Note:
(1) In case of E04 Fault due to inverter overtemperature,
allow the inverter to cool down before trying to reset it.
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 IxT function
(overcurrent).
E24: Indicates the fault code on the LED display.
E08, E09, E31 e E41: do not allow inverter operation (it is
not possible to enable the inverter); the fault code is
indicated on the LED display.
POSSIBLE CAUSES
Ambient temperature too high (>50ºC) and/or output current
too high.
NOTE
The heat sink overtemperature protection (E04) is activated
when the heat sink temperature (P008) reaches 103ºC.
P156 set too low for the motor that is being used.
Motor is under an actual overload condition.
Wiring at DI1 to DI4 inputs is open (not connected to
GND (pin 5 of the XC1 control connector)].
Electrical noise.
Memory with corrupted values.
Incompatible parameters were programmed
Refer to table 5.1.
Inverter control circuit is defective.
Electrical noise in the installation (electromagnetic
interference).
Inverter power circuit is defective.
