Outgoing Motor Cable Connections The outgoing motor cables connect to a cable stand-off assembly on the cabinet side sheet (Fixed-mounted Power Module configuration) or to the cable standoffs mounted on the Isolation Transformer (Drawout Power Module configuration). The outgoing motor cables connect to output phase of the power module array. Outgoing motor cables can be brought in through the top or bottom of the isolation transformer cabinet. Generous working space is provided. See publication 6000-IN006_-EN-P for additional details.
Power Modules Power Modules are available in a wide variety of amperage ratings relating to the required motor current. Power Modules rated up to and including 200 A are fixed-mounted in the drive and ship already installed. Drawout power modules are supplied for a drive current rating of >200 A. The power modules are shipped separately and must be installed in the cabinet. A Power Module lift cart is included and shipped together with the other components. Basic Principle of Power Module The Power Module combines a three phase rectifier and an “H” bridge inverter, powered from the secondary side windings of the Isolation Transformer. After rectifying and filtering, it outputs AC current with variable frequency and variable voltage under the control of four IGBTs using a PWM switching pattern. Several Power Modules, after being connected in series and superposed, can output three-phase AC current with adjustable frequency and voltage to control an AC motor
