Description

The motor modules are connected to the power supply network via the active line
moduleswhich provide the motor modules with a constant DC link voltage. This ensures that
they are not influenced by network fluctuations. The regenerative feedback capability of the
modules can be deactivated by parameterization.
The active line modules are suitable for direct operation on TN, IT, and TT systems.
When the motors are in feedback mode, active line modules supply power back to the
network.
The ratio of line short-circuit power to rated power must be ≥ 70.
