Setting to Enable/Disable Overtravel

Use PnBA4 (Input Signal Settings) to enable/disable the overtravel function.
You do not need to wire the overtravel input signals if you are not going to use the overtravel
function.

*1.
If overtravel occurs, the servo will be turned OFF regardless of the rotation direction.
*2.
The motor will stop if overtravel occurs, but you can input a reference to drive the motor in the opposite direc-
tion.
Refer to the following section for information on stopping methods other than those for over-
travel.
