9.6 Process interfaces
9.6.1 Encoder interface
The encoder interface option E2 (E4)
41
enables the connection of an external
incremental encoder (such as: Litton encoder G71SSLDBI-4096-151-05BX). Use
this to synchronize COMPAX with an external speed using the "SPEED SYNC"
command. The encoder pulses per revolution and the translational travel per
encoder revolution are set via the COMPAX parameters P143 and P98.

Does not apply for COMPAX 1000SL. COMPAX 1000SL allows to configure the
generally available signal interface either as encoder input or as encoder emulation (See
page 61).
