The example in the illustration on the previous page has been greatly simplified. In actual
operation, each register can be controlled from the user program.

Set the phase control mode to ON.
Set Phase Reference Generation
Operation Disable to OFF.
Driver RUN command (RUN)
When MB01010 turns ON, phase con-
trol starts.
Set the reference speed reference
(NREF).
The speed reference is stored in
advance in MW01010. The gear ratios
are stored in advance in MW01020 and
MW01021. If gears are not required, “1”
is stored in advance.
To move the phase, set the phase com-
pensation (OLC016). The distance to be
moved (the angle of rotation of the
motor axis converted to the number of
pulses) is stored in advance in
ML01012.
