Type
Input
A circuit example for when the SEN signal is allocated to CN1-40 to CN1-46 on the I/O signal
connector is provided below.
Refer to the following section for the procedure to allocate input signals.

Signal Status
Does not request the position data from the absolute
OFF (open) linear encoder. (This is the status after the power sup-
ply is turned ON.)
Requests the position data from the absolute linear
