CAUTION: Renishaw encoder systems have been designed to the relevant EMC standards, but must be correctly integrated to achieve EMC compliance. In particular, attention to the shielding
arrangements is essential. For UHV cables ensure that the cable to UHV connector termination meets the EM requirements defined by IEC 61800-5-2: Annex E second environment.
Original instructions
5 V ±10% Readhead only < 100 mA
T4xx1 with Ti0000 < 100 mA
T4xx1 with DOP < 275 mA
Current consumption figures refer to unterminated systems.
For digital outputs a further 25 mA per channel pair (eg A+, A−) will be drawn when terminated with 120R.
For analogue outputs a further 20 mA in total will be drawn when terminated with 120R.
Power from a 5 V dc supply complying with the requirements for PELV of standard IEC 60950-1.
