2 Function description of the module
2.1 General functions
AXL F CNT2 INC2 1F / AXL F CNT2 INC2 XC 1F
The module is designed for use within an Axioline F station. It is used to acquire digital input
signals.
The module consists of two counter inputs (CNT) and two incremental encoder inputs
(INC). In addition, it has two digital outputs (Out1/2) which can be controlled either over a
CNT channel or an INC channel or, as an alternative, using process data.
The module has inputs which can be used to perform the following functions:
– Controlling the counting: gate inputs G1, G2,
– Changing the counting direction or stopping the counting process: direction/stop inputs
Dir1, Dir2
– Latching specific values: latch inputs L1, L2
– Referencing: reference inputs Ref1, Ref2
As an option, these inputs can be used as digital inputs, for instance, to connect limit
switches.
You can start up the module with the default parameterization without having to
parameterize it. In this case the INC channels are deactivated.
But you can also parameterize the channels with the engineering tool or with the PDI object
0080hex. The new parameterization is stored retentively. Thus, it will still be available after a
voltage reset.
AXL F CNT2 INC2 XC 1F
Thanks to special engineering measures and tests, the module can be used under extreme
ambient conditions (see module-specific data sheet).
Please refer to the module’s data sheet for the technical data of the module including the
terminal point assignment and meaning of the diagnostic and status indicators.
It can be downloaded at phoenixcontact.net/products.
When the module is reparameterized, all channels will be stopped and then
reparameterized. All channels will always be reinitialized, even if you have changed only
one channel.

Function description of the module

2.2 Features of the channels
2.2.1 CNT channels
– Detecting digital input signals with an input frequency of up to 300 kHz (one channel
wired) or 100 kHz (more than one channel wired)
– Counting the digital input signals with a 32-bit counter (up and down)
– Controlling the counting via a control input (gate) or starting and stopping the counting
via process data
– Output control according to two limit values
– Single or periodic counting is possible
– Starting the counting process via the gate signal and stopping the counting via a
separate input (direction/stop input)
– Specifying the counting direction via an external input or via process data
– Specifying a start value and an upper or lower limit is possible. The start value is loaded
when the channel is restarted or reset.
2.2.2 INC channels
– Detecting digital signals of symmetrical or asymmetrical incremental encoders (5 V or
24 V) with an input frequency of up to 300 kHz (one channel wired) or 100 kHz (more
than one channel wired)
– Position detection with a 32-bit counter
– Double or quadruple evaluation of encoder signals
– Evaluating linear or rotary axes (determining the direction of rotation or motion)
– Storing of up to two intermediate values via an external input signal (latch input Lx)
– Detecting an overflow or underflow with linear axes
– Output control according to two limit values
– Various methods to set a reference point
– Monitoring the increments by evaluating the Z signal of the encoder, in order to
determine an error of the encoder
– Hardware monitoring of the encoders
– Monitoring of the encoder supply
– Open circuit detection
– Detecting faulty electrical signals with symmetrical encoders

2.3 Maximum input frequencies
The maximum input frequency that can be used for operation depends on the wiring of the
channels and whether the Z signal, in the case of a linear axis, is to be monitored via the
firmware or not.
Table 2-1 Maximum input frequencies
Condition Maximum frequency
One channel wired 300 kHz
More than one channel wired 100 kHz
Z signal monitoring via the firmware 100 kHz

2.4 Counter channel functions
The two counter channels (CNT) acquire and process digital input signals with a maximum
input frequency of up to 300 kHz (one channel wired) or 100 kHz (more than one channel
wired).
The two channels have the same structure and the same functions.
Each of the channels has a counter input (source), a control input (gate) and a direction/stop
input (Dir/Stop).
The control and the direction/stop inputs can be used as digital inputs if they are not used
directly by the channel. The status of the inputs is mapped to the process data, no matter
whether they are used by the CNT channel or not.
There is an additional output available which can be controlled according to the
parameterization (see Section “Output control” on page 22).
2.4.1 Counting functions
The digital input pulses at the counter input (S1/S2) are counted. Depending on the
parameterization, the counter direction is either specified by the controller or by the direction
input.
The following values must be defined during parameterization:
– Start value
The start value is loaded when the channel is restarted or reset.
The start value may be any value in the possible counting range of the 32-bit counter.
– Limit values: lower and upper limit
The lower limit must always have a smaller value than the upper limit.
During operation you can change the limit values online via the process data. These
changes are not stored retentively.
How to make changes via process data, see Section “OUT process data” on page 23,
SetNewLimitsx bit.
– Type of counting: single or periodic
Single counting means that the counter counts once from the start value to the upper
or lower limit.
Periodic counting means that the counter counts periodically between the upper and
lower limit. Once a limit is reached, counting continues further from the other limit.
– Output behavior
When one or both limits are reached, an output can be controlled according to the
parameterization (see Section “Output control” on page 22).

2.4.2 Counting depending on the position of the start value
Example 1: Start value between the lower and upper limits
If the start values is between the lower and upper limits, the counter value is also between
these limits.
Figure 2-1 Counting with a start value between the limits
Example 2: Start value outside the lower and upper limits
If the start value is outside the lower and upper limits, it is possible to count in both
directions. If one of the maximum limits (0000 0000hex or FFFF FFFFhex) is exceeded, the
counting continues further from the other maximum limit (see example 2b). If the counter
value is then between the lower and upper limits, the counting continues between these
limits according to the parameterization and the counter status does not leave these limits.

reaching the maximum limits
