● Line-side power components such as fuses and contactors to switch the energy supply
● Reactors and filters to maintain EMC regulations
● Motor Modules for 1 - 2 expansion axes which function as inverters and provide th
e
ener
gy to the connected motors
● DC link components (Braking Module, Control Supply Module) used optionally for
stabilizing the DC link voltage
● Additional system components and encoder system connections to expand t
he
f
unctionality and to handle various interfaces for encoders and process signals.

as a result of the following properties: 
● Easy to handle, simple installation and wiring
● Practical connection system, cable routing in accordance with EMC requirements
● Standardized design, side-by-side mounting
Application and cooling method 
The S120 Combi Power Modules are optimized as a drive for processing machines with 3 to 
6 axes. The Power Modules are available with the "external air cooling" cooling method. 
Motor Modules in the booksize compact format are used as expansion axes.
