Options

Option G33 (Communication Board CBE20)

The interface module Communication Board CBE20 connects SINAMICS drives to the PROFINET. The CBE20
board allows to use PROFINET IO with IRT support and PROFINET IO with RT support. Mixed operation is not
possible. PROFINET CBA is not supported. When a CBE20 board is used the SINAMICS S120 drive becomes an IO
device.
The interface module Communication Board CBE20 is mounted in the option slot of the Control Unit CU320.
Therefore it can be ordered as option G33 only in combination with Option K90/ K91 (Control Unit CU320).

Option K75 (Second auxiliary busbar)

If the application requires more supply voltages than can be provided by the auxiliary busbar system integrated in the
basic model, additional auxiliary voltages for the Cabinet Modules can be obtained by installing the second auxiliary
busbar option. The optional busbar system provides an additional six cable railway (divided into three times two
levels).
The option is supplied as standard with three 2-pin connectors for each Cabinet Module which are designed to
facilitate interconnection of individual Cabinet Modules.
Fitting of the optional auxiliary busbar system
The 6-pole busbars have the same properties as the standard bar.
Connectors for voltage pick-off and Infeed can be ordered by using the order number 5ST2545.

Option K82 (Terminal module for controlling the "Safe Torque Off" and "Safe Stop1" functions)

Before protection devices can be opened the saftey functions „Safe Torque Off" or „Safe Stop1" must be activated.
The Safe Torque Off function prevents unexpected rotation of the connected motor at standstill. Before the Safe
Stop1 function decelerates the motor in accordance to the deceleration ramp. These two safety functions are
included as standard with S120 Cabinet Modules.
