Check for short circuits or ground faults in the main circuit cables. Evaluate Motor/Drive Capacity
Resolving the warning requires evaluating five primary problem areas spanning electrical wiring, mechanical resistance, and software configurations. 1. Wiring Inefficiencies and Faulty Contacts

Unlike a hard fault that stops the motor immediately, A.910 acts as a precursor. If the underlying cause is not addressed, the drive will eventually trigger a protective shutdown to prevent hardware damage. Description Warning (Pre-alarm) Primary Meaning Overload (Approaching thermal limit) Associated Alarms A.710 (Instantaneous Overload), A.720 (Continuous Overload) Common Causes
Common sub-codes:
If the temperature inside the electrical control cabinet exceeds 55°C, the amplifier’s heat dissipation performance drops sharply, lowering the threshold for thermal strain.
The most common cause is damaged, improperly shielded, or incorrectly connected encoder cabling. Check for short circuits or ground faults in
If using V/f Control (no auto-tuning):
