SIMOVERT MASTERDRIVES
The following connections are provided on the control terminal strip:
♦ 10 V aux. voltage (max. 5 mA) for the supply of external
potentiometers
♦ 2 serial interfaces SCom1 and SCom2 (USS / RS485)
Terminal Designation
23 P10 V
24 N10 V
25 RS485 P (SCom2) USS bus connection SCom2
26 RS485 N (SCom2) USS bus connection SCom2
27 RS485 P (Scom1)
28 RS485 N (Scom1)
Connectable cross-section: 0.14 mm
The terminals 23 and 24 are short-circuit proof.
Terminal 23 is at the top when installed.
Table 7-6 Control terminal strip X103
Either an OP1S or a PC can be connected up via the 9-pole SUB D
socket.
The 9-pole SUB D socket is internally coupled with the USS bus, with
the result that it is possible to exchange data with further converters
and inverters which are linked via the USS bus.
