Notes
1. When DI30 to DI37 of connector CA40 are allocated as the
DIs used for the axis selection and multiplier setting, DI30
to DI37 of connector CM17 cannot be used.
2. One DO is available for the manual pulse generator side at
the user’s discretion. When this is used, DO37 of CM17
cannot be used, as in the case for DIs above.
3. This function may not be applicable depending on the type
of CNC connected. Be sure to check before using.
