Figure 135 - Internal Interruption - Position Command
Integration for internal interrupt of an absolute position command (ABS) is
slightly different from what described in Position Control Command
on
page 269. The way REL and INC commands work is the identical. The target
position is the previous target position plus the current. See the example below.
