Bus termination on USS variant
The USS variant of the SINAMICS G110 inverter uses RS485 protocols to
communicate with the controlling system and all other inverters connected to the
network.
It is necessary to terminate the last inverter on the network bus. This is achieved by
setting the Bus Termination DIP switches on the front of the inverter to the 'Bus
Termination' position (as shown in Figure 3-2 on page 34). It is important that both
DIP switches (2 and 3) are set to the 'Bus Termination' position (not in the OFF
position). A small screwdriver will be required to change the position of the DIP
switches.
3.3.2 Commissioning with the Optional Basic Operator Panel
If the optional 'Basic Operator Panel' (BOP) is available, the control signals and
speed reference can easily be set by pressing the relevant buttons. The BOP also
provides easy access to the inverter parameters. This section describes how to
commission and start the inverter with the minimum of effort, using the BOP.
For advanced use of the BOP to perform for example, the full inverter
commissioning see Section 3.4.1 on page 42 or refer to Section 3.4.7 on page 49
for information about parameter cloning using the BOP.
For instructions on how to fit the BOP to the inverter, please refer to Appendix C on
page 82 and for a description of the buttons see Appendix D on page 83.
The BOP must be connected directly to the
inverter and not remotely connected via a
cable.
The BOP can be fitted to and removed from
the inverter whilst power is applied.
The inverter will automatically recognize that
the BOP has been fitted to the inverter and
give the user access to the parameters. To
run the inverter (start/stop, setpoint) using
the BOP, parameters P0700 (command
source, i.e. start/stop, reverse, jog) and
P1000 (frequency setpoint) have to be set to
1. Alternatively, P0719 can be set to 11
which is described below.
Note
The motor base frequency might have to be changed as described in the previous
section on page 34.
