1.0 INTRODUCTION
The Danfoss HFX product family is a series of advanced,
CAN- based controllers for use with mobile and industrial
equipment. Using C programming, these controllers
enable functional control over electrically operated
components within a variety of applications (e.g.
agricultural, construction, material handling). It is
recommendedthat an individual have experience with
control engineering and programming with C before
using this hardware.
The HFX product family is optimized for reliable
operation in severe environments, possessing
IP and temperature ratings that exceed existing solutions
from competitors. HFX controllers employ several
advanced technologies (e.g. I/O with variable conguration
architecture), enabling simple management and enhancing
both ease of use and functionality.These controllers are
intended as both a standalone solution, or as the
centerpiece to a complete control system that can include
other CAN-based devices such as displays and keypads.

4.0 SAFETY CONSIDERATIONS
Note: This operating and installation manual is intended for use
by a competent programmer, electrician, technician, or
engineer. The instructions included in this manual should be
read and kept as a reference document prior to initial
controller installation and use. Incorrect operation of these
controllers can present a signicant threat to both individuals
and equipment. In the event of an equipment breakdown, do
not attempt to repair the controller as there are no user
serviceable parts inside the enclosure. Any evidence of
tampering will invalidate the warranty.
5.0 APPLICATION
This operating and installation manual should be used in
conjunction with the hfx_capi_manual.pdf. Together, this
information should form a basis for the simple conguration of
the controller and the creation of programs specic to your
application needs. Proper operation ofthe controller is
dependent on the program thatis created and ultimately
downloaded to the hardware, therefore extensive testing is
required. Customers programming the controller possess the
responsibility of ensuring that both the hardware and software
performs as intended with their applications.
Note: That each controller within the HFX product family requires the
installation of the HFXC-API SDK, service tool and CAN adapter drivers
before initial use in the application environment. The HFXC-API SDK
requires MS Windows® 7 or greater
.
6.0 HARDWARE DESCRIPTION

9.0 GETTING STARTED
9.1 FIRMWARE
Install the Firmware
HFX units are shipped blank, with no rmware loaded. Prior to
rst use, it is necessary to load rmware to the HFX.
Launch the HFX Service Tool if it is not already open. On the main
page of the service tool select File- >Reprogram Firmware.
Select the appropriate rmware to load based on the model of
the controller intended for use.
The rmware should complete the installation process. If the
wrong rmware has been selected, the software will provide a
prompt which indicates that the rmware does not match the
controller hardware. If this occurs, verify that the correct rmware
was selected. There are two controller types, CODESYS and C- API.
The CODESYS rmware versions are the les with names ending in
0_HFXMxx through 3_HFXMxx. The C-API versions go from
4_HFXMxx through 7_HFXMxx. The software should then load on
the controller and complete installation. You should now be ready to
proceed with the application software installation
9.2 CREATING AN APPLICATION
Refer to the hfx_capi_manual.pdf and the example code
to adapt theHFX C-API SDK to your projects particular needs.
9.3 INSTALL APPLICATION
Option 1: Install application (HFX service tool)
Launch the HFX Service Tool if it is not already open.
On the main page of the service tool select
File>Reprogram Application.
Select the *.HFX le from the project folder. The*.hfx
le is located in the Build_<project_name>\ output
directory of the project folder.
Option 2: Install application (FXST service too l)
Launch the FXST service tool (NW.exe) and connect to
the controller by pressing the button, then select the
button and then select the C- API application option.

HFX Product Family
HFX Product Family Installation and Operation Manual for Matlab® Support Package January 2017 13
10.0 FUNCTIONALITY AND BASIC OPERATION
At initial startup, the controller enters the bootloader. A
bootloader is simply a small program that loads the rest of
the rmware when the controller is initially powered up.
This rmware resides in the ash memory and provides
the necessary memory mapping and instructions for the
controller, allowing the application program to be
processed. The bootstrap mechanism providesthe means
to enter the bootloader. The bootstrap mechanism is as
follows:
1. Check for PWM1&2 11.0 V
2. Delay 3 seconds
3. If the HFX service tool is connected,
abort and don’t load app from ash
4. Otherwise, load and runthe app in
ash like normal.
This provides a mechanism to remove a
frozen application.
1. Load a new application, or
2. Reset origin will clear entire application memory.
10.1 SLEEP MODE (TIME DELAY OPERATION)
Sleep Mode provides a mechanism to have a controlled shutdown
of the vehicle control system. This is a benet because the unit can
be put into an idle state where less current is required thus
extending battery life. Itis also useful with applications where,
prior to shut down, the controller needs to return key functional
outputs to a predened or home position.
10.2 CONTROLLER STARTUP
The controller will transition to the shutdown state and then
enter sleep mode after 5 seconds of the ignition pin being low.
The controller will awaken from sleep if {Sleep is low or not
connected} and {IGN is high}
Sleep current 2.4 mA, @ 10 V, 1.9 mA @ 15 V, 1.6 mA@
20 V, 1.2 mA @ 25 V
10.3 TASK CONFIGURATION
The controller supports the following tasks:
Cyclic: Task processed in a predened time.
There are 3 pre-dened task: 1 ms, 5 ms, 50 ms
Freewheeling: Task processed as soon as theprogram
is started. When complete, it will automatically restart
in a continuous loop. "Background" is the only
freewheeling task available.
State Machine Tasks: Task processed in the 1 ms loop
time, only one task is active at a time and depends on
the state machine transitions.
Note: There are no external events available to trigger task
execution. for more information on the tasks, open the help for
the HFX Application block.

10.4 WATCHDOG OPERATION
Watchdogs are present to provide an indication that something has gone wrong. Systems that are
programmable can hang for a number of dierent reasons. One of the most common is the execution of an innite loop due to a programming logic
error. This type of failure prevents any of the other code from executing. Also, if an unusual number of interrupts arrives during a single cycle of the
loopthis can prevent the main loop from having sucient time to execute. Another possibility is a failure in hardware thatcauses a constant reset.
Each controller has an internal hardware watchdog that is continuously running in the background to monitor
for a system malfunction. This watchdog is not user serviceable and is not visible to the user. It will trigger in the event of a task timeout and can only
be reset through a hard reset of the controller, which means that the user must connectthe service tooltothe controller, tie PWM 1 & 2 to supply
voltage, and then power up the unit. This will prevent the application code from loading
10.5 CONTROLLER MEMORY
The controller utilizes an advanced superscalar
32 Bit processor operating at 200 MHz. The memory is arranged into the following areas:
ROM Flash 3.75 Mbyte
EEPROM128 kbyte reserved for internal use i.e. rmware/bootloader
RAM 256 kbyte
MRAM 32 kbyte (4kbyte user accessible calibration parameters)

• Make sure that voltage drops are kept within reasonable
levels under maximum continuous load conditions e.g. 1
volt on 12-volt systems and 2 volts on 24- volt systems.
• Verify that the harness is constructed to meet the needs
of the application environment
(e.g. shock, vibration, moisture, temperature, chemicals,
and impact).
• Make certain that the harness is designed and constructed
to minimize induced interference resulting from EMI
coupling between signal wires.
• Separate power circuits from low- level signals.
• All splices (soldered or crimped) should use adhesive
lined heat shrink tubing.
• Make provisions for drip loops to attach devices in
exposed locations and prevent moisture entry and
formation.
• Provide sucient clearance from moving parts.
• Wires routed through holes in the vehicle body/chassis

should use grommets.
• Avoid sharp metal edges, fasteners, and other abrasive
surfaces or use protective shielding when routing harness
assembly.
• Route wires to avoid exhaust system components or other
high temperature areas, use appropriate heat shielding or
other insulation where routing is a problem.
• Avoid routing near wheel wells or provide adequate
mechanical protection to the assembly.
• Use a protective fuse sized appropriately for the
controller supply current.
Note: typical maximum load current is 60%- 80% of fuse
rating. Verify that wiring can handle more current than the
fuse rating. Note the following guideline for maximum
fuse recommendations:
• All Units: +VBat = 2 A
• HFX48 :+Load total < 50 A depending upon anticipated
load requirements.
• HFX32: +Load total < 42 A depending upon anticipated
This section contains information about the controller
connectors and pin outs. Please use the following
recommended wiring practices when installing and using the
controller:
• Ensure correct and adequate single point ground to
prevent ground loops.
• Use twisted or twisted shielded pair cable forCAN
per the applicable standard.
• Conrm that the CAN network is properly terminated
using 120resistors.
Ensure the appropriate sized conductor cross section is
specied for the intended load current in the harness
design.

load requirements.
• HFX12: +Load total < 26 A depending upon anticipated load
requirements.
! Warning: Prior to Welding
In order to avoid damaging the HFX controller ensure that all electrical
connectors are fully disconnected from the HFX controller prior to
