Set the operation of the Positive Drive Prohibition Input (POT) and the Negative Drive Prohibition
Input (NOT).
Explanation of Settings
•
Install limit switches at both ends of the axis to prohibit the Linear Motor from driving in the direction
specified by the switch. This can be used to prevent the workpiece from driving too far and thus
prevent damage to the machine.
•
When the object is set to 0, the operation is as follows:
•
If this object is set to 0, the Linear 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).
Additional Information
•
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) 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) will occur when the
connection between either the positive or negative prohibition input and COM is open.
For details, refer to 7-2 Positive and Negative Drive Prohibition Functions on page 7-8.
