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.

I/O Terminal / MOUNTING AND WIRING

3 MOUNTING AND WIRING

This section provides mounting and wiring information for the operator terminal.
Note: For information about configuring the I/O terminal, see the Kollmorgen Automation Suite™

IDE software and online help system.

3.1 Installation of Bus Terminals on Mounting Rails

DANGER!! Bring the bus terminal system into a safe, powered down state before starting

installation, disassembly or wiring of the Bus Terminals!

3.1.1 Assembly

The Bus Coupler and Bus Terminals are attached to commercially available 35 mm mounting
rails (DIN rails according to EN 50022) by applying slight pressure:

1. First attach the Fieldbus Coupler to the mounting rail.

2. The Bus Terminals are now attached on the right-hand side of the Fieldbus Coupler. Join the
components with tongue and groove and push the terminals against the mounting rail, until
the lock clicks onto the mounting rail.

If the Terminals are clipped onto the mounting rail first and then pushed together without
tongue and groove, the connection will not be operational! When correctly assembled, no
significant gap should be visible between the housings.

During the installation of the Bus Terminals, the locking mechanism of the terminals must not
come into conflict with the fixing bolts of the mounting rail.

3.1.2 Disassembly

Each terminal is secured by a lock on the mounting rail, which must be relea se d for disassembly:

1. Carefully pull the orange-colored lug approximately 1 cm out of the disassembled terminal,
until it protrudes loosely. The lock with the mounting rail is now released for this terminal, and
the terminal can be pulled from the mounting rail without excessive force.

2. Grasp the released terminal with thumb and index finger simultaneous at the upper and lower
grooved housing surfaces and pull the terminal away from the mounting rail.

3.1.3 Connections Within a Bus Terminal Block

The electric connections between the Bus Coupler and the Bus Terminals are automatically
realized by joining the components:

 The six spring contacts of the Standard Bus/Performance Bus deal with the transfer of the

data and the supply of the Bus Terminal electronics.

 The power contacts deal with the supply for the field electronics and thus represent a supply

rail within the bus terminal block. The power contacts are supplied via terminals on the Bus
Coupler.

12

Note

: During the design of a bus terminal block, the pin assignment of the individual Bus

Terminals must be taken account of, since some types (e.g. analog Bus Terminals or digital
4-channel Bus Terminals) do not or not fully loop through the power contacts. Power Feed
Terminals interrupt the power contacts and thus represent the start of a new supply rail.

3.1.4 PE Power Contact

The power contact labeled PE can be used as a protective earth. For safety reasons this contact
mates first when plugging together, and can ground short-circuit currents of up to 125 A.

WARNING!! Note that, for reasons of electromagnetic compatibility, the PE contacts are

For insulation testing, disconnect the PE supply line at the Bus Coupler or the

Note: The PE power contact must not be used for other potentials!

I/O Terminal / MOUNTING AND WIRING

capacitatively coupled to the mounting rail. This may lead to incorrect results
during insulation testing or to damage on the terminal (e.g. disruptive discharge
to the PE line during insulation testing of a consumer with a nominal voltage of
230 V).

Power Feed Terminal! In order to decouple further feed points for testing, these
Power Feed Terminals can be released and pulled at least 10 mm from the
group of terminals.

3.1.5 Wiring

Up to eight connections enable the connection of solid or finely stranded cables to the Bus
Terminals. The terminals are implemented in spring force technology. Connect the cables as
follows:

1. Open a spring-loaded terminal by slightly pushing with a screwdriver or a rod into the square

2. The wire can now be inserted into the round terminal opening without any force.

3. The terminal closes automatically when the pressure is released, holding the wire securely

Note: Analog sensors and actors should always be connected with shielded, twisted
paired wires.

I/O Terminal / AUTOMATIC CONFIGURATION

4 AUTOMATIC CONFIGURATION

This chapter describes the basics of automatic configuration within the KAS Integrated
Development Environment (IDE).

4.1 Scan Device

For ease-of-use the KAS IDE Scan Device feature provides automatic integration of I/O devices.
This allows you to automatically locate and add I/O terminals to the application project:

4.2 Setting I/O Values

After the I/O slice is mapped it can be selected in the application project and the offset and gain
values can be set. Additionally, the IDE allows you to map the I/O points to variables in your
application:

15

I/O Terminal / AUTOMATIC CONFIGURATION

For more detailed information on these procedures refer to the section “EtherCAT Scan Device”
in the KAS IDE online help.

16

5 MANUAL CONFIGURATION

Kollmorgen strongly recommends automatic configuration using the KAS IDE over manual
configuration. For automatic configuration refer to chapter 4. Manual configuration is for advanced
procedures only. The following sections provide the necessary configuration information to
manually map the I/O device.

5.1 Mapping in the Bus Coupler

Each terminal channel is mapped in the bus coupler. In the standard case, this mapping is done
with the default setting in the bus coupler / bus terminal. The following tables provide information
on how the AKT-ENC-000-000 maps itself in the bus coupler depending on the set parameters.

The AKT-ENC-000-000 is mapped in the bus coupler depending on the set parameters. The
terminal is always evaluated completely, the terminal occupies memory space in the process
image of the input and outputs.

latch impulse after validity of the
EN_Latch_Ext_n bit, the counter value
in the latch register is stored. The
pulses that follow have no influence on
the latch register when the bit is set.
Attention must be paid to ensuring that
the corresponding latch valid bit
(Latch_Ext_Val) has been removed
from the terminal before alerting of the
zero pulse. This functionality is

En_Latch_Ext The external latch input is activated for

positive edge. With the first external
latch impulse after validity of the
En_Latch_Ext bit, the counter value in
the latch register is stored. The pulses
that follow have no influence on the
latch register when the bit is set.
Attention must be paid to ensuring that
the corresponding latch valid bit
(Latch_Ext_Val) has been removed
from the terminal before alerting of the
zero pulse. This functionality is
adjustable in the feature register

RD_Period The periods between two positive

edges of the input A are measured with
a resolution of 200 ns. When the bit is
set, this period is output in the data
bytes D2, D3, D4. This functionality is
adjustable in the feature register.

0 En_Latch The zero point latch (C input) is

activated. The counter value is stored in
the latch register with the first external
latch pulse after validity of the En_Latch
bit (this has priority over En_Latch_Ext).
The pulses that follow have no
influence on the latch register when the
bit is set. Attention must be paid to
ensuring that the corresponding latch
valid bit (Latch_Val) has been removed
from the terminal before the zero pulse
is alerted (the Latch_Val bit cannot be
removed from the terminal until the C
pulse has a low level).

Note: For the external latch input: The activation of the positive edge (En_Latch_Ext = 1) has
priority to the activation of the negative edge (En_Latch_Ext_n = 1).

5.4 Register Description

The complex terminals can be adjusted to different operating modes or functionalities. The "
general description of register " describes the contents of the registers, which are identical for all
complex terminals.

The terminal-specific registers are explained in the following section following.
The access to the internal registers of the terminal is described in the section "Register

Communication ".

5.4.1 General Register Description

Complex terminals that possess a processor are capable of bidirectionally ex-changing data with
the higher-level control system. Below, these terminals are referred to as intelligent bus terminals.
They include the analog inputs (0-10V, -10-10V, 0-20mA, 4-20mA), the analog outputs (0-10V, ­10-10V, 0-20mA, 4-20mA), serial interface terminals (RS485, RS232, TTY, data transfer
terminals), counter terminals, encoder interfaces, SSI interfaces, PWM terminals and all other
configurable terminals.

Internally, all intelligent terminals possess a data structure that is identical in terms of it's essential
characteristics. This data area is organized in words and embra ce s 64 memory locations. The
essential data and parameters of the terminal can be read and adjusted by way of the structure.
Function calls with corresponding parameters are also possible. Each logical channel of an
intelligent terminal has such a structure (therefore, 4-channel analog terminals have 4 regi ster
sets.

I/O Terminal / MANUAL CONFIGURATION

This structure is broken down into the following areas:

Register Application

0 to 7 Process variables
8 to 15 Type register
16 to 30 Manufacturer parameters
31 to 47 User parameters
48 to 63 Extended user area

5.4.2 Process Variable

R0 - R7: Registers in the terminal’s internal RAM – The process variables can be used in

additional to the actual process image and their functions are specific to the terminal.

R0 - R5: These registers have a function that depends on the terminal type.

22

I/O Terminal / MANUAL CONFIGURATION

R6: Diagno

In the case of serial interface terminals, for example, parity errors that have occurred during data
transfer are indicated.

R7: Command register

High-Byte_Write = function parameter
Low-Byte_Write = function number
High-Byte_Read = function result
Low-Byte_Read = function number

5.4.3 Type Registers

R8 - R15 Registers in the terminal's internal ROM

The type and system parameters are programmed permanently by the manufacturer and can only
be read by the user but cannot be modified.

R8: Terminal type:

The terminal type in register R8 is needed to identify the terminal.

R9: Software version X.y

stic register – The diagnostic register may contain additional diagnostic information.

The software version can be read as an ASCII character string.

R10: Data length

R10 contains the number of multiplexed shift registers and their length in bits. The bus coupler
recognizes this structure.

R11: Signal channels

In comparison with R10, the number of logically existing channels is located here. For example,
one physically existing shift register may consist of several signal channels.

R12: Minimum data length

The respective byte contains the minimum data length of a channel to be transferred. If the MSB
is set, then the control/status byte is not necessarily needed for the function of the terminal and,
with appropriate configuration of the coupler, is not transferred to the control system. 3.2.1.1

0x16 Structure 1 byte n double words with variable logical channel length

R14: Reserved
R15: Alignment bits (RAM) – The alignment bits are used to place the analog terminal in the

Bus Coupler on a byte boundary.

5.4.4 Manufacturer Parameters

R16 to R30: Manufacturer parameter area (SEEROM) – The manufacturer parameters are

specific for each type of terminal. They are programmed by the manufacturer, but can also be
modified by the controller. The manufacturer parameters are stored in a serial EEPROM in the
terminal, and are retained in the event of voltage drop-out. These registers can only be altered
after a code-word has been set in R31.

5.4.5 User Parameters

R31 to R47: User parameter area (SEEROM) – The application parameters are specific for each

type of terminal. They can be modified by the programmer. The application parameters are stored
in a serial EEPROM in the terminal, and are retained in the event of voltage drop-out. The user
area is write-protected by a code-word.

R31: Code-word register in RAM – The code-word 0x1235 must be entered here so that
parameters in the user area can be modified. If any other value is entered into this register, the
write-protection is active. When write protection is not active, the code word is returned when the
register is read. If the write protection is active, the register contains a zero value.

R32: Feature register – This register specifies the terminal's operating modes. Thus, for
instance, a user-specific scaling can be activated for the analog I/Os.

R33 to R47 Terminal-specific Registers – The function of these registers depends on the
respective terminal type (see terminal-specific register description).

5.6 Register Communication

Register Access Via Process Data Exchange | Bit 7=1bin: Register Mode

If bit 7 of the control byte is set, then the first two bytes of the user data are not used for
exchanging process data, but are written into or read from the terminal's register set.

I/O Terminal / MANUAL CONFIGURATION

16-bit up/down counter

Input A: Counter

Input B: Counting direction (5 V or open

= up, 0 V= down)

Input C: Latch

Bit 6=0

: read | Bit 6=1

bin

bin

Bit 6 of the control byte specifies whether a register should be read or written. If bit 6 is not set,
then a register is read out without modifying it. The value can then be taken from the input
process image.

If bit 6 is set, then the user data is written into a register. As soon as the status byte has supplied
an acknowledgement in the input process image, the procedure is completed (see example).

Bit 0 to 5: Address

The address of the register that is to be addressed is entered into bits 0 to 5 of the control byte.
