Description

In addition to the CANopen-, DeviceNet-, PRO­FIBUS- and AS-Interface encoders, we have
broadened our product line of bus-capable ab­solute encoders with the ESM58 for Ethernet.
Absolute multiturn 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) and codes
up to 16384 revolutions (14 bits). Thus the over­all resolution amounts to 30 bits. On account of
the high number of measuring steps resulting
(more than 1 billion), this type of encoder can be
used to divide very long linear distances into
small measuring steps.
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-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 device is mounted directly onto the applica­tion shaft, without any coupling. Rotation of the
absolute encoder is prevented by a torque rest.
