8105

Category: Alarm

Cause

Condition: an error occurred during regeneration. Causes:

1. Incorrect regenerative resistor selection or no external regenerative resistor connected; during regeneration, the regenerative voltage remains at 400V for a period of time.
2. No regenerative resistor is used, but the user has not set regenerative resistor capacity (P1.053) to zero.

Corrective action

1. Verify the regenerative resistor connection, recalculate its resistance, and correctly reset P1.052 and P1.053. If the alarm persists, return the drive to the original manufacturer.
2. If no regenerative resistor is used, set regenerative resistor capacity (P1.053) to zero. Reset the alarm.
