Single cable transmits data and power up to 100 metres

Designed in collaboration with encoder experts Heidenhain, STOBER says that its new, single cable connection means that machine builders no longer need to use two cables, one to power the motor and the other to transmit encoder data because both can now be done with its new single cable.

The company confirms that laboratory tests over continuous operation have revealed that the quality of the data transmission enabled all signals to be read and evaluated “flawlessly without errors in the encoder communication, even after five million cycles”. The new OCS is also said to eliminate data transmission weakness and remove the need to use an output choke up to 50m. For axes above 50m STOBER supplies a choke.

Single Cable Connection of Motors and Controllers

STOBER’s new OCS is compatible with the company’s SC6 and SI6 drive controllers, which are suitable for powerful drive systems and efficient multi-axis applications. STOBER confirms that it has also enhanced these two drive controllers with a new series transceiver chip, as used in Heidenhain’s EnDat® 3 encoder, which it claims makes the company the first drive specialist to use the OCS in combination with this encoder solution. 

The OCS is designed for use with STOBER’s EZ and EZS series synchronous servo motors, which can also be combined with all of the manufacturers gear units in direct attachment, enabling engineers to design more compact solutions. As a result, the company points out that customers benefit from maximum data transmission quality together with the full diagnosis, safety and performance required for digital production and robotics.
