Category: Alarm

Cause

Condition: The servo drive estimates inertia abnormally during automatic tuning. Causes:

1. Acceleration/deceleration time is too long.
2. Rotation speed is too low.
3. Mechanical load inertia is too large.
4. Mechanical inertia changes too abruptly.

Corrective action

1. Acceleration/deceleration time between 0 rpm and 3,000 rpm must be no more than 1.5 seconds.
2. Minimum speed must be at least 200 rpm; at least 500 rpm is recommended.
3. Load inertia must be no more than 50 times motor inertia.
4. Not suitable for applications with excessively abrupt inertia ratio changes. Reset the alarm.
