• Integrated webserver

• Recessed hollow shaft

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 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-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.
