6 Troubleshooting Issue 03/01
MICROMASTER 411 & COMBIMASTER 411 Operating Instructions
82 6SE6400-5CA00-0BP0
Shock load outside specified limits
Diagnose & Remedy
Check the following:
Supply voltage (P0210) must lie within limits indicated on rating plate
Supply must not be susceptible to temporary failures or voltage reductions
Enable kinetic buffering (P1240 = 2)
F0004 Inverter Over Temperature OFF2
Possible Causes
Ventilation inadequate
Ambient temperature is too high
Diagnose & Remedy
Check the following:
Load conditions and duty cycle must be appropriate
Fan must turn when inverter is running
Pulse frequency (P1800) must be set to default value
Ambient temperature could be higher than specified for the inverter
Additional meaning for MM440 Frame size FX & GX:
Fault value = 1: Rectifier overtemperature
= 2: Ambient overtemperature
= 3: EBOX overtemperature
F0005 Inverter I 2 t OFF2
Possible Causes
Inverter overloaded
Duty cycle too demanding
Motor power (P0307) exceeds inverter power capability (r0206)
Diagnose & Remedy
Check the following:
Load duty cycle must lie within specified limits
Motor power (P0307) must match inverter power (r0206)
F0011 Motor Over Temperature OFF1
Possible Causes
Motor overloaded
Diagnose & Remedy
Check the following:
Load duty cycle must be correct
Motor nominal overtemperatures (P0626-P0628) must be correct
Motor temperature warning level (P0604) must match
If P0601 = 0 or 1, check the following:
Check if name plate data are correct (if not perform quick commissioning)
Accurate equivalent circuit data can be found by performing motor identification (P1910=1)
Check if motor weight (P0344) is reasonable. Change if necessary
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:
Check if temperature shown in r0035 is reasonable
Check if the sensor is a KTY84 (other sensors are not supported)
F0012 Inverter temp. signal lost OFF2
Possible Causes
Wire breakage of inverter temperature (heatsink) sensor
F0015 Motor temperature signal lost OFF2
Possible Causes
Open or short circuit of motor temperature sensor. If signal loss is detected, temperature monitoring
switches over to monitoring with the motor thermal model
