Function: ESS58-TZ

In addition to the CANopen-, DeviceNet-, PROFIBUS- and AS-Interface encoders, we have broadened our product line of bus-capable absolute encoders with the ESS58 for Ethernet.

Absolute rotary encoders deliver an absolute step value for each angle setting.

The absolute encoder has a maximum basic resolution of 65536 steps per revolution (16 Bits).

The Ethernet interface of this absolute encoder supports the TCP/IP protocol. The integrated webserver provides Java applets, which allow the whole parameterisation of the encoder via any web browser. In addition to various functions like resolution adjustment, e -mail-services, change of the IP address and many others, the following operation modes can be selected:

  • Polled mode

  • Cyclic mode

  • Change of state mode

The absolute encoder is mounted directly onto the application shaft, without any coupling. Rotation of the absolute encoder is prevented by a torque rest.
