Function:
Motor current is higher than set in
4-51 Warning Current High.
Output speed/frequency is outside
the frequency ranges set in
4-52 Warning Speed Low and
4-53 Warning Speed High.
Output speed is lower than the
setting in 4-52 Warning Speed Low
Output speed is higher than the
setting in 4-53 Warning Speed High.
Feedback is outside the range set in
4-56 Warning Feedback Low and
4-57 Warning Feedback High.
4-56 Warning Feedback Low.
Feedback is above the limit set in
4-57 Warning Feedback High.
Thermal warning turns on when the
temperature exceeds the limit either
in motor, Adjustable frequency drive,
brake resistor, or connected
thermistor.
for operation and there is no
overtemperature warning.
for operation and is in auto on
mode. There is no overtemperature
warning.
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).
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.
Active communication (no timeout)
via the serial communication port.

Function:
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'.
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 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.
Digital output/relay is activated
when Control Word [0] is selected in
parameter group 8-**.
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.
(FC 302 only) Indicates that the safe
stop on terminal 37 has been
activated.
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.
Activate relay 2 FC 302 only) by
control word from serial communi-
cation bus. No other functional
