Publication 4100-5.3 - June 1999

Overview

The optically isolated encoder input accepts 5 Volt differential

quadrature signals from standard incremental encoders. 5V and 12V

DC are available from the ALEC for powering the encoder. An

optically isolated registration input which latches encoder position is

provided for direct interface to a position registration sensor. This

input can be used directly with 5V or 24 V devices.

AxisLink communication with IMC S Class motion controllers is

controlled by a dedicated communication chip. An address selector

switch is provided on the front panel to set the address of the ALEC

on AxisLink. A front panel AxisLink status LED (AL) is also provided.

The ALEC includes a switching power supply with fused 18-36V DC

input which provides separate outputs for the optically-isolated

encoder input and AxisLink communication channel.
