Input (NOT).
Explanation of Settings
Set value
0 An error will occur if both the positive and negative drive prohibition inputs are open at the same
time.
1 Positive drive prohibition input and negative drive prohibition input disabled.
2 An error will occur if either the positive or the negative drive prohibition input is open.
• Install limit switches at both ends of the axis to prohibit the motor from traveling in the direction where
one of the switches operates. This can be used to prevent the workpiece from traveling too far and
thus prevent damage to the machine.
• When the object is set to 0, the operation is as follows:
Positive Drive Prohibition Input (POT) closed: Positive limit switch not operating and status normal.
Positive Drive Prohibition Input (POT) open: Positive direction prohibited and negative direction
permitted.
Negative Drive Prohibition Input (NOT) closed: Negative limit switch not operating and status
normal.
Negative Drive Prohibition Input (NOT) open: Negative direction prohibited and positive direction
permitted.
• If this object is set to 0, the motor decelerates and stops according to the sequence set in the Stop
Selection for Drive Prohibition Input (3505 hex). For details, refer to explanation for Stop Selection for
Drive Prohibition Input (3505 hex).
Precautions for Correct Use Precautions for Correct Use
• If this object is set to 0 and the positive and negative prohibition inputs are both open, a Drive
Prohibition Input Error (Error No. 38.0) will occur because it is taken that Servo Drive is in error
condition.
• If this object is set to 2, a Drive Prohibition Input Error (Error No. 38.0) will occur when the
connection between either the positive or negative prohibition input and COM is open.
