3 System Overview
3.1
General
The cable transducer is a linear measuring system with a CANopen interface. It supports scaling and presetting.
In consideration of “CAN in Automation” (CiA) Profile 406 for Encoders, it’s an absolute linear encoder - Class C2
(exception diagnostic part). It has also the possibility to implement inclination sensors, in according to CiA) Profile 410
for Inclinometers.
3.2
Supported Profiles
Following CANopen profiles are supported:
CiA 301 / Version 4.1 (Communication)
CiA 305 / Version 1.0 (LSS)
CiA 406 / Version 3.2 (Encoder Profile)
o
Absolute encoder redundant with cable-pull: Absolute linear encoder
CiA 410 / Version 1.0 (Inclinometer Profile)
3.3
Supported CANopen Services
Following CANopen services are supported:
1 Network Management (according to CiA 301)
1 SDO Server (according to CiA 301)
2 TPDOs (according to CiA 301/CiA 406/ CiA 410)
1 Emergency Producer (according to CiA 301/CiA 406/ CiA 410)
1 Heartbeat Producer (according to CiA 301)

Scaling
The step size for all position objects can be adapted in the object 0x6005. The basic unit is nanometer
Example 1: A position step s
etting of 1’000’000 nm/step means that the position output unit is 1mm.
