SINAMICS S120 drive system
Measuring systems
Overview
S/R = signals/revolution
Power supply
The measuring systems only fulfil the requirements stipulated
in the standard IEC 61010-1 if the power is supplied from a
secondary circuit with limited power according to
IEC 61010-1
3rd Ed.
, Section 9.4 or with limited power according
to IEC 60950-1
2nd Ed.
, Section 2.5, or from a secondary circuit
Class 2 according to UL1310. You can also use the correspond-
ing sections of the standards DIN EN 61010-1, EN 61010-1,
UL 61010-1 and CAN/CSA-C22.2 No. 61010-1 instead of the
standard IEC 61010-1
3rd Ed.
, Section 9.4, respectively the
corresponding sections of the standards DIN EN 60950-1,
EN 60950-1, UL 60950-1 and CAN/CSA-C22.2 No. 60950-1
instead of the standard IEC 60950-1
2nd Ed.
, Section 2.5.
