voltage for the encoder and microprocessor circuitry is 24 VDC.
In an emergency-stop situation, where an approved relay has
cut-off the main power, encoder position and other values are
maintained by this control voltage. Alternatively, there is an absolute multiturn encoder instead, which does not need supply or
even a backup-battery. Its graphical programming environment is
designed with industrial end-users in mind. No matter the number
of input-output points in the actual motor, each can be used in
the program and easily set.

Nanocrystalline chokes that deliver higher power ratings in a
small size, and surface mount power inductors with compact
footprints, are among new products that ITG Electronics has
developed for power electronics designers recently.
The company now offers a range of nanocrystalline common
mode chokes with its DCN series, C20530 series, C20540
series, C30530 series and C30540 series, pictured in the top two
photos. Nanocrystalline material gets its name from its producWLRQSURFHVVH[SODLQV0DUWLQ.XRGLUHFWRURIIXWXUHIRU,7*
