CHAPTER 6 - DIAGNOSTICS AND TROUBLESHOOTING
E02 Power-on Power supply voltage too low, causing a DC link
DC link Manual (key ) voltage lower than the minimum allowed value (read the
undervoltage Auto-reset value in parameter P004)
DI Ud < 200 V - 200 - 240 V models
Ud < 360 V - 380 - 480 V models
E04 Ambient temperature too high (> 40
o
C [104 ºF]) and/or
Overtemperature output current too high
at the power Blower locked or defective
heatsink or in the
inverter internal air
E05 P156 set too low for the motor that is being used
Motor/inverter Too much load on motor shaft
overload
Ixt function
E06 Any DI programmed for external fault
External fault detection is open (not connected to GND - XC1)
E08 Electrical noise
CPU error
(Watchdog)
E09 Contact Eliwell Memory with corrupted values
Program memory
error (Checksum)
E10 Power-on Defective contact in the HMI-CFW08-RS cable
Keypad copy Manual (key ) Electrical noise in the installation (electromagnetic
function error Auto-reset interference)
DI
E14 Power-on Motor is not connected to the inverter output
Self-tuning Manual (key ) Wrong motor connection (wrong voltage, lack of one
routine error Self-tuning routine error phase)
The used motor is too small for the inverter
(P401 < 0.3 x P295). Use V/Fcontrol
The value of P409 (stator resistance) is too high for the
used inverter
