Chapter 6 Motion Function Blocks
6-80
(1) This motion function block performs phase correction of axis during synchronous control operation. Phase correction is
performed on the main-axis position referred to by sub-axis in synchronous control operation, to perform synchronous
control operation of the sub-axis to the corrected main-axis position.
(2) Once phase correction command is executed, the current position of the main-axis is phase-corrected using the phase shift
setting at PhaseShift- Velocity / Acceleration /Deceleration / Jerk.
(3) Phase correction does not change the actual command position or current position of the main-axis. Phase correction is
performed on the main-axis position referred to by sub-axis in synchronous control operation. In other words, the main-axis
does not know that phase correction is executed by the sub-axis.
(4) Phase correction of the same amount can be performed again from the current position by re-executing the function block
(Execute input is on) before the command is completed. In other words, phase shift is a relative value from the execution
point.
(5) After executing phase correction command, when the phase shift is reached, Done output is on.
