[8] Run on reference / no warning Motor runs at reference speed.
[9] Alarm An alarm activates the output. There are no warnings.
[10] Alarm or warning An alarm or a warning activates the output.
[11] At torque limit The torque limit set in par. F-40 Torque Limiter (Driving) or par. 4-17F-41 has been exceeded.
[12] Out of current range The motor current is outside the range set in par. F-43 Current Limit.
[13] Below current, low Motor current is lower than set in par. H-70 Warning Current Low.
[14] Above current, high Motor current is higher than set in par. H-71 Warning Current High.
[15] Out of range Output frequency is outside the frequency range set in par. H-70 Warning Current Low and par.
H-71 Warning Current High.
[16] Below speed, low Output speed is lower than the setting in par. H-72 Warning Speed Low.
[17] Above speed, high Output speed is higher than the setting in par. H-73 Warning Speed High.
[18] Out of feedback range Feedback is outside the range set in par. H-76 Warning Feedback Low and par. H-77 Warning Feedback
High.
[19] Below feedback low Feedback is below the limit set in par. H-76 Warning Feedback Low.
[20] Above feedback high Feedback is above the limit set in par. H-77 Warning Feedback High.
[21] Thermal warning The thermal warning turns on when the temperature exceeds the limit in the motor, the frequency con-
verter, the brake resistor, or the thermistor.
[22] Ready, no thermal warning Frequency converter is ready for operation and there is no over-temperature warning.
[23] Remote, ready, no thermal warning Frequency converter is ready for operation and is in Auto mode. There is no over-temperature warning.
[24] Ready, no over-/ under voltage Frequency converter is ready for operation and the mains voltage is within the specified voltage range
(see General Specifications section).
[25] Reverse Reversing. 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 and stop Use in performing a coasting stop and in torque limit condition. If the frequency converter has received
a stop signal and is at the torque limit, the signal is Logic ‘0’.
[28] Brake, no brake warning 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 modules. Use the output/relay to cut out the main voltage from
the frequency converter.
[31] Relay 123 Relay is activated when Control Word [0] is selected in parameter group O-##.
[32] Mechanical brake control Enables control of an external mechanical brake, see description in the section Control of Mechanical
Brake, and par. group B-2#.
[40] Out of ref range
[41] Below reference low
[42] Above reference high
[45] Bus Ctrl Controls output via bus. The state of the output is set in par. E-90 Digital & Relay Bus Control. The output
state is retained in the event of bus time-out.
[46] Bus Ctrl On at timeout Controls output via bus. The state of the output is set in par. E-90 Digital & Relay Bus Control. In the event
of bus time-out the output state is set high (On).
[47] Bus Ctrl Off at timeout Controls output via bus. The state of the output is set in par. E-90 Digital & Relay Bus Control. In the event
of bus time-out the output state is set low (Off).
[55] Pulse output
[60] Comparator 0 See par. group LC-1#. If Comparator 0 is TRUE, the output will go high. Otherwise, it will be low.
[61] Comparator 1 See par. group LC-1#. If Comparator 1 is TRUE, the output will go high. Otherwise, it will be low.
