9.4.5 Phase correction control
Phase correction control is the function that performs correcting phase for executing synchronous
control of main axis. While acting synchronous control, it executes virtual positioning move (correcting
phase) about the main axis position being synchronized with sub-axis. So the sub-axis executes
synchronous control about position of the moved main-axis.

Features of control
(a) Phase correction command can be executed about axis being synchronous operation
such as speed synchronous or CAM control.
(b) Although the phase correction command is executed, the position of the command for
main axis and the current position don’t change. When operating synchronous control for
sub-axis, phase correction is executed with calibrated value for main axis position to refer.
(c) The position of main-axis referring sub-axis with synchronous operation will be set “real
main-axis po phase correction control position”.
(d) The phase correction speed is operated by relative velocity for the currently main-axis
speed.
(e) Trapezoid or s-curve operation is executed by the acceleration or deceleration patterns
of main-axis.
(f) In case main-axis is encoder, when execute the phase correction control it is executed by
using speed limit and the acceleration or deceleration patterns of sub-axis.
(g) When command is re-executed with operating phase correction, the phase correction is
executed as much as correcting size at that point. In other words, phase correction amount
is additional operations as a relative value.
(h) When phase correction size is set as 0 with re-executing phase correction, existing
operation will stop directly. (The phase correction operation status change to Off)
