1.3 General function description
The rotary measuring system
•
PSEN enc mx eCAM is an absolute multi-turn position measuring system with
synchronous serial interface (SSI).
•
PSEN enc sx eCAM is an absolute single-turn position measuring system with
synchronous serial interface (SSI).
The measuring system consists of a
redundant, dual-channel system
, in which
optical
and
magnetic sensing units
are arranged on a drive shaft, designed as a
hollow shaft or solid shaft.
1.3.1 Main features
●
SSI interface, to output data from measuring channel 1
●
SSI interface, to output data from measuring channel 2
●
Measuring channel 1:
-
Single-turn: optical single-turn sensing via code disk (transmitted light)
-
Multi-turn: optical single-turn sensing via code disk (transmitted light) and
magnetic multi-turn sensing
●
Measuring channel 2:
-
Single-turn: magnetic single-turn sensing
-
Multi-turn: magnetic single and multi-turn sensing
●
Additional incremental interface
●
Mechanically, the two systems are connected only by the common drive shaft and
the housing
●
Measuring channels have a common voltage terminal, but are electrically isolated
internally via two separate power supplies
●
A common drive shaft
●
2 Installation Types:
-
Hollow shaft version: PSEN enc m1 eCAM and PSEN enc s1 eCAM
-
Solid shaft version: PSEN enc m2 eCAM and PSEN enc s2 eCAM
The optical system has greater accuracy due to the technology.
The magnetic sensing system is a fully-fledged second measuring channel and
operates independently from the first measuring channel. The two measuring systems
have their own SSI interfaces, which transmit the same data format.
The data from measuring channel 1 is also output via an incremental interface.
