Description

The drive line-up is connected to the power supply network via the Power Modules.
A Power Module is a power unit (frequency inverter) that provides the power supply for the
connected motor. The power from the 3-phase system is supplied via the 6-pulse rectifier.
The output inverter produces a 3-phase, variable-voltage, variable-frequency system. A
Power Module must be connected to a Control Unit via DRIVE-CLiQ. The open-loop and
closed-loop control functions are stored in the Control Unit.
