Error 
code 
Diagnostic code  Meaning for the LMV36... system  Remedy 
1. Basic unit is not standardized for this motor  repeat standardization. 
 
Caution! 
Settings of fuel-air ratio control must be checked! 
2. Ramp time settings of the VSD are not shorter than those of the basic unit (parameters 522,  
    523) or the setting for the modulating operating ramp is incorrect (parameter 544) 
3. Characteristic of the VSD is not linear. Configuration of the voltage input at the VSD must  
    accord with that of the basic unit (parameter 645). 
4. VSD does not follow quickly enough the changes of the basic unit. Check settings of the VSD 
    (input filter, slippage compensation, hiding different speeds)
 
1  Control range limitation at the bottom VSD speed was too high 
  2  Control range limitation at the top  VSD speed was too low 
81 
1  Interrupt limitation speed input 
Too much electromagnetic interference on the sensor line 
 improve EMC 
82  #  Error during VSD’s speed standardization 
 
 
1  Timeout of standardization (VSD ramp down time too long) 
Timeout at the end of standardization during ramp down of the VSD 
 Ramp time settings of the VSD are not shorter than those of the basic unit (parameter: 523) 
 
2  Storage of standardized speed not successful 
Error during storage of the standardized speed 
 lock the basic unit, then reset it and repeat the standardization 
 
3  Line interruption speed sensor 
Basic unit receives no pulses from the speed sensor: 
1. Motor does not turn. 
2. Speed sensor is not connected. 
3. Speed sensor is not activated by the sensor disk (check distance) 
 
4 
Speed variation / VSD ramp up time too long / speed below 
minimum limit for standardization 
Motor has not reached a stable speed after ramp up. 
1. Ramp time settings of the VSD are not shorter than those of the basic unit (parameters 522, 
    523). 
2. Characteristic of the VSD is not linear. Configuration of the voltage input at the VSD must  
    accord with that of the basic unit (parameter 645). 
3. VSD does not follow quickly enough the changes of the basic unit. Check settings of the VSD 
    (input filter, slippage compensation, hiding different speeds) 
4. Speed of VSD lies below the minimum for standardization (650 1/min) 
 
5  Wrong direction of rotation 
Motor’s direction of rotation is wrong. 
1. Motor turns indeed in the wrong direction 
 
 change parameterization of the direction of rotation or interchange 2 live conductors. 
2. Sensor disk is fitted the wrong way 
 
 turn the sensor disk. 
 
6 Unplausible sensor signals 
The required pulse pattern (60°, 120°, 180°) has not been correctly identified. 
1. Speed sensor does not detect all tappets of the sensor disk
