Explanation of Set Values
Set value
0 Forward drive prohibition input and reverse drive prohibition input enabled.
1 Forward drive prohibition input and reverse drive prohibition input disabled.
2 Forward drive prohibition input and reverse drive prohibition input enabled.
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.
Operation will be as follows if 0 is set.
· Forward drive prohibition input (POT: CN1 pin 9) and COM connected: Normal status when
the forward limit switch does not operate
· Forward drive prohibition input (POT: CN1 pin 9) and COM open: Forward direction prohibited
and reverse direction permitted
· Reverse drive prohibition input (NOT: CN1 pin 8) and COM connected: Normal status when
the reverse limit switch does not operate
· Reverse drive prohibition input (NOT: CN1 pin 8) and COM open: Reverse direction prohibited
and forward direction permitted.
If this is set to 0, the Servomotor will decelerate and stop 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).
If this parameter is set to 0 and the forward and reverse prohibition inputs are both open, an error
will be detected in the driver, and a drive prohibition input error (alarm display No. 38) will occur.
If this parameter is set to 2, a drive prohibition input error (alarm display No. 38) will occur when
the connection between either the 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
will be eliminated, and there may be repeated vertical movement of the workpiece. If this occurs,
set the Stop Selection for Drive Prohibition Input (Pn505) to 2 or perform limit using the Host
Controller rather than using this function.

range
Explanation of Set Values
Set value
During deceleration: Dynamic brake operation
0 After stop: Torque command is 0 for drive prohibition direction
Error counter: Held
During deceleration: Torque command is 0 for drive prohibition direction
1 After stop: Torque command is 0 for drive prohibition direction
Error counter: Held
During deceleration: Immediate stop
2 After stop: Torque command is 0 for drive prohibition direction
Error counter: Clear before and after deceleration
Set the drive conditions during deceleration or after stopping after the drive prohibition input (POT:
CN1 pin 9 or NOT: CN1 pin 8) is enabled.
If this is set to 2, the Immediate Stop Torque (Pn511) will be used to torque limit during
deceleration.
