Operating the XtraDrive Using XtraWare
4.9. ECAM (Electronic Cam)
Cam creates motion according to a specified profile, depending either on the
position of a master axis or on time elapsed. The ECAM feature allows you
to specify the position that a slave axis must reach, depending on the
position of a master axis or on the time elapsed.
The XtraDrive allows up to four profiles to be specified per project. Each
profile can be comprised of a maximum of 16 segments, and may contain
up to 256 data points.
4.9.1. ECAM Profile Characteristics
The following must be considered when designing a profile:
♦ Up to four different profiles can be defined simultaneously.
♦ Each profile can be divided into a maximum of 16 segments.
♦ An ECAM table may contain up to 256 data points. To avoid exceeding
this limit, do not specify unnecessarily small Master Step values.
♦ The maximum slave step is 32767 user position units.
The maximum master step (after scaling) is 32767 counts.
4.9.2. Installing ECAM
To enable the ECAM functionality, see the document Instructions for
License Setting.
4.9.2.1. Verifying that ECAM is Installed
¾ To verify that ECAM is installed:
1. Open XtraWare.
2. From the Communication menu, select On-Line to enter on-line mode.
3. Click Upload Project
to upload a project from the XtraDrive.
4. Open the File menu.
If the Download Cam option in the File menu is enabled, the installation
was successful.
4.9.3. ECAM Workflow
When working with ECAM, the following process is followed:
♦ Designing the ECAM Profile:
You define the profile using XtraWare.
XtraWare automatically generates a Master-Slave table.
The Master-Slave table is downloaded to the XtraDrive.
