Option: Function:
[12] Out of current The motor current is outside the
range range set in parameter 4-18 Current
Limit.
[13] Below current, low Motor current is lower than set in
parameter 4-50 Warning Current Low.
[14] Above current, Motor current is higher than set in
high parameter 4-51 Warning Current High.
[15] Out of speed Output speed/frequency is outside the
range frequency range set in
parameter 4-52 Warning Speed Low
and parameter 4-53 Warning Speed
High.
[16] Below speed, low Output speed is lower than the
setting in parameter 4-52 Warning
Speed Low
[17] Above speed, high Output speed is higher than the
setting in parameter 4-53 Warning
Speed High.
[18] Out of feedb. Feedback is outside the range set in
range parameter 4-56 Warning Feedback Low
and parameter 4-57 Warning Feedback
High.
[19] Below feedback, Feedback is below the limit set in
low parameter 4-56 Warning Feedback Low.
[20] Above feedback, Feedback is above the limit set in
high parameter 4-57 Warning Feedback High.
[21] Thermal warning Thermal warning turns on when the
temperature exceeds the limit either
in motor, frequency converter, brake
resistor, or connected thermistor.
[22] Ready,no thermal Frequency converter is ready for
W operation and there is no over-
temperature warning.
[23] Remote,ready,no Frequency converter is ready for
TW operation and is in Auto On mode.
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 The motor runs (or is ready to run)
clockwise when logic=0 and counter
clockwise when logic=1. The output

Function:
changes as soon as the reversing
signal is applied.
Active communication (no time-out)
via the serial communication port.
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'.
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
[0] Control Word is selected in
parameter group 8-** Comm. 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. Usually, solved by
connecting an external relay to the
selected digital output.
(FC 302 only) Indicates that the Safe
Torque Off on terminal 37 has been
activated.
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 [0] FC profile in
parameter 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:
