Spindle Synchronization
Chapter 15
15-3
Function
This parameter determines the follower spindle for a synchronized pair.
Use the spindle number to define this parameter. Spindle numbers are
identified by the Spindle Type for Axis parameter (refer to page 7-103 for
more information about this parameter).
During synchronization, commands to the controlling spindle
(i.e., programmed spindle speed and direction) are mimicked by the
follower spindle.
Important: When configuring your spindles, make sure they are given
separate, definitive spindle parameters. If one spindle is defined as the
controlling spindle as well as the follower spindle, the control will assume
you are trying to synchronize a spindle to itself and you will receive the
error: SYNCH SPINDLES MISCONFIGURED.

(a) None
(b) Spindle 1
(c) Spindle 2
(d) Spindle 3
Notes
This is a global parameter. The value set here applies to both spindles.
To accommodate for the difference in gear ranges for the controlling and
follower spindles, AMP takes the lowest maximum and the highest
minimum gear ranges of the follower spindle to create the available gear
range. While the follower spindle is ramping to the required spindle speed,
a warning will appear, warning you that you have bypassed the minimum
or maximum RPM.
