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:
[14]
Above current, high Motor current is higher than set in
4-51 Warning Current High
.
[15]
Out of speed range
Output speed/frequency is outside
the frequency ranges set in
4-52 Warning Speed Low
and
4-53 Warning Speed High
.
[16]
Below speed, low
Output speed is lower than the
setting in
4-52 Warning Speed Low
[17]
Above speed, high
Output speed is higher than the
setting in
4-53 Warning Speed High
.
[18]
Out of feedb. range Feedback is outside the range set in
4-56 Warning Feedback Low
and
4-57 Warning Feedback High
.
[19]
Below feedback, low Feedback is below the limit set in
4-56 Warning Feedback Low
.
[20]
Above feedback,
high
Feedback is above the limit set in
4-57 Warning Feedback High
.
[21]
Thermal warning
Thermal warning turns on when the
temperature exceeds the limit either
in motor, Adjustable frequency drive,
brake resistor, or connected
thermistor.
[22]
Ready,no thermal W Adjustable frequency drive is ready
for operation and there is no
overtemperature warning.
[23]
Remote,ready,no TW Adjustable frequency drive is ready
for operation and is in auto on
mode. There is no overtemperature
warning.
[24]
Ready, Voltage OK
Adjustable frequency drive is ready
for operation and the AC line
voltage is within the specified
voltage range (see General Specifi-
cations 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 timeout)
via the serial communication port.

Option:
Function:
[27]
Torque limit & stop
Use in performing a coasted stop
and Adjustable frequency drive in
torque limit condition. If the
Adjustable frequency drive 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 Adjustable
frequency drive if there is a fault on
the brake module. Use the digital
output/relay to cut out the AC line
voltage from the Adjustable
frequency drive.
[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.
[36]
Control word bit 11 Activate relay 1 by control word
from the serial communication bus.
No other functional impact in the
Adjustable frequency drive. Typical
application: controlling auxiliary
device from the serial communi-
cation bus. The function is valid
when FC profile [0] in
8-10 Control
Word Profile
is selected.
[37]
Control word bit 12 Activate relay 2 FC 302 only) by
control word from serial communi-
cation bus. No other functional
