Cause : IN CHOKE TEMP comes when the temperature of the input choke (an inductor used to filter harmonics and improve power quality) has exceeded its acceptable operating range.

This can be caused by several factors, including high ambient temperatures, inadequate cooling, overloading, or a malfunctioning choke.

1. Stop drive. Let it cool down.
2. Check ambient temperature.
3. Check that fan rotates in correct direction and air flows freely.
