CHAPTER 7 - DIAGNOSTICS AND TROUBLESHOOTING
Note:
(1) In case of E04 Fault due to inverter overtemperature, allow the
inverter to cool down before trying to reset it.
NOTE!
The faults act as follows:
E00 to E06: switches off the relay that has been programmed to
“no fault”, disables the PWM pulses, displays the fault code on the
display. Some data are saved on the EEPROM memory: keypad
reference and EP (electronic potentiometer) (when the function
“backup of the references” at P120 has been enabled), the occurred
fault number, the status of the integrator of the I x t function
(overcurrent).
E24: Indicates the fault code on the LED display.
E08, E09, E31 and E41: do not allow inverter operation (it is not
possible to enable the inverter); the fault code is indicated on the
LED display.
FAULT RESET
(1)
POSSIBLE CAUSES
E04 Power-on Ambient temperature too high (> 50 ºC), (> 40 °C for the
Inverter Manual (key ) 15.2 Amodel) and/or output current too high.
Overtemperature Auto-reset Blocked or defective fan.
DI NOTE
The heat sink overtemperature protection(E04) is activated
when the heat sink temperature (P008) reaches 103 ºC
or 133 ºC for the 15.2 A model.
E05 P156 set too low for the motor that is being used.
Overload Motor is under an actual overload condition.
at output
I x t Function
E06 Wiring at DI1 to DI4 inputs is open [not connected to
External Error GND (pin 5 of the XC1 control connector)].
