The incremental encoder input can be
used for the exact regualtion of speed
of rotation, additional set point
functions or positioning.
An encoder system with 10-30V supply
voltage must be used in order to
compensate for voltage drop in long
cable connections.
Note:
Encoders with 5V supply are not
suitable in order to set up a system
which operates reliably.
