Point of change in the signal input to the receiver (threshold)
When the input signal state changes from the low level to high level,
the signal level must rise to 3.7 V or higher.
When the input signal state changes from the high level to low level,
the signal level must fall to 1.5 V or lower.

NOTE
1 When Xm+1.5 to Xm+2.5 of connector JA58 are
allocated as the Dis used for the axis selection and
multiplier setting, Xm+1.5 to Xm+2.5 of connector
CM68 cannot be used.
2 One DO is available for the manual pulse generator
side at the user's direction. When this is used,
Yn+5.3 of CM68 cannot be used, as in the case for
DIs above.
