Typical SDE (analogue)
Renishaw encoder systems have been designed to the relevant EMC standards, but must be correctly
integrated to achieve EMC compliance. In particular, attention to shielding arrangements is essential.
ATOM
linear installation guide
ATOM readhead typically <50 mA
ATOM with ACi typically <100 mA
ATOM with Ri typically <100 mA
ATOM with Ti typically <200 mA
NOTE: Current consumption figures refer to unterminated systems.
For analogue outputs a further 10 mA in total will be drawn when terminated
with 120R. For digital outputs a further 25 mA per channel pair (eg A+, A-)
will be drawn when terminated with 120R.
