SIMOVERT MASTERDRIVES
The SCB1 (Serial Communication Board 1) supplements converters of
the SIMOVERT MASTERDRIVES series by providing
♦ the terminal-strip expansion "serial I/O system" (analog and digital),
with the SCI1 or SCI2 boards, or with
♦ a peer-to-peer connection for fast transfer e.g. of setpoints between
various converters.
Information is transferred, floating, via fiber-optic cables.
In order to connect the SCB with the CU control board, the local bus
adapter (LBA) (MRPD 6SE7090-0XX84-4HA0) in the electronics box is
used.
The SCB is used as a master, and can be connected with up to 2 SCI
boards, operating as slaves, via fiber-optic cable.
Several converters are connected in a multi-motor drive to create a fast
setpoint cascade, for example, or are connected serially via the SCB
board for common switch-on.
