The following shows the differences in synchronous control functions between the
Motion controller Q172DCPU (SV22) and Simple Motion module
QD77MS/QD77GF/LD77MS/LD77MH.
The whole system is switched to the
virtual mode by turning ON the
real/virtual mode switching request bit.
The whole system is switched to the real
mode by turning OFF the real/virtual
mode switching request bit.

Appendix - 2
QD77MS/QD77GF/LD77MS/LD77MH
The control is started for each axis by
turning ON the synchronous control start
bit for each axis.
The control is stopped for each axis by
turning OFF the synchronous control
start bit of each axis.
Total 3 axes of main shaft (2 axes) and
auxiliary input (1 axis)
None
(It can be substituted by the servo input
axis setting to the virtual servo amplifier.)
Use the servo amplifier as the drive
module (input axis).
(It is possible to use without connecting
the servo amplifier by setting to the
virtual servo amplifier.)
