Issued: 02/2008 Frequency Converter SINAMICS G120 on PROFIBUS DP and PROFINET
Preface Notes Startup with PROFIBUS Startup with PROFINET Program Example
Optional Additional Components
Numerous supplementary components are available for the SINAMICS G120, such as:
• Basic Operator Panel (BOP)
With the Basic Operator Panel BOP -that can be inserted in the control unit- drives can be started
up, current operations can be monitored, and individual parameters can be set. In addition, the BOP
provides a function for copying parameters in a time-saving way.
• PC Converter – Connecting Set (PC Connection Kit)
This kit is used for controlling and starting up a converter directly from the PC, provided the
corresponding software (STARTER) is installed. The startup tool STARTER on CD ROM is included
in the PC Converter Connection Set.
• Brake Relay
With the brake relay, you can set up a connection between the power module and an electro-
mechanical motor brake. Thus, the motor brake can be controlled directly with the control unit.
• Safe Brake Relay
With the safe brake relay, you can establish a connection between the power module and an
electrical-mechanical motor brake. Thus, safe brake controls can be implemented directly with the
control unit according to EN 954-1 Safety Category 3 and IEC 61508 SIL 2.
• MicroMemoryCard (MMC)
On the MMC, you can store the parameter assignment of the converter. If servicing is required, the
plant is immediately ready after the converter is replaced and the data is copied back from the
memory card. The associated slot is located on top of the control unit.
• Line-Side Power Components
• Network Filters Class A and B
With an additional network filter, the Power Module PM240 attains a higher radio interference
class.
• Line Reactors
A line reactor is needed if the system fault level is high, for two reasons: on the one hand, to
protect the converter itself from harmonic currents and overloads, on the other hand to limit
system perturbation to the permissible values.
