3.3 Precharging intervals of the DC link

3.3.1

SINAMICS Booksize units

The precharging intervals of the DC-link for Line Modules in Booksize format can be calculated using the following
formula
No. of prechargin g operations
3.3.2

SINAMICS Chassis units

For Line Modules in Chassis format, the maximum permissible DC link precharging interval is 3 minutes. This limit of
3 minutes applies generally to all other SINAMICS G and SINAMICS S Chassis and cabinet units. (Exception: S120
Basic Line Modules in frame sizes FB/FBL and GB/GBL which are equipped with thyristors. In this case, no
precharging intervals apply due to the precharging principle based on phase angle control).
The currents associated with the precharging procedure of the DC link are specific to the unit types and can therefore
be found in the chapters relating to specific unit types in this document.

3.4 Operator Panels

The SINAMICS range includes two operator panels for units in the G130 and G150 range, as well as for S120
(Booksize, Chassis, Cabinet Modules) and S150. The Basic Operator Panel BOP20 is designed to meet simpler
requirements, while the Advanced Operator Panel AOP30 offers a wider scope of functions.
3.4.1

Basic Operator Panel (BOP20)

The optional Basic Operator Panel BOP20 which can be plugged into the CU320-2 Control Unit can be used to
acknowledge faults, set parameters and read diagnostic information (e.g. warnings and error messages).
The Basic Operator Panel BOP20 has a backlit two-line display area and 6 keys.
Basic Operator Panel BOP20
The integrated plug connector at the rear of the Basic Operator Panel BOP20 supplies its power and enables
communication with the CU320-2 Control Unit. The panel cannot and must not be installed remotely from the
CU320-2 Control Unit and connected via a cable.
3.4.2

Advanced Operator Panel (AOP30)

The Advanced Operator Panel AOP30 is a user-friendly input/output device. It is equipped with a membrane
keyboard offering numerous functions and a multi-line graphic display with which a broad range of help functions can
be accessed. In contrast to the BOP20, this panel offers commissioning and diagnostic capabilities in addition to the
functions required in normal operation.
