EoL1 Thermal Relay 1 - The output current causes the motor to be overload. If the output current is 150% higher than the drive’s rated current, the motor can sustain the output for a maximum of 60 seconds.
1. Check the setting for motor full-load current (Pr.05-01).
2. Check if motor is overloaded and change to a higher power motor.
Check drive rectifier & IGBT using multimeter.
Check wiring.
Check drive hardware using multimeter.
