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 )
PZD: Process data

Sets a unique address for the VSD
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 another 30 VSDs via RS-485 (i.e. 31 VSDs in total) and control them with the USS serial bus protocol
P2014[2] USS telegram off time

the USS channels
Unit: ms Min: 0 Def: 0 Max: 65535
Level 3
Index:
