Alarm messages are stored in parameter r2110 under their code number (e.g. 
A0503 = 503) and can be read out from there.  

Possible Causes 

 

Motor power (P0307) does not correspond to the inverter power (P0206) 

 

Motor leads are too long 

 

Earth faults 

Diagnose & Remedy  

Check the following: 

 

Motor power (P0307) must correspond to inverter power (r0206) 

 

Cable length limits must not be exceeded 

 

Motor cable and motor must have no short-circuits or earth faults 

 

Motor parameters must match the motor in use 

 

Value of stator resistance (P0350) must be correct 

 

Motor must not be obstructed or overloaded 

 

Increase the ramp-up-time. 

 

Reduce the boost level (V/f control: P1311 & P1312, Vector control: P1610 & P1611) 

Possible Causes 

 

Overvoltage limit is reached 

 

This warning can occur during ramp down, if the dc-link controller is disabled (P1240 = 0) 

Diagnose & Remedy  

Check the following: 

 

Supply voltage (P0210) must lie within limits indicated on rating plate 

 

DC-link voltage controller must be enabled (P1240) and parameterized properly 

 

Ramp-down time (P1121) must match inertia of load 

 

Required braking power must lie within specified limits 

Possible Causes 

 

Main supply failed 

 

Main supply (P0210) and consequently DC-link voltage (r0026) below specified limit (P2172) 

Diagnose & Remedy  

 

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 

Warning level of inverter heat-sink temperature (P0614) is exceeded, resulting in pulse frequency 
reduction and/or output frequency reduction (depending on parameterization in P0610) 

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 

Possible Causes 

Warning level (P0294) exceeded, output frequency and/or pulse frequency will be reduced if 
parameterized (P0290) 

Diagnose & Remedy  

Check the following:
