(Reverse overtravel)
Connect limit switches as shown below to prevent

For example, reverse rotation is possible during
forward overtravel.

■Important
When using overtravel to stop the servomotor during position control, the position error pulses are
present. A clear signal(CLR)input is required to clear the error pulses.

C A U TIO N
When using the servomotor on a vertical axis, the workpiece may fall in the overtravel condition.
To prevent this, always set the zero clamp after stopping with Pn004.0=5.
