Motor is running within the programmed current and speed ranges set in par. 4-50
Low and par. 4-53 Warning Speed High . No warnings.
Motor runs at reference speed. No warnings.
An alarm activates the output. No warnings
An alarm or a warning activates the output.
The torque limit set in par. 4-16 Torque Limit Motor Mode or par. 4-17 Torque Limit Generator
Mode has been exceeded.
The motor current is outside the range set in par. 4-18
Motor current is lower than set in par. 4-50
Motor current is higher than set in par. 4-51
Output speed/frequency is outside the frequency range set in par. 4-52
Warning Speed High .
par. 4-53
Output speed is lower than the setting in par. 4-52
Output speed is higher than the setting in par. 4-53
Feedback is outside the range set in par. 4-56
back High .
Feedback is below the limit set in par. 4-56
Feedback is above the limit set in par. 4-57
Thermal warning turns on when the temperature exceeds the limit either in motor, frequency con-
verter, brake resistor, or connected thermistor.
Frequency converter is ready for operation and there is no over-temperature warning.
Frequency converter is ready for operation and is in Auto On mode. There is no over-temperature
warning.
Frequency converter is ready for operation and the mains voltage is within the specified voltage
range (see General Specifications 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 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 Control Word [0] is selected in par. group 8-**.
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.
(FC 302 only) Indicates that the safe stop 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 FC profile
[0] in par par. 8-10 Control Word Profile is selected.
