Compat- Precautions for
ibility replacement
• On the QD75P2 the
manual pulse generator
cannot be used
independently on each
axis. If the manual pulse
generator must be
connected to each axis,
use the 1-axis module.
• The A0J2D71 and
QD75P2 differ in the
specifications of manual
pulse inputs, so before
connecting a manual
pulse generator to the
QD75P2, confirm the
specifications of the
pulse generator.
• If not using the unit
pulse on the QD75P2,
the magnification from
the pulse input from the
manual pulse generator
will become smaller.
QD75P2 has no M code

comment function.
The QD752P2 does not
have the error
compensation function.
Use the electronic gear
function instead.
At default, the limit check is
on.
