Troubleshooting

6 Troubleshooting

VLT® Micro Drive FC 51 Programming Guide

A warning or an alarm is signalled by the relevant LED on

front of the frequency converter and indicated by a

the code on the display.

A warning remains active until its cause is no longer present. Under certain circumstances operation of the motor may still be continued. Warning messages may be critical, but are not necessarily so.

In the event of an alarm, the frequency converter will have tripped. Alarms must be reset to restart operation once their cause has been rectified.

This may be done in four ways:

1. By pressing [Reset].

2. Via a digital input with the “Reset” function.

3. Via serial communication.

NOTE

After

a manual reset press [Reset], [Auto On] or [Hand On]

to restart the motor.

If an alarm cannot be reset, the reason may be that its

has not been rectified, or the alarm is trip-locked

cause (see also Table 6.1).

CAUTION

Alarms that are trip-locked offer additional protection, means

that the mains supply must be switched off before the alarm can be reset. After being switched back on, the frequency converter is no longer blocked and may be reset as described above once the cause has been rectified. Alarms that are not trip-locked can also be reset using the automatic reset function in 14-20 Reset Mode (Warning: automatic wake-up is possible!) If a warning and alarm is marked against a code in the Table 6.1, this means that either a warning occurs before an alarm, or it can be specified whether it is a warning or an alarm that is to be displayed for a given fault. This is possible, for instance, in 1-90 Motor Thermal Protection. After an alarm or trip, the motor carries on coasting, and the alarm and warning flash on the frequency converter. Once the problem has been rectified, only the alarm continues flashing.

(X) Dependent on parameter

trip is the action when an alarm has appeared. The trip

A will coast the motor and can be reset by pressing [Reset] or make a reset by a digital input (parameter group 5-1* [1]). The original event that caused an alarm cannot damage the frequency converter or cause dangerous conditions. A trip lock is an action when an alarm occurs, which may cause damage to frequency converter or connected parts. A trip lock situation can only be reset by a power cycling.

VLT® Micro Drive FC 51 Programming Guide

WARNING/ALARM 8, DC under voltage

the intermediate circuit voltage (DC link) drops below

If the under voltage limit, the frequency converter checks if a 24 V DC backup supply is connected. If no 24 V DC backup supply is connected, the frequency converter trips after a fixed time delay. The time delay varies with unit size.

Troubleshooting

Check that the supply voltage matches the frequency converter voltage.

Perform input voltage test. Perform soft charge circuit test.

WARNING/ALARM 9, Inverter overload The frequency converter is about to cut out because of an

overload (too high current for too long). The counter for electronic, thermal inverter protection issues a warning at 98% and trips at 100%, while giving an alarm. The frequency converter cannot be reset until the counter is below 90%. The fault is that the frequency converter has run with more than 100% overload for too long.

Troubleshooting

Compare the output current shown on the LCP with the frequency converter rated current.

Compare the output current shown on the LCP with measured motor current.

Display the Thermal Drive Load on the LCP and monitor the value. When running above the frequency converter continuous current rating, the counter increases. When running below the frequency converter continuous current rating, the counter decreases.

WARNING/ALARM 10, Motor overload temperature According to the electronic thermal protection (ETR), the motor is too hot. Select whether the frequency converter gives a warning or an alarm when the counter reaches 100% in 1-90 Motor Thermal Protection. The fault occurs when the motor is overloaded by more than 100% for too long.

Troubleshooting

Check for motor overheating. Check if the motor is mechanically overloaded Check that the motor current set in 1-24 Motor

Current is correct. Ensure that Motor data in parameters 1-20

through 1-25 are set correctly. Running AMT in 1-29 Automatic Motor Tuning

(AMT). The inverter peak current limit (approx. 200% of the rated current) is exceeded. The warning will last approx. 8-12 s, then the frequency converter trips and issues an alarm. Turn off the frequency converter and check if the motor shaft can be turned and if the motor size

WARNING/ALARM 11, Motor thermistor over temp The thermistor might be disconnected. Select whether the frequency converter gives a warning or an alarm in 1-90 Motor Thermal Protection.

Troubleshooting

WARNING/ALARM 13, Over current The inverter peak current limit (approx. 200% of the rated current) is exceeded. The warning will last approx. 8-12 s, then the frequency converter trips and issues an alarm. Turn off the frequency converter and check if the motor shaft can be turned and if the motor size matches the frequency converter. If extended mechanical brake control is selected, trip can be reset externally.

Troubleshooting:

ALARM 14, Earth (ground) fault There is current from the output phases to earth, either in the cable between the frequency converter and the motor or in the motor itself.

Troubleshooting:

ALARM 16, Short circuit There is short-circuiting in the motor or motor wiring.

Remove power to the frequency converter and repair the short circuit.

WARNING/ALARM 17, Control word timeout There is no communication to the frequency converter. The warning is only active when 8-04 Control Word Timeout Function is NOT set to OFF. If 8-04 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. 8-03 Control Timeout Time could possibly be increased.

Check for motor overheating. Check if the motor is mechanically overloaded.

Remove power and check if the motor shaft can be turned.

Check that the motor size matches the frequency converter.

Check parameters 1-20 through 1-25. for correct motor data.

Remove power to the frequency converter and repair the earth fault.

Check for earth faults in the motor by measuring the resistance to ground of the motor leads and the motor with a megohmmeter.

WARNING 25, Brake resistor short circuit The brake resistor is monitored during operation. If a short circuit occurs, the brake function is disabled and the warning appears. The frequency converter is still operational but without the brake function. Remove power to the frequency converter and replace the brake resistor (see 2-15 Brake Check).

WARNING/ALARM 27, Brake chopper fault The brake transistor is monitored during operation and if a short circuit occurs, the brake function is disabled and a warning is issued. The frequency converter is still operational but, since the brake transistor has shortcircuited, substantial power is transmitted to the brake resistor, even if it is inactive. Remove power to the frequency converter and remove the brake resistor.

WARNING/ALARM 28, Brake check failed The brake resistor is not connected or not working.

ALARM 29, Heatsink temp The maximum temperature of the heatsink has been exceeded. The temperature fault will not reset until the temperature falls below a defined heatsink temperature. The trip and reset points are different based on the frequency converter power size.

Troubleshooting

Check for the following conditions.

Ambient temperature too high. Motor cable too long. Incorrect airflow clearance above and below the

frequency converter. Blocked airflow around the frequency converter. Damaged heatsink fan. Dirty heatsink.

ALARM 30, Motor phase U missing Motor phase U between the frequency converter and the motor is missing.

Remove power from the frequency converter and check motor phase U.

ALARM 31, Motor phase V missing Motor phase V between the frequency converter and the motor is missing.

Remove power from the frequency converter and check motor phase V.

ALARM 32, Motor phase W missing Motor phase W between the frequency converter and the motor is missing.

Remove power from the frequency converter and check motor phase W.
