Function
11 SINAMICS "Standard Drive Control" and "Dynamic Drive Control" applica-
tion classes to simplify commissioning and increase the degree of rug-
gedness of the closed-loop motor control.
The SINAMICS application classes are available with the following invert-
ers:
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 con-
troller 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
operation
17 Ramp-function generator remains active with enabled technology control-
ler
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 demag-
netization time, and identifies the motor speed without requiring a search
operation.
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
(summer time) to standard time (winter time).
22 New or revised default settings of the interfaces: p0015 macros 110, 112
and 120
