speed. This could correct the relative position by promptly accelerating or decelerating the
printing roller while it is still synchronized with the master axis.
3.4.2.2 Analysis of System Operation
When the system works normally, all slave axes follow the master with the same speed.
Figure 3.4.2 Normal operation of the system
When the host controller detects any of the axes is left behind, it will send EV1 signal. This is for
urging the left-behind axis to move quickly and adjusting its position.

3.4.3 Servo System Setting
3.4.3.1 PR Procedure and E-Cam Curve
Master axis shall synchronize with slave axis. Both will be in linear relationship. The slave axis
has to issue a PR with incremental command which connecting to this event (e.g. EV1). When
the event is triggered, it will execute the corresponding PR command and start to compensate
