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.

I/O Terminal / OVERVIEW

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.

2.1.2 Assignments of Terminal Contact

I/O Terminal / OVERVIEW

Inputs A, /A

Pulse input in the terminal’s encoder and counter mode.

Inputs B, /B

Phase-shifted pulse input in the terminal’s encoder mode.
Counting direction input in the terminal’s counter mode.

Counting direction:

 + 5 V (or open contact): up
 0 V: down

Inputs C, /C

Zero point pulse input for the terminal’s latch register.
This input is activated via the EN_LATC bit in the terminal’s control byte.

External Latch 24 V

Additional latch input of the terminal.
The counter value is latched when this input is alerted and an edge change takes place from 0 V
to 24 V.

External Gate 24 V
