SINAMICS S120 drive system
0.12 kW to 250 kW (0.16 hp to 400 hp)
SINAMICS S120 drive system
■
Overview
Thanks to its modular design, the SINAMICS S120 drive system
can be perfectly adapted to a wide range of different drive tasks
utilizing induction, servo, linear, and torque motors. The
SINAMICS S120 modular components are computed on the
Control Unit. Power units (Power Modules, Line Modules and
Motor Modules) ensure an optimum conversion of energy be-
tween the supply system and motor. SINAMICS S120 inverters
are available in blocksize, booksize, booksize compact and
chassis formats or as distributed inverters (SINAMICS S120M).
SINAMICS S120 offers optimum solutions for simple, single-axis
drives as well as for complex multi-axis drives.
SINAMICS S120 inverters can be used for many different
applications.
Typical application examples are:
•
Turning, milling and grinding machines
•
Packaging machines
•
Machines for producing food and beverages
•
Printing and paper machines
•
Textile machines
•
Plastics processing machines
•
Presses and punches
•
Machines used in the wood, glass, and ceramics industries
•
Assembly and testing equipment
•
Handling equipment
•
Rolling mill drives
•
Vehicle and gearbox test stands
•
Hoisting gear, cranes
•
Plants and processing lines
•
Test bays
•
Renewable energy
SINAMICS S120 single-axis drives (AC/AC)
SINAMICS S120, PM240-2 FSC, CU310-2 PN
The simplest version of a SINAMICS S120 is a single-axis drive.
It consists of a CU310-2 Control Unit and a Power Module. A
mains rectifier, a voltage-source DC link and an inverter for
supplying the motor are integrated in the Power Module.
SINAMICS S120 Power Modules are single drives which are not
capable of regenerating energy to the supply. Generated energy
produced during braking can be converted to heat via braking
resistors. Power Modules for SINAMICS S120 are available in
the following formats and power ranges:
SINAMICS S120 single-axis drives essentially offer the following
additional functions compared to SINAMICS S110:
•
Higher power up to 250 kW (400 hp)
•
Operation of linear and torque motors
•
Motor and machine encoders can be evaluated
simultaneously
•
Flexible technology functionality with Drive Control Chart
(DCC)
•
Higher dynamic response for current, speed and position
control loop
•
Vector control for highly precise torque control of
asynchronous (induction) motors
•
More digital I/Os via external terminal modules
•
Integrated web server (firmware version V4.6 and higher)
