I/O Availability and
Specifications
All Ultra3000 drives and Kinetix 5100 drives have a comprehensive set of
digital I/O and analog I/O. Use this section to verify if the I/O functionality is
comparable.
Digital Inputs
Table 19 compares the digital inputs of the Ultra3000 drives and the Kinetix
5100 drives.
Kinetix 5100 drives have eight inputs with configurable functions and two
high-speed inputs. The standard digital inputs on Kinetix 5100 drives have the
same physical characteristics. Table 20
and Table 21 compare the digital inputs
physical characteristics between Ultra3000 and Kinetix 5100 drives.
