Setting To Enable/Disable Overtravel; Motor Stopping Method For Overtravel - YASKAWA SGD7S-****20A Series Product Manual

5.11.2

Setting to Enable/Disable Overtravel

You can use Pn50A = n.X (P-OT (Forward Drive Prohibit) Signal Allocation) and Pn50B =
n.X (N-OT (Reverse Drive Prohibit) Signal Allocation) to enable and disable the overtravel
function.
You do not need to wire the overtravel input signals if you are not going to use the overtravel
function.

You cannot decelerate a Servomotor to a stop during torque control. For torque control, the Servomotor will be
stopped with the dynamic braking or coast to a stop (according to the setting of Pn001 = n.X (Motor Stop-
ping Method for Servo OFF and Group 1 Alarms)), and then the Servomotor will enter a coasting state.
Refer to the following section for information on stopping methods other than those for over-
travel.
