Basic converter The USS protocol (universal serial interface) is implemented on the

interface SCom1 basic converter interface SCom1.

The following documentation is available depending on the particular application of the SCom1 basic converter interface:

♦Connection of a PC / PG with DriveMonitor software for start- up/servicing/operation:

The documentation is provided on DriveMonitor CD in files BEDANLTG.TXT (ASCII format) and BEDANLTG.WRI (WRITE format).

♦Connection of higher-level PLCs with USS protocol:

SIMOVERT MASTERDRIVES

Application of serial interfaces with USS protocol Order No.: 6SE7087-6CX87-4KB0

Additional general comments regarding connection and parameterization:

Connection: See Section "Control terminals"

NOTE

NOTE

A communication link can be made either via the terminal strip on the CU -X100 (RS485 Standard) or the interface connection on the PMU -X300 (9-pin SUB D connector / RS232 or RS485 (V24)).

Only one of the above possible connections may be used!

A four-wire connection can be implemented when the SCom2 is connected via the terminal strip (-X100) on the CUSA board. Switchover between two-wire and four-wire connection is automatic.

The bus terminations (150 Ω in total) must be set for the last bus station (slave). For positioning of jumpers on S1, see Fig. 7-9.

SCom1: Close jumpers S1.1 and S1.2 of DIP-FIX S1 on the CUSA.

Dual-port Ram (DPR for SCB, TSY, CB, TB)

The dual-port RAM is the internal interface on the CUSA (-X107) for connection of option boards via the LBA (Local Bus Adapter, option) of the electronics box.

Available option boards:

♦TSY (Tachometer and Synchronization Board)

♦TB (Technology Board)

♦SCB (Serial Communication Board)

♦CB (Communication Board)

For further information about connecting option boards and parameterizing the interface, see also the operating instructions for the relevant boards.

For additional information, see Section "Control and status words".
