators
. If comparator 1 is evaluated as true, the output goes high.
Otherwise, it is low.
[62]
Comparator 2
See
parameter group 13-1* Comparators
. If comparator 2 is evaluated as true, the output goes high.
Otherwise, it is low.
