28 Error code list (of all LMV2 / LMV3 types)
Recommended measures or causes
1. Check the setting of the actuator type (parameter 613.1)
2. Check to see if actuators have been mixed up
3. Check to see if actuator is locked or overloaded
Parameterization of an actuator (e.g. the reference position) has been changed.
To trigger new referencing, this error will be set
Target position could not be reached within the required tolerance band.
 Check to see if the actuator is locked or overloaded.
Line interruption detected at actuator's terminals.
 Check wiring (voltage X54 across pin 5 or 6 and pin 2 >0.5 V).
Check position differential between the curvepoints and the modulating operating ramp setting
(parameter 544).
1. Modulating operating ramp 32 seconds
The slope of the curve may be a maximum position change of 31° (15° for SQM33.6 and 9° for
SQM33.7) between 2 curve points in modulating mode.
2. Modulating operating ramp 64 seconds
The slope of the curve may be a maximum position change of 62° (30° for SQM33.6 and 18° for
SQM33.7) between 2 curve points in modulating mode.
Actuator was overloaded or mechanically twisted.
1. Check the setting of the actuator type (parameter 613.0 or 614)
2. Check to see if the actuator is blocked somewhere along its working range.
3. Check to see if the torque is sufficient for the application.
Target position could not be reached within the required tolerance band.
 Check to see if the actuator is locked or overloaded.
Line interruption detected at actuator's terminals.
 Check wiring (voltage X53 across pin 5 or 6 and pin 2 >0.5 V).
Check position differential between the curvepoints and the modulating operating ramp setting
(parameter 544).
