Table 3-2 Factory Settings For Operation Using The Standard Inverter (Uss Variant) - Siemens SINAMICS G110 Operating Instructions Manual

Commissioning
Controlling the speed of the motor is accomplished on the Analog variant by
connecting a potentiometer (≥ 4.7 kΩ) to the analog input (external switches and
potentiometers are not supplied with the inverter) or via the RS485 connections on
the USS variant as shown in the Figure 3-3 above.

Controlling the speed of the motor on the USS variant is accomplished by
connecting the RS485 connections as shown in Figure 3-3 on page 35.
(USS master or software tool are not supplied with the inverter).
When controlling a USS variant inverter the process data is continually exchanged
between the master and the slaves.
The PZD part of the USS telegram is used for the main setpoint and for controlling
the inverter.
Depending on the direction of communications (PZD from USS Interface or PZD to
USS Interface) PZD transmits either a control word (STW) and setpoint (HSW) or a
status word (ZSW) and an actual value (HIW).
STW (Control Word)
ZSW (Status Word)
Warnings and faults states on the inverter
The LED indicates the operating status of the inverter. The LED also indicate
various warnings or fault states. In section 6.1 on page 65, the inverter states
indicated by the LED are explained.
