(3) Selecting the Motor Stop Method When Overtravel is Used
This is used to set the stop method when an overtravel (P-OT, N-OT) signal is input while the motor is operating.
* For details on stopping methods when the servo turns OFF or when an alarm occurs, refer to 9.6.4 Selecting the Stopping
Method After Servo OFF.

Meaning
Pn001 n.††00 Stop by dynamic
brake Dynamic Brake Stops the linear servomotor by applying dynamic
brake (DB), then holds it in Dynamic Brake Mode.
(Factory setting)
n.††01 Coast Coasts the linear servomotor to a stop, then places it
into Coast (power OFF) Mode.
n.††02 Coast to a stop Stops the linear servomotor in the same way as when
the servo is OFF (coasts to a stop), then places it into
Coast (power OFF) Mode.
n.††1† Decelerate to stop Zero Clamp Decelerates the linear servomotor with emergency
stop force (Pn406), then places it into Zero Clamp
(Servolock) Mode.
n.††2† Coast Decelerates the linear servomotor with emergency
stop force (Pn406), then places it into Coast (power
OFF) Mode.
• During force control, the linear servomotor enters DB Stop Mode or Coast Mode regardless of the setting of Pn001.1.
• After changing these parameters, turn OFF the main circuit and control power supplies and then turn them ON again to
enable the new settings.
• During n.††02 Coast Mode, SERVOPACK can be resumed using the servo ON signal.
„ TERMS
• Stop by dynamic brake: Stops by using the dynamic brake (with short-circuiting by a circuit of SERVOPACK).
• Coast to a stop: Stops naturally, with no brake, by using the friction resistance of the motor in operation.
• Decelerate to stop: Stops by using deceleration (braking) force.
• Zero Clamp Mode: A mode forms a position loop by using the position reference zero.

• This sets the stop force for when the overtravel signal (P-OT, N-OT) is input.
• The setting unit is a percentage of the rated force (i.e., the rated force is 100%).
• The value large enough to be the motor maximum force, 800% is set as the factory setting for emergency stop force.
However, the actual output emergency stop force is determined by motor ratings.
