Description

In addition to the CANopen-, DeviceNet-, PRO-

FIBUS- and AS-Interface encoders, we have

broadened our product line of bus-capable ab-

solute encoders with the ESM58 for Ethernet.

Absolute singleturn rotary encoders deliver an

absolute step value for each angle setting. This

device has a maximum basic resolution of

65536 steps per revolution (16 bits).

The Ethernet interface of this absolute encoder

supports the Profinet 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-ser-

vices, change of the IP address and many

others, the following operation modes can be

selected:

•

Polled Mode

•

Cyclic Mode

•

Change of State Mode

The device is mounted directly onto the applica-

tion shaft, without any coupling. Rotation of the

absolute encoder is prevented by a torque rest.
