Operating Instructions
Function:
of the motor. If the motor is not
rotating, the output follows the
reference.
Active communication (no time-out)
via the serial communication port.
frequency converter in torque limit
condition. If the frequency converter
has received a stop signal and is in
torque limit, the signal is Logic '0.'
Brake is active and there are no
warnings.
Brake is ready for operation and there
are no faults.
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 module. Use the digital output/
relay to cut out the main voltage
from the frequency converter.
Digital output/relay is activated when
Control Word [0] is selected in
parameter group 8-** Communication
and Options..
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. Solved by
connecting an external relay to the
selected digital output.
(FC 302 only) Indicates that the safe
stop on terminal 37 has been
activated.
Activate relay 1 via control word from
fieldbus. No other functional impact
in the frequency converter. Typical
application: Controlling auxiliary
devices from fieldbus. The function is
valid when [0] FC profile in
8-10 Control Word Profile is selected.
Activate relay 2 (FC 302 only) by
control word from fieldbus. No other
functional impact in the frequency
converter. Typical application:

[40] Out of ref range Active when the actual speed is
outside settings in 4-52 Warning
Speed Low to 4-55 Warning Reference
High.
[41] Below reference, Active when actual speed is below
low speed reference setting.
[42] Above ref, high Active when actual speed is above
speed reference setting.
[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. If 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. If bus time-out the
output state is set to low (Off).
[51] MCO controlled Active when an MCO 302 or MCO
305 is connected. The output is
controlled from an option.
[60] Comparator 0 See parameter group 13-1* Smart
Logic Control. If Comparator 0 in SLC
is true, the output goes high.
Otherwise, it is low.
