Siemens SINAMICS G120C USS/MB Operating Instructions Manual page 433

Function
12 Moment of inertia estimator with moment of inertia precontrol to optimize
the speed controller in operation
13 Friction torque characteristic with automatic plotting to optimize the speed
controller
14 Automatic optimization of the technology controller
15 The sign of the system deviation for the additional, free technology control‐
ler can be switched over.
A new parameter defines the sign of the system deviation matching the
particular application, e.g. for cooling or heating applications.
16 The technology controller output can be enabled and disabled during op‐
eration
17 Ramp-function generator remains active with enabled technology controller
18 Line contactor control using a digital output of the inverter to save energy
when the motor is switched off
19 Fast flying restart for PM330 Power Modules:
The "Flying restart" function does not have to wait for the motor demagnet‐
ization time, and identifies the motor speed without requiring a search op‐
eration.
20 Load torque monitoring extended to include the following functions:
● Protection against blocking, leakage and dry running operation in pump
applications
● Protection against blocking and broken belts in fan applications
21 Automatic switchover of the real time clock from daylight saving time (sum‐
mer time) to standard time (winter time).
22 New or revised default settings of the interfaces: p0015 macros 110, 112
and 120
23 Expansion of the temperature sensors to include DIN-Ni1000 for analog
inputs AI 2 and AI 3
24 Communication via AS-Interface.
Default setting of the communication via AS-i: p0015 macros 30, 31, 32
and 34
25 Communication expansion via Modbus:
Adjustable parity bit, access to parameters and analog inputs
26 Extending communication via BACnet:
Access to parameters and analog inputs
27 The bus error LED for communication via USS and Modbus can be switch‐
ed off
