(2) Wiring the hardware stroke limit
When using the hardware stroke limit function, wire the terminals of the AD75
upper/lower limit stroke limit as shown in the following drawing.

(3) Precautions during control
(a) If the machine is stopped outside the AD75 control range (outside the
upper/lower limit switches), or if stopped by hardware stroke limit detection,
the "zero point return control", "main positioning control", and "advanced
positioning control" cannot start. To carry out these types of control again,
return the workpiece to the AD75 control range by a "JOG operation" or
"manual pulse generator operation".
(b) If the circuit between the RLS (lower limit signal) and COM, or between the
FLS (upper limit signal) and COM is open (including when not wired), the
upper/lower limit signal will turn OFF, and control with the AD75 will not be
possible.
(4) When the hardware stroke limit is not used
When not using the hardware stroke limit function, wire the terminals of the AD75
upper/lower limit stroke limit as shown in the following drawing.
