E003

3.0

Inverter overcurrent

I

2

t limit has triggered, e.g. > 1.5 x I

n

for 60s (please also note

P504)

 Continuous overload at inverter output

3.1

Overcurrent chopper

I

2

t limit for braking resistance has triggered (please note P555,

P556, P557)

 Avoid overcurrent in braking resistance

 Switch on flying start P250 for fan drives

3.2

Inverter overcurrent

Derating at f < 2 Hz

E004

4.0

Overcurrent module

Error signal from module (short duration)

 Short-circuit or earthing at inverter output

 Use external output choke (motor cable is too long)

4.1

Overcurrent pulse switch-off

Pulse switch-off P537 has triggered

 FI is overloaded

 Check motor data

E005

5.0

Overvoltage DC link

Inverter link voltage is too high

 Reduce energy return by means of a braking resistance

 Extend braking time (P103)

 If necessary, set switch-off mode (P108) with delay (not for

lifting equipment)

 Extend emergency stop time (P426)

5.1

Overvoltage mains

Mains voltage is too high

 Please check (380V-20% to 480V+10%)

E006

6.0

DC link circuit undervoltage
(charging error) )

Inverter mains / link voltage too low

 Check mains voltage (380V-20% to 480V+10%)

6.1

Mains undervoltage

E007

7.0

Mains phase failure

One of the three mains input phases was or is interrupted.

 Check mains phases (380V -20% to 480V +10%), possibly too

low?

 All three mains phases must be symmetrical.

OFF

Note:

OFF appears in the display when the three mains phases are uniformly reduced, i.e. when
a normal mains switch off occurs during operation.

E008

8.0

EEPROM parameter loss

Error in EEPROM data, EMC interference (see also E020)

Software version of the stored data set not compatible with the
software version of the FI.

Note: Faulty parameters are automatically reloaded (default

data).

8.1

Invalid inverter type

 EEPROM faulty

8.2

External EEPROM copy error
(ControlBox)

 Check ControlBox for correct position.

 ControlBox EEPROM faulty (P550 = 1).
