Function:
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.
(FC 302 only) Indicates that the Safe
Torque Off on terminal 37 has been
activated.
fieldbus. No other functional impact
in the frequency converter. Typical
application: controlling auxiliary
device from fieldbus. The function is
valid when [0] FC profile in
8-10 Control Word Profile is selected.
control word from fieldbus. No other
functional impact in the frequency
converter. Typical application:
controlling auxiliary device from
fieldbus. The function is valid when
[0] FC profile in 8-10 Control Word
Profile is selected.
Failure in the speed feedback loop
from motor running in closed loop.
The output can eventually be used to
prepare switching the frequency
converter in open loop in emergency
case.
When the difference between
calculated speed and actual speed in
4-35 Tracking Error is larger than
selected the digital output/relay is
active.
Active when the actual speed is
outside settings in 4-52 Warning
Speed Low to 4-55 Warning Reference
High.
Active when actual speed is below
speed reference setting.
Active when actual speed is above
speed reference setting.

Option: Function:
[45] Bus ctrl. Controls digital output/relay via bus.
The state of the output is set in
5-90 Digital & Relay Bus Control. The
output state is retained in the event
of bus time-out.
[46] Bus ctrl, 1 if Controls output via bus. The state of
timeout the output is set in 5-90 Digital &
Relay Bus Control. In the event of bus
time-out, the output state is set high
(On).
[47] Bus ctrl, 0 if Controls output via bus. The state of
timeout the output is set in 5-90 Digital &
Relay Bus Control. In the event of bus
time-out, the output state is set low
(Off).
[51] MCO controlled Active when an MCO 302 or MCO
305 is connected. The output is
controlled from option.
[60] Comparator 0 See parameter group 13-1*
Comparators. If Comparator 0 in SLC
is TRUE, the output goes high.
Otherwise, it is low.
[61] Comparator 1 See parameter group 13-1*
Comparators. If Comparator 1 in SLC
is TRUE, the output goes high.
Otherwise, it is low.
[62] Comparator 2 See parameter group 13-1*
Comparators. If Comparator 2 in SLC
is TRUE, the output goes high.
Otherwise, it is low.
[63] Comparator 3 See parameter group 13-1*
Comparators. If Comparator 3 in SLC
is TRUE, the output goes high.
Otherwise, it is low.
[64] Comparator 4 See parameter group 13-1*
Comparators. If Comparator 4 in SLC
is TRUE, the output goes high.
Otherwise, it is low.
[65] Comparator 5 See parameter group 13-1* Smart
Logic Control. If Comparator 5 in SLC
is TRUE, the output goes high.
Otherwise, it is low.
[70] Logic rule 0 See parameter group 13-4* Smart
Logic Control. If Logic Rule 0 in SLC is
TRUE, the output goes high.
Otherwise, it is low.
