E.Whether the FIN heatsink is overheated, whether the surrounding temperature is too high, and whether the cooling heatsink is blocked.

E.GF output side ground fault overcurrent protection motor.

Whether the connecting wire is grounded, whether the E.OHT external thermal relay action motor is overheated.

In any of Pr.180-Pr.186 (input terminal function selection), whether the setpoint 7 (OH signal) is set correctly.

E.BE the abnormal reduction of load J by braking transistors, whether the frequency of braking is appropriateE.OLT stall prevents the motor from using E.OPT option in an overload state, and alarms E.OP1-OP3 option socket abnormal function setting, operation error.

(1-3 display option insert slogan) E.PE whether the memory factor of the parameter is abnormal, and the number of parameter writing returns is too much

E. Confirm whether the device where PUEPU or PU is too loose when PUEPU is prolapsed

The set value of Pr.75 E.RET retry overflow investigates the cause of the anomaly
