Fault
Code
1 Over-current. Current too high in Motor Cable. Check loading.
Check Motor.
Check Cables.
2 Over-voltage. The DC link voltage has exceeded the limits.
- too short a deceleration time Make deceleration time longer.
- high voltage spikes in supply Check input voltage.
3 Earth Fault. Insulation failure in Motor or wiring. Check Motor wires and Motor.
7 Saturation. - component failure Cannot be reset. SWITCH OFF THE POWER and DO
NOT RESTART THE DRIVE. Contact distributor.
9 Undervoltage The DC link voltage is lower than the limits. Check input voltage.
10 Input phase - supply voltage malfuntion Check input voltage.
- a defective fuse or malfunction in the supply cables
13 AC drive undertemperature Heatsink temperature is below -10°C.
14 AC drive overtemperature Heatsink temperature is over 90°C. Check the amount and flow of cooling air.
Overtemperature warning is issued when the heatsink Check the heatsink for dust.
temperature exceeds 85°C. Check the ambient temperature.
Ensure the switching frequency is not too high
in relation to ambient temperature and motor
load
15 Motor stall. Motor stall protection has tripped. Check Motor and load.
16 Motor over-temperature. Motor is overloaded. Decrease motor load.
17 Motor under-load. Motor under-load temperature has tripped. Check load.
32 Fan cooling. - Fan speed does not match the speed reference. Check drive fan. Contact Distributor.
- Fan life time (50,000 h) is reached.
41 IGBT temperature The calculated IGBT temperature is too high. Check loading.
Check ambient temperature and amount of cooling air.
Check parameter settings.
46 Real Time Clock The voltage of the RTC battery is low. Replace the battery.
50 AI low fault Current at the analogue input is less than 4 mA. Check the current loop circuitry.
- control cable is broken or loose.
- signal source has failed.
52 Keypad communication The data connection between the control keypad and the Check keypad connection and possible keypad cable.
fault. frequency converter is broken.
54 Slot fault. Defective option board or slot. Check board and slot.
Contact the nearest Distributor.
