5 Parameter Setting and Functions
5.3.2 Overtravel
(2) Changing Input Signal Settings
The settings of the input signals for overtravel can be changed with the parameters below.
PnB0F
PnB10
Note: During the overtravel state or software limit state, the servomotor is not positioned to the target position specified by
the controller. Check the current position to confirm that the axis is stopped at a safe position.
(3) Motor Stopping Method When Overtravel is Used
Set the following parameter to specify the motor stopping method when overtravel is used.
Overtravel
PnB1F
Set the deceleration rate when decelerating to a stop in PnB2B.
PnB2B
5-6
Parameter
0
When input signal is OFF (open), forward run is prohibited (forward
[Factory setting] overtravel).
When input signal is ON (close), forward run is prohibited (forward
1
overtravel).
2 Forward run is always prohibited (forward overtravel).
3 Forward run is always enabled. (P-OT signal is not used.)
0
When input signal is OFF (open), reverse run is prohibited (reverse
overtravel).
[Factory setting]
When input signal is ON (close), reverse run is prohibited (reverse
1
overtravel).
2
Reverse run is always prohibited (reverse overtravel).
3
Reverse run is always enabled. (N-OT signal is not used.)

stop
PnB1F = 2
Decelerate to
a stop
Parameter
0
Stops motor by the same method as when servo is turned OFF
[Factory setting] according to Pn001.0 setting.
1
Stops motor immediately, and then changes motor state to servo lock.
Decelerates motor to a stop at deceleration rate set with PnB2B, and
2
then changes motor state to servo lock.
Deceleration
Setting Range
1 to 99999999
If the servo turns OFF due to overtravel, the servo will not turn ON even if the overtravel
is released. To turn ON the servo, turn the /S-ON signal OFF and then ON or send the
SVON serial command. If parameter PnB0E is set to 2 to keep the /S-ON signal always
ON, turn the power supply OFF and then ON again.
