Product Details Supplier Info More products

CMC has selected compact Digitax ST servo drives and brushless servomotors from Control Techniques to enhance the throughput, efficiency and performance of its automated handling machines.

CMC is a manufacturer of automated handling machines for the cookware, ceramic and tableware industries.

Following an assessment of the machinery, Control Techniques recommended brushless servomotors for high-precision positioning and lower energy loss, with drives fitted with Sin/Cos absolute encoders to memorise and store axis positions.

Key information

  • The servo drives and brushless servomotors from Control Techniques have enhanced the handling, efficiency, performance and throughput of CMC’s automated handling machines.
  • In this application, the Digitax ST servo drives are used with centralised motion controllers and can be connected using digital or analogue networks.
  • Optional plug-in modules interface the servo drives with dedicated servo networks (Ethercat, Sercos or CANopen).
  • Dedicated I/Os include a high-speed ‘freeze’ input, a high-resolution analogue input and a simulated encoder output.
  • The encoder input accepts feedback signals, Sin/Cos, Hiperface, Endat and SSI.
  • The Digitax ST range features four models and four product variants — Base, Indexer, EZ Motion and Digitax ST Plus — optimised for servo applications requiring high peak torque, excellent dynamic response, faster installation and start-ups and ease of integration.
  • Digitax ST has a ‘safe torque off’ standard input that disables the power stage of the drive for maintenance purposes.
