I/O Terminal /
OVERVIEW
2 OVERVIEW
This section provides an overview of the I/O terminal.
Note:
For information about configuring the I/O terminal, see the Kollmorgen Automation Suite™
IDE software and online help system.
2.1
AKT-ENC-000-000 Incremental Encoder Inputs
The incremental encoder interface terminal enables the connection of any incremental encoders
to the bus coupler or the PLC. A 16-bit counter with a quadrature decoder and a 16-bit latch can
be read, set or activated. Besides the decoder inputs A, B, C, an additional latch input G1 (24 V)
and a gate input G2 (24 V) for disabling the counter are available.
The 16-bit up / down counter mode can also be selected. In this mode of operation, input B is the
counting input.
1-fold, 2-fold or 4-fold evaluation of the encoder signals A, B, C in simple or complementary form
can be parameterized via the field bus.
The terminal is supplied as a 4-fold quadrature decoder with complementary evaluation of the
encoder signals A, B, C. For operation of the encoder interface, the operating voltage of 24 V DC
must be connected to the terminal contacts in addition to the encoder inputs.
Additional features include:
The incremental encoder with fault alarm outputs can be connected to the Status input of the
AKT-ENC-000-000.
A period measurement with a resolution of 200 ns can also be performed.
