Operation Example
No Position Command Input (Servo ON)
No position command is entered. The Servomotor's allowable operating range is the range set
in object 3514 hex on both the right and left. An overrun limit error will occur (Error No. 34.0) if
the load enters the error range, or the shaded area in the drawing below, due to vibration.
Right Side Operation (Servo ON)
When a rightward position command is entered, the Servomotor's allowable operating range
increases for the commanded amount. The range will be the result where the rotation set for
3514 hex is added on both sides for the position command.
Left Side Operation (Servo ON)
When a leftward position command is entered, the Servomotor's allowable operating range
further increases.
