•  The arrow direction must match the rotational direction of 
the actuator.  
•  Factory setting:   
•  Alternative switch-on/off for self-adaptation. 
  : ON   
  0: OFF 
•  Factory setting: 0 
 
When turning the self-adaptive feature on, or after a 
software reset with the feature on, the actuator will 
enter a five-minute calibration cycle as the actuator 
adjusts to the rotation limits of the system. 
A software reset happens after power on or may be 
caused by electrostatic discharge (ESD) at levels of 
2kV and above.
