The USS protocol is parameterized at serial interfaces SCom 1 and
SCom 2 on the CU board of the basic units or at the serial interface on
the SCB 2 board by means of the following parameters: P682, P700,
P701, P702, P703 and P704.
The USS protocol is parameterized at the serial interface of the T100
technology board by means of the "technology parameters" H290,
H291, H292, H293, H294 and H295. These parameters are part of the
T100 (see software instruction manual of the T100).
USS protocol at the SCom1 on MASTERDRIVES MC
As already described in Section 8.1.3, the bus cable for the SIMOVERT
MASTERDRIVES MC can be connected either at terminal strip
X100/X103 ("Compact PLUS" type) or at connector X103/X300
("Compact" and "chassis" types).
♦ Settings:
USS protocol with 19.2 kbit/s and 3-word PKW area and 2-word
PZD area
• 3-word PKW area:
With this setting, all parameters whose values are 16-bit
quantities (1 word) can be read and written via the USS protocol.
• 2-word PZD area:
Transfers control word 1 and a setpoint (each of them 16 bit)
from the master to the converter and status word 1 and an actual
value (each of them 16 bit) from the converter to the master.
♦ Preconditions:
P060 = 1 or 7 (default setting)
♦ Parameterizing the SCom 1 interface (applies to X100 or X103
("Compact PLUS" type) and X103 or X300 ("Compact" and
"chassis" types) at the same time):
