An inverter control cabinet integrates a variable frequency drive with the switching, protection, metering and control devices required by a motor application. The enclosed cabinet can place the drive keypad and operating controls on the front door for local access.
Configuration options
Main circuit breaker, drive start/stop controls and a front-panel frequency or speed setting.
Voltmeter, ammeter, frequency meter and indicators for power, alarm, running state, input voltage, output current and output frequency.
Optional input, output or DC reactors, EMI filter, braking unit and resistor, contactors, relays, thermal protection, PLC, HMI, energy meter and cooling fans.
Local, remote, PC or PLC control, with optional fixed-frequency bypass arrangements for continuity of operation.
Ordering information
The built-in drive rating, enclosure, controls and accessories depend on the motor, load, supply, operating sequence and required interfaces. Provide the application wiring diagram and functional requirements before configuration.
