Use in performing a coast stop and in
torque limit condition. If the frequency
converter has received a stop signal and
is at the torque limit, the signal is logic 0.
The brake is active and there are no
warnings.
The brake is ready for operation and
there are no faults.
The output is logic 1 when the brake
IGBT is short-circuited. Use this function
to protect the frequency converter if
there is a fault on the brake modules. Use
the output/relay to cut out the mains
voltage from the frequency converter.
The relay is activated when [0] Control
Word is selected in parameter group 8-**
Communications and Options.
Enable control of an external mechanical
brake. See parameter group 2-2*
Mechanical Brake for more details.
This option is active when the actual
speed is outside the settings in
parameter 4-52 Warning Speed Low to
parameter 4-55 Warning Reference High.
This option is active when the actual
speed is below the speed reference
setting.
This option is active when the actual
speed is above the speed reference
setting.
Control output via fieldbus. The state of
the output is set in parameter 5-90 Digital
& Relay Bus Control. The output state is
retained in the event of fieldbus timeout.
Control output via fieldbus. The state of
the output is set in parameter 5-90 Digital
& Relay Bus Control. When bus timeout
occurs, the output state is set high (On).
See parameter group 13-1* Comparators. If
comparator 0 is evaluated as true, the
output goes high. Otherwise, it is low.
See parameter group 13-1* Comparators. If
comparator 1 is evaluated as true, the
output goes high. Otherwise, it is low.

Output A The output goes high whenever the
smart logic action [38] Set dig. out. A high
is executed. The output goes low
whenever the smart logic action [32] Set
dig. out. A low is executed.
[81] SL Digital See parameter 13-52 SL Controller Action.
Output B The input goes high whenever the smart
logic action [39] Set dig. out. B high is
executed. The input goes low whenever
the smart logic action [33] Set dig. out. B
low is executed.
[82] SL Digital See parameter 13-52 SL Controller Action.
Output C The input goes high whenever the smart
logic action [40] Set dig. out. C high is
executed. The input goes low whenever
the smart logic action [34] Set dig. out. C
low is executed.
[83] SL Digital See parameter 13-52 SL Controller Action.
Output D The input goes high whenever the smart
logic action [41] Set dig. out. D high is
executed. The input goes low whenever
the smart logic action [35] Set dig. out. D
low is executed.
