Operating Functions
5-6 Forward and Reverse Drive Prohibit
Function
• When the Forward Drive Prohibit Input (POT: CN1 pin 9) and Reverse Drive Prohibit Input (NOT:
CN1 pin 8) are turned OFF, the Servomotor will stop rotating.
• You can stop the Servomotor from rotating beyond the device's operating range by connecting
limit inputs.
Parameters Requiring Settings
Operation
Stopping Methods When Forward/Reverse Drive Prohibit Is OFF
While the Forward Drive Prohibit Input (POT) is OFF, the Servomotor cannot be driven in the
forward direction, but it can be driven in the reverse direction. Conversely, while the Reverse Drive
Prohibit Input (NOT) is OFF, the Servomotor cannot be driven in the reverse direction, but it can be
driven in the forward direction.
With a vertical axis, there is a risk that the load may drop when drive is prohibited by the drive
prohibit input. To prevent this, it is recommended that the deceleration method be set to use
emergency stop torque in the Drive Prohibit Input Stop Selection parameter (Pn066), and that
stopping in the servo-lock state be set (set value: 2).
