Communication parameters (USS, CB)

P2009[2]

USS denormalization

CStat: CT
P-Group: COMM
Enables denormalization for USS.
Possible Settings:
0 Disabled
1 Enabled
Index:
P2009[0] : Serial interface COM link
P2009[1] : Serial interface BOP link
Note:
If denormalization is enabled, the main setpoint (word 2 in PZD) is not interpreted as 100 % = 4000H, but as
"absolute" instead (e.g. 4000H = 16384 means 163.84 Hz ) if this is a frequency. Denormalization (P2009 =
1) only works for frequencies and is intended for backwards compatibility with MM3.
P2010[2]

USS baudrate

CStat: CUT
P-Group: COMM
Sets baud rate for USS communication.
Possible Settings:
4 2400 baud
5 4800 baud
6 9600 baud
7 19200 baud
8 38400 baud
9 57600 baud
10 76800 baud
11 93750 baud
12 115200 baud
Index:
P2010[0] : Serial interface COM link
P2010[1] : Serial interface BOP link
P2011[2]

USS address

CStat: CUT
P-Group: COMM
Sets unique address for inverter.
Index:
P2011[0] : Serial interface COM link
P2011[1] : Serial interface BOP link
Note:
You can connect up to a further 30 inverters via the serial link (i.e. 31 inverters in total) and control them
with the USS serial bus protocol.
