P2009[2] USS normalization
Min: 0 Def: 0 Max: 1
Level 3
Settings:
0=Disabled 1=Enabled
Index:
P2009[0] : Serial interface COM link P2009[1] : Serial interface BOP link
Note:
If 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 ).
P2010[2] USS baudrate
Sets baud rate for USS communication.
Unit: - Min: 4 Def: 6 Max: 12

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

P2011[2] USS address
Sets a unique address for variable speed drive.
Unit: - Min: 0 Def: 0 Max: 31
Level 3
Index:
P2011[0] : Serial interface COM link P2011[1] : Serial interface BOP link
Note:
You can connect up to a further 30 variable speed drives via the serial link (i.e. 31 variable speed drives in total) and
control them with the USS serial bus protocol.
P2014[2] USS telegram off time
Defines a time T_off after which a fault will be generated (F0070) if no telegram is received via
the USS channels.
Unit: ms Min: 0 Def: 0 Max: 65535
Level 3
Index:
P2014[0] : Serial interface COM link P2014[1] : Serial interface BOP link
Note:
By default (time set to 0), no fault is generated (i.e. watchdog disabled).
P2040 CB telegram off time
Defines time after which a fault will be generated (F0070) if no telegram is received via the link (SOL).
Unit: ms Min: 0 Def: 20 Max: 65535
Level 3
Dependency:
Setting 0=watchdog disabled
