• Positive direction over-travel inhibit input.
• The operation with this input turned ON is set up in Pr5.04 “Setup of over-travel inhibit
input”.
• When using this input, set Pr5.04 “Setup of over-travel inhibit input” to a value other than 1
so that the input is OFF when the moving portion of the machine exceeds this signal range
toward positive direction.

• Negative direction over-travel inhibit input.
• The operation with this input turned ON is set up in Pr5.04 “Setup of over-travel inhibit
input”.
• When using this function, set Pr5.04 “Setup of over-travel inhibit input” to a value other
than 1 so that the input is OFF when the moving portion of the machine exceeds this signal
range toward negative direction.

• Clears the positional deviation counter.
• Default setup clears the counter at the rising edge of the clear input, To change the setup,
modify it in the Pr5.17 “Counter clear input mode”.

This function can be assigned to only SI7. Allocation of this function to any other pin will
cause an error.
