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) 

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 

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) 

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) 

Possible Causes 

Wire breakage of inverter temperature (heatsink) sensor 

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
