FE
Maximum following error threshold set.
Description

Syntax
This command is used to set the maximum allowed following (tracking) error threshold for an

axis. This error is defined as the difference between the real (encoder) position and destination
(target) position of a motion device. The real position is the one reported by the position
sensing device (i.e., quadrature encoder).
If following error checking is enabled (see ZH command) and the following error exceeds the
maximum threshold specified with this command, the controller will automatically disable
closed-loop positioning (see MM command). Also, the positioning units must be set to
'Counts' in order for following error tracking and closed-loop correction to take effect (see SN
command).
NOTE: Following error checking must be enabled (see ZH command) in order for FE
