Control Techniques has extended the power range of Commander SK AC drives up to 132 kW. The company believes that never before has so much power and versatility been packed into such a small space. Commander SK requires up to half the foot print space and volume compared with other drives of the same power rating.
The range has been designed to meet the needs of the majority of drives users covering 0.25 to 132 kW. They are easy-to-fit, set up and use, while connectivity to all major fieldbus networks enable integration with other automation equipment. Ethernet/internet communications allow global drive access.
Installation is straightforward, with a choice of DIN-rail or simple panel mounting and clearly marked terminals make connecting the drive very easy. The most commonly used parameters are detailed on the front of the drive to simplify the configuration to get the drive up and running within moments.
Size is frequently a key issue both with OEMs and end users. Compact drives allow designers to reduce the cubicle space required resulting in more compact machines for OEM’s and allowing greater potential for retrofit applications for end users such as in energy saving applications.
“This increase in the power to size ratio has been achieved by a radical rethink of drive design,” explains product manager, Enrique Viseras, “and much of this is down to the use of composite materials used in its enclosure. This puts the Commander SK right in the forefront of drive technology delivering huge user benefits.”
Commander SK offers automatic, no-spin autotune for optimal performance, open loop vector control, speed or torque control and adjustable switching frequency for quiet motor operation. What’s more, it has PID control, both linear and S-type acceleration and deceleration ramps, DC injection braking and onboard EMC filter and gives excellent energy savings with dynamic motor flux control.
The list of options includes: remote keypads, SmartStick for cloning drive parameters, LogicStick for memory storage for PLC programmes, serial cable for PC connection and a suite of free PC software tools, for advanced drive programming. And that’s not all, Commander SK is an economical drive with PLC functionality, giving the option to replace a nano or micro PLC, or to replace relays and timers.
