Option: Function:
[14] Above current, high Motor current is higher than set in
par. 4-51 Warning Current High.
[15] Out of speed range Output speed/frequency is outside the
frequency range set in
par. 4-52 Warning Speed Low and
par. 4-53 Warning Speed High.
[16] Below speed, low Output speed is lower than the setting
in par. 4-52 Warning Speed Low
[17] Above speed, high Output speed is higher than the
setting in par. 4-53 Warning Speed
High.
[18] Out of feedb. range Feedback is outside the range set in
par. 4-56 Warning Feedback Low and
par. 4-57 Warning Feedback High.
[19] Below feedback, Feedback is below the limit set in
low par. 4-56 Warning Feedback Low.
[20] Above feedback, Feedback is above the limit set in
high par. 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 W Frequency converter is ready for
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 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'.

Function:
Brake, no brake war Brake is active and there are no
warnings.
Brake ready, no Brake is ready for operation and there
fault are no faults.
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.
Relay 123 Digital output/relay is activated when
Control Word [0] is selected in par.
group 8-**.
Mech brake ctrl Selection of mechanical brake control.
When selected parameters in par.
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.
Safe stop active (FC 302 only) Indicates that the safe
stop on terminal 37 has been activa-
ted.
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 par
par. 8-10 Control Word Profile is
selected.
Control word bit 12 Activate relay 2 FC 302 only) by control
word from fieldbus. No other function-
al impact in the frequency converter.
Typical application: controlling auxili-
ary device from fieldbus. The function
is valid when FC profile [0] in
par. 8-10 Control Word Profile is
selected.
Motor feedback Failure in the speed feedback loop
error from motor running in closed loop.
The output can eventually be used to
prepare switching the drive in open
loop in emergency case.
Tracking error When the difference between calcula-
ted speed and actual speed in
