Parker Hannifin Corporation, the global leader in motion and control technologies, has released its new Single Cable Servo Drive System, consisting of servo motors from the successful SME series and TPD-M triple-axis servo drive, which together provide OEM’s with a significant reduction in overall drive system complexity. Unlike conventional solutions which require separate motor power and encoder feedback cables between servo motor and drive, this new and innovative solution only requires one single cable connection.
The SME series of single cable option servo motors uses a new and innovative protocol HIPERFACE DSL®, a completely digital and interference-free absolute position feedback system for servo motors and drives. This integrates the encoder communication into the motor power connection cable – completely eliminating the need for a separate feedback connection cable between drive and motor. The resolution of this high performance encoder is 18 bits per turn, as well as 4,096 maximum rotations. SME servo motors are available in flange sizes from 60 mm to 142 mm, a nominal torque range from 0.35 to 17 Nm and nominal speeds up to 7500 rpm. Due to their extremely low rotor inertia, SME motors are especially suitable for highest dynamic requirements frequently found in food processing and packaging machines, material forming machines and general factory automation applications.
When combined together with Parker’s TPD-M series of servo drives they make a unique solution which reduces not only cabling cost and machine installation time for machine builders, but also enables engineers to design products with a smaller footprint and simplified mechanical elements.
TPD-M is the world’s first multi-axis servo drive family which can control up to three servo motors with one single 50 mm axis module – making it the most compact multi-axis servo drive available on the market and an ideal solution for machine builders to reduce control cabinet size. The use of a central power supply and common coupling of all drives via a shared DC bus permits energy efficient sizing since decelerating motors can transfer their energy directly to the drives in motoring mode.
