Cold plate version of servo drive announced

10 April 2012

A compact, cold plate version of the DIAS Drive SDD 310 is now available from Sigmatek. The three-axis servo drive system can be operated with 3 x 10 A continuous and 3 x 20 A peak current and is therefore optimally suited for multi-axis applications in a power range up to 14 kW.

Through an aluminum plate, mounted on the back of the drive, the generated heat loss for the cold-plate version of the drive is dissipated directly into the chosen cooling medium used in the application. The drive can, therefore, be flexibly and inexpensively integrated into the cooling concept of the machine.

The minimal cycle time of the controller is said to provide the DIAS Drive 310 with excellent servo performance. The functions are intentionally limited to current, rotation and position control with integrated spline interpolation to avoid unnecessary expenditure. The DIAS Drive 310 has an individually adjustable and scaleable output stage concept for servo motors.

With the SDD 310 servo, linear, torque and asynchronous motors can be controlled. All conventional feedback systems (Resolver, Hiperface, EnDat and high-resolution Sin/Cos encoders) can be used. Safety functions (SIL 3, PL e) such as ‘Safe Torque Off’ (STO) and ‘Safe Stop’ (SS1), which are already integrated, simplify the integration of the drive technology into the machine's Safety concept.
