Electronic thermal relay 1 protection (EoL1)

Electronic thermal relay 1 protection. The drive coasts to stop once it activates.

Start counting when output current > 105% of motor 1 rated current

Action time - Pr.06-14 (if the output current is larger than 105% of motor 1 rated current again within 60 sec., the counting time reduces and is less than Pr.06-14)

The load is too large - Reduce the load.

Decrease low-speed operation time.
Replace the drive with a dedicated to VFD model.

Increase the motor capacity

Check drive rectifier & IGBT using multimeter.
Check wiring.
Check drive hardware using multimeter.
