*1 If the Drive Prohibition Input Selection (3504 hex) is set to 2, a Drive Prohibition Input Error (Error No. 38.0) will
occur as soon as either the Positive or Negative Drive Prohibition Input becomes open. Therefore, regardless
of the set value, the subsequent operation will be performed according to the setting of the Fault reaction
option code (605E hex). In the same way, the Fault reaction option code (605E hex) takes priority when any
other error occurs.

Positive drive prohibition input and negative drive prohibition input enabled.
The operation when a signal is input is as follows.
• Positive drive prohibition input shorted: Positive limit switch not operating and status
normal.
• Positive drive prohibition input open: Positive direction prohibited and negative direction
permitted.
• Negative drive prohibition input shorted: Negative limit switch not operating and status
normal.
• Negative drive prohibition input open: Negative direction prohibited and positive direction
permitted.
The motor decelerates and stops according to the sequence set in Stop Selection for Drive
Prohibition Input (3505 hex).
If the positive and the negative prohibition inputs are both open, a Drive Prohibition Input
Error 1 (Error No. 38.0) will occur because it is taken that Servo Drive is in error condition.
Positive drive prohibition input and negative drive prohibition input disabled.
Positive drive prohibition input and negative drive prohibition input enabled.
If either the positive or the negative prohibition input is open, a Drive Prohibition Input Error
