This module is an interface for any incremental encoder with an RS-422
connection.
A counter with quadrature decoder as well as a latch for the zero impulse can
be read or enabled by the control. The control can set the counter or transmit
the counter value to the Latch. As an alternative this can also be done using
input “C” or “Latch”.
The frequency data is automatically acquired and can also be transmitted to
the control.
A counter lock-out is possible using input G. Input “Ref“ can be used to activate
the initial point “C“ function.
The cam outputs N1 and N2 indicate whether the counter value is within a
defined range of values. The range can be adjusted.
The module must be powered using an external 24VDC power supply, from
which power to the transmitter (Ue, U1) can also be derived.
The shield (screen) is directly connected to the DIN rail.
