A wide range of single-axis Line Modules and Motor Modules with graded current/power ratings can be supplied:

• Active Line Modules: Single-axis version
  In chassis format with rated power from 132 kW to 300 kW
• Single Motor Modules: Single-axis version
  In chassis format with rated output currents of 210 A to 490 A

In principle, all Single Motor Modules can operate on Active Line Modules for the corresponding voltage range.

The self-commutated infeed/regenerative feedback units (with IGBTs in rectifier and regenerative directions) generate a regulated DC link voltage. This means that the connected Motor Modules are decoupled from the line voltage. Line voltage fluctuations within the permissible supply tolerances have no effect on the motor voltage.

If required, the Active Line Modules can also provide reactive power compensation.

Active Line Modules are designed for connection to grounded, star (TN, TT) and non-grounded, symmetrical IT supply systems.

In order to operate an Active Line Module, it is absolutely essential to use the appropriate Active Interface Module.
