Explanation of Set Values
• Install a limit switch at each end of the motor shaft to prohibit the Servomotor from being driven in the
direction corresponding to the switch that has been activated, thus preventing damage to the
machine due to a workpiece overrun.
• The function operates as follows when this parameter is set to 0:
• When Forward Drive Prohibition Input (POT: CN1 pin 9) and COM are connected: Normal state in
which the forward limit switch is not operating
• When Forward Drive Prohibition Input (POT: CN1 pin 9) and COM are open: Forward rotation
prohibited and reverse rotation permitted
• When Reverse Drive Prohibition Input (NOT: CN1 pin 8) and COM are connected: Normal state in
which the reverse limit switch is not operating
• When Reverse Drive Prohibition Input (NOT: CN1 pin 8) and COM are open: Reverse rotation
prohibited and forward rotation permitted
• When set to 0, the Servomotor decelerates and stops according to the sequence set in Stop
Selection for Drive Prohibition Input (Pn505). For details, refer to explanation for Stop Selection for
Drive Prohibition Input (Pn505).
• When set to 0 and if both the Forward and Reverse Prohibition Input signals are open, a Drive
Prohibition Input Error (Alarm No. 38) will occur.
• When set to 2, a Drive Prohibition Input Error (Alarm No. 38) will occur when the connection between
either Forward or Reverse Prohibition Input and COM is open.
• If a limit switch above the workpiece is turned OFF when using a vertical axis, the upward torque
decreases, and there may be repeated vertical movement of the workpiece. If this occurs, set Stop
Selection for Drive Prohibition Input (Pn505) to 2, or limit the operation using the host controller
instead of using this function.
