LAMBDA SC OPERATION MANUAL – REV. 1.14C (20190606) 

control electronics, the resulting move may differ from that commanded by the control 

electronics. For instance, if enough external force is applied, the motor shaft may be rotated 
even though the command signal has not changed. For small rotations (less than 3.6 

degrees), the motor shaft will return to the correct position if the force is removed. For larger 
rotations, the shaft will stop at the nearest of the 50 correct positions for that command 
signal when the external force is removed.
