SIMOVERT MASTERDRIVES Compendium Motion Control 8.1-21
In the SIMOVERT MASTERDRIVES MC series, the control electronics
board, CUMC (Control Unit Motion Control), CUPM (Control Unit
Motion Control Performance 2), CUMP (Control Unit Motion Control
Compact PLUS Performance 2), CUVC (Control Unit Vector Control) or
CUVP (Control Unit Vector Control Compact PLUS) is used. Depending
on the type of basic unit, it has at least one serial interface with the
USS protocol. The following table shows the available interfaces:

Table 8.1-9 Interfaces on the CU board
All the interfaces on the CU boards are non floating (not electrically
isolated).
The SCB2 (Serial Communications Board) is an expansion board of the
SIMOVERT MASTERDRIVES. The board has a floating RS485
interface. Either the peer-to-peer protocol or the USS protocol can be
used at this interface.
The supplementary SCB2 board cannot be built into the Compact
PLUS type of unit.
