6 General Information about Built-in and Cabinet Units SINAMICS S120

6.1 General

Information about the components of the SINAMICS S120 modular drive system can be found in the following
chapter. It is important to refer to this information when configuring a drive system in order to ensure compatibility and
satisfactory inter-operation between individual drive components.
For information about individual components, please also refer to the online help of the "SIZER for Siemens Drives"
configuring tool.

Performance features of the CU320-2 Control Unit

The performance features of the CU320-2 Control Unit are described below. This Control Unit is used on all devices
of the SINAMICS S120 modular drive system described in this engineering manual.
The CU320-2 Control Unit uses an object-oriented standard firmware for the devices of the SINAMICS S120 modular
drive system. This firmware supports all common types of open-loop and closed-loop control modes, ranging from
simple V/f control to universal vector control and highly dynamic servo control.
The following control modes are available as configurable drive objects:
·
Infeed Control, the closed-loop control for the Active Infeed
·
Vector Control, the universal standard closed-loop control for asynchronous and synchronous motor drives
·
Servo Control, the closed-loop control for highly dynamic drives
All common types of V/f control modes are available in the vector-type drive object and are used for uncomplicated
drives in the power range up to a few 100 kW, and for group drives (multiple motors connected to one Motor Module).
The control modes Vector Control (vector-type drive objects) and Servo Control (servo-type drive objects) are based
on the principle of field-oriented closed-loop control.
