Putting EnDat 3 into practice
STOBER has enhanced its One Cable Solution (OCS) so that users can now connect motors and drive controllers at distances of up to 100 using the EnDat 3 protocol from Heidenhain. The new single cable connection means that machine builders no longer need to use two cables to power the motor and transmit encoder data. It can all be done with this one hybrid cable.
Countless lab 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 also eliminates data transmission weakness and removes the need to use an output choke up to 50m. For axes above 50m STOBER supplies a Choke.
STOBERs new OCS is compatible with the STOBER SC6 and SI6 drive controllers, which are suitable for powerful drive systems and highly efficient multi-axis applications. STOBER has also enhanced these two drive controllers with a new series transceiver chip, as used in Heidenhains EnDat 3 encoder, which makes the company the first drive specialist on the market to use the OCS in combination with this encoder solution.
The OCS is designed for use with STOBERs EZ and EZS series synchronous servo motors, which can also be combined with all STOBER gear units in direct attachment, enabling engineers to design much more compact solutions. The results highlight significant customer benefits from maximum data transmission quality, full diagnosis, to safety and performance, which is ideal for digital production and robotics.
The arrival of EnDat 3 is another step along the road to enhanced digital manufacturing which will bring major benefits in the field of data transfer with added reliability and improved performance all round, says Philip Lodge, sales manager at HEIDENHAIN (GB).
