Overview
Flexibility for successful machine concepts
As part of the SINAMICS drive family, the SINAMICS S120 drive
is a modular system for high-performance applications in ma-
chine and plant engineering. SINAMICS S120 offers high-perfor-
mance single-axis and multi-axis drives for a very broad range
of industrial applications. By virtue of its scalability and flexibility,
SINAMICS S120 is the ideal system for satisfying the ever
对更多轴的需求增加和更好的性能。
SINAMICS S120 supports flexible machine designs and speedy
implementation of customized drive solutions.
The response to ever increasing demands
现代机器必须以较低的成本建造，而是提供
ever greater productivity. The SINAMICS S120 drive concept
meets both these challenges! It is easy to configure and thus
helps to reduce project completion times. Its excellent dynamic
response and accuracy permit higher cycle rates for maximum
productivity.
Applications in machine and plant engineering
无论应用程序是否涉及连续
material webs or cyclic, highly dynamic processes –
SINAMICS S120 means increased machine performance in
many industries:
•
Packaging machines
•
Plastics processing machines
•
Textile machines
•
Printing machines
•
Paper machines
•
木工机器
•
Hoists and cranes
•
Handling and assembly systems

Machinery associated with renewable energy applications
机械工程的模块化
SINAMICS S120 is designed to allow free combination of power
and control performance. Multi-axis drives with higher-level
运动控制可以用SINAMICS S120实现
模块化系统s easily as single-drive solutions.
Greater flexibility with central control intelligence
On the SINAMICS S120, the drive intelligence is combined with
闭环控制功能进入控制单元。
These units are capable of controlling drives in Vector, Servo and
V/f
modes. They also perform the speed and torque control
功能plus other intelligent drive functions for all axes on the
drive.
Free performance selection for Vector and Servo control modes
The use of a SINAMICS S120 Vector control is recommended for
drive solutions with continuous material webs, for example, wire-
drawing machines, film and paper machines, as well as for
hoisting gear, centrifuges and marine drives with harmonic,
circular motion.
Servo control with SINAMICS S120 is employed for cyclic pro-
cesses with precise, highly dynamic position control and servo
motors, e.g. in textile, packaging, printing machines and
machine tools.
SINAMICS S120 – functions for better efficiency
•
Basic functions: Speed control, torque control, positioning
功能
•
Intelligent starting functions for independent restart after
power supply interruption
•
BICO technology with interconnection of drive-related I/Os for
easy adaptation of the drive system to its operating
environment
•
Integrated safety functions for rational implementation of
safety concepts
•
Regulated infeed/regenerative feedback functions for
preventing undesirable reactions on the supply, allowing
recovery of braking energy and ensuring greater stability
against line fluctuations.
