Single-cable system for servo drive reduces hardware requirements
- February 11, 2014
- Product Release
- Automation and Robotics
All motors normally need two separate cables: one for the motor speed encoder and the other for the motor power supply. With HMC 6, the Hybrid Motor Cable Project, Heidenhain has integrated the encoder lines into the power cable so only one cable is needed between a synchronous motor and electrical cabinet. All the lines for the encoders, motors, and brakes are available in one cable, reducing hardware and associated costs.
For connection to the inverter, the cable is split into power connections and an encoder connector. This makes it compatible on the control side with all the same components as conventional cables.
The single-cable system is designed for the company’s encoders with EnDat 2.2 interface with purely serial transmission; however, all other encoders with purely serial RS-485 interface also can be connected.
