The
electronic motor managers (EMMs), among
other things, serve for motoring a drive
system or a 3 – phase load. For this, 3
currents have to be measured and
monitored. Currents of more than 5 A
cannot be processed by the EMM current
measuring input. Therefore, separate
current X’mers has to be installed
before the current measuring input so
that the primary current is transformed
into 5 A maximum.
