the Servomotor rotating (Pin No. is allocated in the default settings).
• You can stop the Servomotor from rotating beyond the device's movement range by connecting a lit
input.

Stopping Methods when Forward/Reverse Drive Prohibit is OFF
Pn001.1
POT (NOT) is OFF
"1" or "2"
Note 1. If the Servomotor stops in this mode during position control, the position loop is disabled.
Note 2. The position method used during torque control depends on Pn001.0 setting (the P001.1
setting is unrelated).
Note 3. With a vertical load, the load may fall due to its own weight if it is left at a drive prohibit input.
We recommend that you set the stop method for the drive prohibit input (Pn001.1) for decel-
erating with the emergency stop torque, and then set stopping with the servo locked (SV: 1)
to prevent the load from falling.
4-78
You must allocate both POT and NOT.
Note: As the default setting, they are allocated
to CN1 pins 7 and 8.
Set the stop method when POT and NOT in
Pn001.1 (stop selection for drive prohibition
input) are OFF.
If Pn001.1 is set to 0 (stop according to
Pn001.0 setting), be sure to set Pn001.0 (stop
selection for alarm generation with Servo OFF).
If Pn001.1 is set to 1 or 2, set emergency stop
torque in Pn406.
