EoL1 on DELTA inverters: Motor 1 electronic thermal overload

DELTA inverters: MS300

Disconnect the supply and wait for the capacitors to discharge before opening the inverter or touching its terminals.

Common causes

1. 1Motor current above the setting
2. 2Wrong motor rated current in the parameters
3. 3Long low-speed running of a self-cooled motor

Try first

1. 1Set the motor rated current from the nameplate (Pr.05-01)
2. 2Check the mechanical load and bearings
3. 3Review the motor thermal protection setting (Pr.06-13)
