5-40 Function Relay
Array [9]
(Relay 1 [0], Relay 2 [1], Relay 3 [2] (MCB 113), Relay 4 [3] (MCB
113), Relay 5 [4] (MCB 113), Relay 6 [5] (MCB 113), Relay 7 [6]
(MCB 105), Relay 8 [7] (MCB 105), Relay 9 [8] (MCB 105))
Option:
Function:
There is no over-temperature
warning.
[24]
Ready, Voltage OK
Frequency converter is ready for
operation and the mains voltage is
within the specified voltage range
(see General Specifications section in
Design Guide).
[25]
Reverse
Logic ‘1’ when CW rotation of the
motor. Logic ‘0’ when CCW rotation
of the motor. If the motor is not
rotating the output will follow the
reference.
[26]
Bus OK
Active communication (no time-out)
via the serial communication port.
[27]
Torque limit & stop
Use in performing a coasted stop
and 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’.
[28]
Brake, no brake war 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 fault (IGBT)
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.
[31]
Relay 123
Digital output/relay is activated
when Control Word [0] is selected in
parameter group 8-**.
[32]
Mech brake ctrl
Selection of mechanical brake
control. When selected parameters in
parameter group 2-2* 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
(FC 302 only) Indicates that the safe
stop on terminal 37 has been
activated.

(MCB 105), Relay 8 [7] (MCB 105), Relay 9 [8] (MCB 105))
Option:
Function:
[36]
Control word bit 11 Activate relay 1 by control word
from fieldbus. No other functional
impact in the frequency converter.
Typical application: controlling
auxiliary device from fieldbus. The
function is valid when FC profile [0]
in
is
selected.
[37]
Control word bit 12 Activate relay 2 FC 302 only) by
control word from fieldbus. No other
functional impact in the frequency
converter. Typical application:
controlling auxiliary device from
fieldbus. The function is valid when
FC profile [0] in
is selected.
[38]
Motor feedback
error
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 emergency case.
[39]
Tracking error
When the difference between
calculated speed and actual speed in
is larger than
selected the digital output/relay is
active.
[40]
Out of ref range
Active when the actual speed is
outside settings in
to
[41]
Below reference,
low
Active when actual speed is below
speed reference setting.
[42]
Above ref, high
Active when actual speed is above
speed reference setting.
[43]
Extended PID Limit
[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 timeout Controls output via bus. The state of
the output is set in
. In the event of bus
time-out 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
