SINAMICS "Standard Drive Control" and "Dynamic Drive Control" applica‐
tion classes to simplify commissioning and increase the degree of rugged‐
ness of the closed-loop motor control.
The SINAMICS application classes are available with the following inver‐
ters:
● SINAMICS G120C
● SINAMICS G120 with PM240, PM240-2 and PM330 Power Modules
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
Converter with the CU250S-2 Control Units
