Precautions for Correct Use
Precautions for Correct Use
Both signals are disabled (in a state in which drive prohibition will not operation) in the default
settings. If prohibiting the drive input is required, set the Drive Prohibit Input Selection (3504 hex)
to either 0 or 2. The setting on the Input Signal Selection 1 to 8 (3400 to 3407 hex) can change
the logic and allocation for the respective Input terminals (CN1 to 7 and 8).
z
Stop Selection for Drive Prohibition Input (3505 hex)
Set the deceleration and stop methods upon a positive or negative drive prohibition input.
*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.

Prohibition Input (3505 hex).
*1
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.
1
Positive drive prohibition input and negative drive prohibition input disabled.
2
