Error messages
Remedy
•
Find reason for short circuit; check motor cables
•
Check brake resistor
Use shorter/low-capacity motor cables
Check motor, check motor cable
Use shorter/low-capacity motor cables
Earth fault detection can be deactivated for checking
•
Increase acceleration time
•
Check drive selection
Check wiring
Check motor
•
Allow longer deceleration time
•
Check the external brake resistor selection
Check drive selection
•
Check drive selection
•
Check setting under C0120
•
Allow controller to cool down and ensure better
ventilation
•
Check ambient temperature
Clean heat sink
•
Check drive selection
•
Check load, if necessary replace sluggish, defective
bearings
Check drive selection
Connect PTC or switch-off monitoring (C0585=3)
•
Reduce controller load
•
Improve cooling
•
Check fan in the controller
Check drive selection
Connect PTC or switch-off monitoring (C0585=3)
Check voltage supply
•
Prolong deceleration times.
•
For operation with external brake resistor:
– Check dimensioning, supply and connection of
brake resistor
– Increase the deceleration times
Check motor cable and motor for earth fault (disconnect
motor from inverter)
It is absolutely necessary to repeat the data transfer or
load the factory setting before the controller is enabled.
