Superior soft start performance for fixed-speed applications
The VLT® Soft Starter MCD 600 combines the latest in advanced controls and protections with an increased level of intelligence for superior performance in fixed-speed applications.
The MCD 600 is more flexible than ever to install, thanks to a wide variety of Ethernet and serial-based communication option cards, application-dedicated smart cards and support for eight languages.
An integrated bypass ensures both extremely high efficiency and harmonic-free operation at full speed, reducing energy consumed and required cooling capacity. Ease of use is in focus with features such as the pump-clean function, PowerThrough operation, and calendar or run time-based scheduling. More extensive motor and starter protections ensure more uptime.

Features and benefits
Inbuilt impeller cleaning assistance with Pump clean functionality
Easy application analysis with up to 348 events logged, as well as QR code scan for serial number and event data
Easy data access and reduced startup and upgrade time thanks to integrated USB port
More reliability, more uptime with expanded motor and controller protections
Flexibility for low speed applications, with Jog function
Improved uptime with PowerThrough function which uses 2-phase control if one phase is damaged by shorted SCR
Easy connectivity for the soft starter to Ethernet-based networks, such as PROFINET and EtherNet/IP
Programming is quick and easy thanks to three menu systems (Quick Menu, Application Setup and Main Menu), a four-line graphical display and a logic keypad
The best starting and stopping profile for the application is chosen using Adaptive Acceleration Control (AAC)
Installation costs are lower and there is less stress on the motor thanks to DC injection braking distributed evenly over three phases
Save space and reduce installation costs, thanks to the internal bypass contactors

Drives for compressors in residential buildings
Variable speed control of a chiller allows you to provide constant pressure regulation while matching the capacity to the actual need based on measurements in the system. Speed control is beneficial when a compressor runs for long periods at partial load. Reduce operational costs by running applications at a lower speed which reduces energy consumption. And reduce installation costs by optimizing the system and the compressor itself.
