Input Connection Example
Input Signal
This section shows connection examples of the forward/reverse direction limit input, origin
proximity input, origin input, interrupt input, emergency stop input and encoder input.
There are an N.O. input or N.C. input for an input. You can use either type by setting axis
parameters. For details, refer to "I/O Function Setting" on page 5-18.
Forward direction limit input
Reverse direction limit input
Origin proximity input
Origin input (24 V)
Interrupt input
Emergency stop input
General-purpose input
Positioning completed input
Drive alarm input
If the switch capacity is small, it may damage the switch. For each input, connect a switch whose
Use a proximity sensor or other chatter-free sensor for the origin input (24 V).
If the signal width of the forward/reverse direction limit input is small, the axis movement may stop
switch capacity is at least 5 mA.
proximity input or forward/reverse limit input changes from ON to OFF is used as the timing for the
origin detection. In this case, use a proximity sensor or other chatter-free sensor for the input.

at a position beyond the signal detection position upon limit input. In this case, the limit input may
not function as intended after the reset. Provide a sufficient signal width for the forward/reverse
direction limit input.
Depending on the setting of the origin search operation pattern, the point at which the origin
If you use a switch with contacts, the origin position may deviate due to chattering. For information
