F0003 Undervoltage; F0004 Inverter Overtemperature; F0005 Inverter I2T; F0011 Motor Overtemperature - Siemens MICROMASTER 440 Parameter Manual

Faults and Alarms

F0003 Undervoltage

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

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

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

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
Quit
Refer to F0001
Cause
- wire breakage of the inverter-temperature sensor (heatsink)
Diagnosis & Remedy
- replace the inverter
