ALARM 16, Short circuit
There is short-circuiting in the motor or on the motor terminals.
Turn off the frequency converter and remove the short-circuit.
See section 1.9 for trip levels.
WARNING/ALARM 17, Control word time-out
There is no communication to the frequency converter.
The warning will only be active when par. O-04 Control Word Timeout Function is NOT set to OFF.
If par. O-04 Control Word Timeout Function is set to Stop and Trip, a warning appears and the frequency converter ramps down until it trips, while giving an alarm.
Troubleshooting:
Check connections on the serial communication cable.
Increasepar. O-03 Control Word Timeout Time
Check the operation of the communication equipment.
Verify a proper installation based on EMC requirements. See section 5.
WARNING 22, Hoist mechanical brake
The report value will show what kind it is.
0 = The torque reference was not reached before time-out.
1 = There was no brake feedback before the time-out.
WARNING 23, Internal fan fault
The fan warning function is an extra protective function that checks if the fan is running/mounted. The fan warning can be disabled in par. SP-53 Fan Monitor ([0]
Disabled).
For the 4x, 5x and 6x Frame frequency converters, the regulated voltage to the fans is monitored.
Troubleshooting:
Check fan resistance (see section 6.2.9 or 6.2.10).
Check soft charge fuses (see section 6.2.1 or 6.2.3).
WARNING 24, External fan fault
The fan warning function is an extra protective function that checks if the fan is running/mounted. The fan warning can be disabled in par. SP-53 Fan Monitor ([0]
Disabled).
For the 4x, 5x and 6x Frame frequency converters, the regulated voltage to the fans is monitored.
Troubleshooting:
Check fan resistance (see section 6.2.9 or 6.2.10).
Check soft charge fuses (see section 6.2.1 or 6.2.3).
WARNING 25, Brake resistor short circuit
The brake resistor is monitored during operation. If it short circuits, the brake function is disconnected and the warning appears. The frequency converter still
works, but without the brake function. Turn off the frequency converter and replace the brake resistor (see par. B-15 Brake Check).
WARNING/ALARM 26, Brake resistor power limit
The power transmitted to the brake resistor is calculated: as a percentage, as a mean value over the last 120 seconds, on the basis of the resistance value of the
brake resistor, and the intermediate circuit voltage. The warning is active when the dissipated braking power is higher than 90%. If Trip [2] has been selected in
par. B-13 Braking Thermal Overload, the frequency converter cuts out and issues this alarm, when the dissipated braking power is higher than 100%.
Warning: There is a risk of substantial power being transmitted to the brake resistor if the brake transistor is short-circuited.
WARNING/ALARM 27, Brake chopper fault
The brake transistor is monitored during operation and if it short-circuits, the brake function disconnects and issues a warning. The frequency converter is still
able to run, but since the brake transistor has short-circuited, substantial power is transmitted to the brake resistor, even if it is inactive.
Turn off the frequency converter and remove the brake resistor.
