F0003 Undervoltage

STOP

II

Quit

Refer to F0001

Cause

-

line voltage failed

-

shock stressing outside the permissible limits.

Diagnosis & Remedy

Please check the following:
-

is the line supply voltage within the permissible range?

-

is the line supply voltage stable with respect to sporadic failures and voltage dips (brown-outs) ?

F0004 Inverter overtemperature

STOP II

Quit

Refer to F0001

Cause

- inadequate

cooling

-

ambient temperature is too high.

ambient temperature is too high.

Diagnosis & Remedy

Please check the following:
-

is the pulse frequency P1800 set to the factory setting ? If required reset P1800.

-

does the ambient temperature lie within the permissible limits ?

-

reduce the load and / or ensure adequate cooling

Please check the following:
-

does the fan rotate if the inverter is operational ?

F0005 Inverter I2T

STOP II

Quit

Refer to F0001

Cause

- inverter

overloaded.

-

load duty cycle too high.

-

the motor power rating (P0307) is greater than that of the inverter (r0206).

-

100 % overload reached (refer to utilization r0036)

Diagnosis & Remedy

Please check the following:
-

does the load duty cycle lie within the permissible limits?

-

use a motor with a lower rating (motor power P0307 is greater than ls inverter power r0206)

F0011 Motor overtemperature

STOP II

Quit

Refer to F0001

Cause

Motor overloaded

Diagnosis & Remedy

Please check the following:
-

is the load cycle correct ?

-

are the rated/nominal motor overtemperatures correct (P0626-P0628) ?

-

is the alarm threshold correct for the motor temperature (P0604) ?

F0012 No inverter temperature signal

STOP I

Quit

Refer to F0001

Cause

-

wire breakage of the inverter-temperature sensor (heatsink)

Diagnosis & Remedy

-

replace the inverter
