6.2.2 Parameter Settings
This section describes the parameter settings for overtravel.
Enabling or Disabling Overtravel Input Signals
The following parameters are used to enable or disable the overtravel input signals.
Setting Precautions
• These parameters are disabled when self configuration is performed.
Selecting Motor Stopping Methods for Overtravel
When overtravel is used, the following parameters are used to set the method for stopping the
motor. Select the method for stopping when the P-OT or N-OT is input while the Servomotor is
running.
Parameter Description Setting Item Default
Pn50A.3
P-OT Signal
Mapping
1 (recom-
mended)
This setting enables the use of the Forward Run
Prohibited signal (P-OT). (Positive rotation prohib-
ited when open or allowed at 0 V.)
1
8 This setting disables the P-OT signal.
Pn50B.0
N-OT Signal
Mapping
2 (recom-
mended)
This setting enables the use of the Reverse Run
Prohibited signal (N-OT). (Negative rotation pro-
hibited when open or allowed at 0 V.)
2
8 This setting disables the N-OT signal.
Parameter Description Settings Item Default
Pn001.1
Overtravel Stop
Mode
0 (recom-
mended)
This setting stops the Servomotor with the
same stop method that is used when the Ser-
vomotor is turned OFF (based on the setting of
Pn001.0).
0
1
This setting decelerates the Servomotor to a
stop by applying the specified torque when
overtravel is detected, and then sets it to Zero
Clamp (Servo Lock) Mode. (Specified torque:
Pn406 (Emergency Stop Torque))
2
This setting decelerates the Servomotor to a
stop by applying the specified torque when
overtravel is detected, and then sets it to free-
run mode. (Specified torque: Pn406 (Emer-
gency Stop Torque))
Pn001.0
Servomotor Power
OFF Stop Mode
0 (recom-
mended)
This setting stops the Servomotor by applying
the dynamic brake (DB). The DB is held after
stopping.
0
1
Stops the Servomotor by applying the dynamic
brake (DB), and then releases the DB and puts
the Servomotor into Free-run Mode.
2
This setting makes the Servomotor free-run to a
stop.
The Servomotor is turned OFF. The machine
stops due to friction.
