ASDA Series Application Note
3.4 Printing Machine Application with Synchronization of
Multiple Axes

3.4.1 Description

This section mainly describes the position synchronization application for shaftless color process
printing. In this application, the position error is not compensated by ASDA-A2, but the host
controller by sending the signal for position synchronization.

3.4.2 System Operation and Configuration

3.4.2.1 How to Configure Your System

When applying shaftless printing machine, position of all printing rollers have to be synchronized.
If any of the printing rollers is deviated, position correction and compensation is needed. It can
be done by E-Cam and PR overlap function provided by ASDA-A2. In this application, ASDA-A2
is unable to judge the compensation time and the amount it needs to compensate for the
deviated position; however, it can control the synchronization of all printing rollers.
Passing on the pulse from master axis
Master axis needs to command the slave axis by passing on the pulse (for moving the material).
Each axis has to be set with the function of pulse sending. The delay time set on each axis is 50
ns and will not weaken the signal strength.
EV1 position compensation
When EV1 is triggered by the controller, it will call the corresponding PR. This PR will execute
one incremental command and complete the command with the speed higher than synchronous
