Siemens SINAMICS G120 Operating Instructions Manual page 479

Function
12 SINAMICS "Standard Drive Control" and "Dynamic Drive Con-
trol" application classes to simplify commissioning and increase
the degree of ruggedness of the closed-loop motor control.
The SINAMICS application classes are available with the fol-
lowing inverters:
SINAMICS G120C
•
SINAMICS G120 with PM240, PM240-2 and PM330 Power
•
Modules
13 Moment of inertia estimator with moment of inertia precontrol to
optimize the speed controller in operation
14 Friction torque characteristic with automatic plotting to optimize
the speed controller
15 Automatic optimization of the technology controller
16 The sign of the system deviation for the additional, free tech-
nology controller 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.
17 The technology controller output can be enabled and disabled
during operation
18 Ramp-function generator remains active with enabled technol-
ogy controller
19 Line contactor control using a digital output of the inverter to
save energy when the motor is switched off
20 Fast flying restart for PM330 Power Modules:
The "Flying restart" function does not have to wait for the motor
demagnetization time, and identifies the motor speed without
requiring a search operation.
21 Load torque monitoring extended to include the following func-
tions:
Protection against blocking, leakage and dry running opera-
•
tion in pump applications
Protection against blocking and broken belts in fan applica-
•
tions
22 Automatic switchover of the real time clock from daylight saving
time (summer time) to standard time (winter time).
23 New or revised default settings of the interfaces: p0015 macros
110, 112 and 120
24 Expansion of the temperature sensors to include DIN-Ni1000
for analog inputs AI 2 and AI 3
Converter with the CU240B-2 and CU240E-2 Control Units
