Spindle Synchronization
Chapter 15
15-5
Function
This parameter determines whether reversed rotation is required on the
follower spindle to synchronize with the controlling spindle. This
parameter also determines if orient angles are reversed (after the zero
points are designated on both spindle markers, 45 degrees on controlling
= 315 degrees on follower). For information on configuring the zero point,
refer to page 15-7.
When configuring Normal follower orientation, an M03 (CW) returns an
M03. When configuring Reversed follower orientation, an M03 (CW)
returns an M04 (CCW). In the figure below, the spindles are using
Reversed follower orientation, where spindle A is programmed with an
M03, while spindle B is programmed with an M04.
