[ b ] Selecting Motor Stopping Methods for Overtravel
When using the overtravel function has been enabled, the following parameters are used to set the methods for stopping
the motor. Select the methods for stopping when the P-OT or N-OT is input during motor running.

Item
Enables use of Positive Prohibit Input Signal
(P-OT). (Forward rotation prohibited when
open, allowed for 0 V.)
Disables use of Positive Prohibit Input Signal
(P-OT). (Forward rotation always allowed.)
Enables use of Negative Prohibit Input Signal
(N-OT). (Reverse rotation prohibited when
open, allowed for 0 V.)
Disables use of Negative Prohibit Input Signal
(N-OT). (Reverse rotation always allowed.)
Item
Uses the same stopping method as for Servo
OFF.
Stops the motor according to Cn-01 bit 6 set-
ting (dynamic brake or coasting) when over-
travel is detected.
Decelerates the motor to a stop by applying the
torque specified in Cn-06 (EMGTRQ Emer-
gency Stop Torque) when overtravel is
detected.
Decelerates the motor to a stop and then turns
OFF the Servo.
Decelerates the motor to a stop and then sets it
in the zero-clamp mode.
Stops the motor by applying dynamic brake
(DB).
Makes the motor coast to a stop.
Current is not supplied to the motor and the
machine stops due to friction.
Stops the motor by applying dynamic brake
(DB) and then releases the DB.
Stops the motor by applying dynamic brake
(DB) and then holds the DB.
