21 January 2009
– The single speed drive  

Danfoss’ new VLT® MCD 500 Soft Starter is a complete motor starting solution with advanced start, stop and protection features, Adaptive Acceleration Control (AAC), built-in delta connections, a four-line graphical display and multiple programming setup menus.
The VLT® MCD 500 is an advanced intelligent motor starting solution that constantly monitors the behaviour of its load to adjust and refine its dynamic performance.

The AAC principle automatically selects and adjusts the best starting and stopping profile for the application. It measures motor current and provides feedback for constant improvement of the motor ramp profiles.  

The MCD 500 offers a four-line graphical display and a logic keypad making programming easy. A more advanced setup is also possible, displaying full operational status. The MCD 500 has three menu systems providing the optimum programming approach: 

             -       Quick Menu, 
             -       Application Setup      
             -       Main Menu

The MCD 500 covers the range 21 – 1600 A. (7.5 – 800 kW), and offers versions for the whole voltage range 200 – 690 VAC.  The power range can be extended to 1.2 MW when using the inside delta connection.

VLT® MCD 500 Soft Starter has a series of options for serial communication:
            –          DeviceNet 
            –          Profibus
