Siemens Micromaster 440 Operating Instructions Manual page 93

Issue 12/02
F0003 UnderVoltage
Possible Causes
! Main supply failed
! Shock load outside specified limits
Diagnose & Remedy
Check the following:
1. Supply voltage (P0210) must lie within limits indicated on rating plate
2. Supply must not be susceptible to temporary failures or voltage reductions
! Enable kinetic buffering (P1240 = 2)
F0004 Inverter Over Temperature
Possible Causes
! Ventilation inadequate
! Ambient temperature is too high
Diagnose & Remedy
Check the following:
1. Load conditions and duty cycle must be appropriate
2. Fan must turn when inverter is running
3. Pulse frequency (P1800) must be set to default value
4. Ambient temperature could be higher than specified for the inverter
Additional meaning for MM440 Frame size FX & GX:
Fault value = 1: Rectifier overtemperature
2
F0005 Inverter I t
Possible Causes
! Inverter overloaded
! Duty cycle too demanding
! Motor power (P0307) exceeds inverter power capability (r0206)
Diagnose & Remedy
Check the following:
1. Load duty cycle must lie within specified limits
2. Motor power (P0307) must match inverter power (r0206)
F0011 Motor Over Temperature
Possible Causes
Motor overloaded
Diagnose & Remedy
Check the following:
1. Load duty cycle must be correct
2. Motor nominal overtemperatures (P0626-P0628) must be correct
3. Motor temperature warning level (P0604) must match
If P0601 = 0 or 1, check the following:
1. Check if name plate data are correct (if not perform quick commissioning)
2. Accurate equivalent circuit data can be found by performing motor identification (P1910=1)
3. Check if motor weight (P0344) is reasonable. Change if necessary
4. Via P0626, P0627, P0628 the standard overtemperatures can be changed, if the motor is not a
Siemens standard motor
If P0601 = 2, check the following:
1. Check if temperature shown in r0035 is reasonable
2. Check if the sensor is a KTY84 (other sensors are not supported)
