When carrying out a position follow-up control (synchronous operation) by
synchronous encoder, delays in the progresses, etc. cause the phase to deviate at
servomotor shaft end in respect to the synchronous encoder. The phase compensation
function compensates in this case so that the phase does not deviate.
(1) Parameter list
Set the following devices for axes to execute the phase compensation function.
(Set in the output module parameter.)

(Note-1): D800 to D1559 are dedicated devices of virtual servomotor axis, synchronous encoder
axis and output module "Cam" in the virtual mode.
Unused areas of virtual servomotor axis and cam axis can be used as a user device.
(Note-2): Set an even number at the first device.
(Note-3): "p" indicates the user setting area points of the Multiple CPU high speed transmission
area for each CPU.
(Note-4): The range of "PXn+4 to PXn+F" cannot be used (fixed at 0) for the input device (PXn+0
to PXn+F) allocated to the built-in interface in Motion CPU (DI). (n: First input No.)
(Note-5): "M4000 to M4639 and M4800 to M5439" are the dedicated devices of virtual servomotor
axis in the virtual mode.
Unused area of virtual servomotor axis can be used as a user side.
(Note-6): Only device of the self CPU can be used.
