Cause : Measured inertia has exceeded the parameter range (RFC-A mode only) comes when the drive has tripped during a rotating autotune or mechanical load measurement test. The cause of the trip can be identified from the associated sub-trip number.

Sub-trip & Reason
1 - Measured inertia has exceeded the parameter range during a mechanical load measurement
3 - The mechanical load test has been unable to identify the motor inertia

• Check motor cable wiring is correct.
