8-6 Extended Parameters
Set the operation of the Forward drive prohibition input (POT) and the Reverse drive prohibition
input (NOT).
Refer to "6-2 Forward and Reverse Drive Prohibition Functions (P.6-6)".
Explanation of Set Values
Install limit switches at both ends of the axis to prohibit the motor from traveling in the direction
specified by the switch. This can be used to prevent the workpiece from traveling too far and thus
prevent damage to the machine.
When the parameter is set to 0, the operation is as follows:
• Forward drive prohibition input (POT) shorted: Forward limit switch not operating and status
normal.
• Forward drive prohibition input (POT) open: Forward direction prohibited and reverse direction
permitted.
• Reverse drive prohibition input (NOT) shorted: Reverse limit switch not operating and status
normal.
• Reverse drive prohibition input (NOT) open: Reverse direction prohibited and forward
direction permitted.
If this is set to 0, the Servomotor decelerates and stops according to the sequence set in the Stop
Selection for Drive Prohibition Input (Pn505) For details, refer to explanation for Stop Selection for
Drive Prohibition Input (Pn505).
