Guide to connect the actuator to BusLink
Actuators with IC - Integrated Controllers from LINAK®can be configured via the BusLink Configuration Software.
Please follow the three steps to connect your actuator to BusLink.
1Start by downloading the free BusLink software here:

12V or 24V
In order to connect your actuator
to the PC tool you will need two
separate cables:
1 USB2LIN cable.
1 interface cable.
Start by connecting the two cables.
Please note that the cables must
be purchased separately from the
actuator.
Before connecting the power
supply:
Connect the interface cable to the
actuator...
When changing the actuator’s signal cable with the BusLink cable, it is important that this is done carefully in order to protect
the plugs and pins. Please make sure that the plug is in the right place and fully pressed in before mounting the cable lid.
Cable connection
... and plug in the USB2LIN
cable to your computer or
laptop. Afterwards, please open
the BusLink program on your
computer.
The green diode on the
USB2LIN will now flash, but
please be aware that the BusLink
program is still in a disconnected
mode.
Finally, connect your power
supply to the actuator.
A few seconds will pass before
the connection to BusLink is
established and the actuator is
ready for configuration.

Configure the IC actuator with BusLink 2 software
Configure:
The actuator can be controlled from within the software using the buttons at the bottom of the screen. These
controls are available at all times. The “Run In/Out” buttons will run the actuator to the limits, real or virtual.The
step controls will move the actuator in selectable increments. The “Run To” function will move the actuator to an
arbitrary specified position.The actuator’s current status is shown on the right. These values are actively recorded
in a graph that will be explained later in this user guide.
Once connected, you will be able to click on one of three tabs in the top left. If you select CONFIGURE,
this screen will appear:
The overview will give you read-only information about the currently implemented parameters that can be
edited. Each parameter can be modified by clicking on the menu item to the left. Any changes made will be
shown in the “Unapplied Changes” box and will remain until you “Apply” the changes to the actuator.

Calibration
Initialize In/Out
To begin calibration, simply click on the “Service” tab at the top of the window, then select “Calibration” on the
left menu.
Once this process is complete, you’ll find that the position is now available.
The IC platform uses hall effect sensors to determine the actuator’s exact position along its stroke length. If once
connected, the actuator’s position status is displayed as “Not available”, then the actuator must first be calibrated
to use the full control functionality within the software. A calibration is required each time new parameters have
been applied for the actuator’s behavior. Calibration happens automatically whenever the actuator hits a limit
switch, so it is not necessary to be connected to BUSLINK for this to occur.
From here, determine where your actuator’s current position is. If the actuator is fully extended, then select
“Initialize In” to run the actuator to the inwards limit switch. If the actuator is fully retracted, then select “Initialize
Out” to run the actuator to the outwards limit switch. If the actuator is somewhere in between fully extended and
fully retracted, selecting either “Initialize In” or “Initialize Out” will successfully calibrate the system.

Controls
Current Limit:
The current limit can be edited as a value or percentage for both directions.
The maximum current will not exceed the maximum factory settings.
Note: If the actuator operating temperature reaches O0C/320F, the current limits are removed.
Virtual Limit:
A virtual end stop can be selected for either the inward or the outward direction.
Only one virtual limit can be selected.

8
Controls
Speed:
Soft Stop:
Soft Start:
The speed percentage can be adjusted as a motor voltage percentage.The lowest recommended speed is
60% to ensure that the actuator will push the rated load.
With a soft stop, you select a time-frame for the actuator to slow down to zero after the stop signal is applied.
The time can be set between 0 (hard stop) and 30 sec, with the exception of: 0.1-299 ms. The reason for this, is
that the actuator is unable to redirect/consume the accumulated energy in a 0.1-299 ms stop.
The soft start is similar in function to the soft stop, but can be fully configured between 0-30 sec.

Feedback types
Single Hall:
PWM:
The IC Actuator can supply the user’s control system with one of several types of feedback listed below,
depending on model:
Single hall can be selected but there are no changeable user modifiable parameters.
The pulse width modulation (PWM) type is configurable with three parameters:
“PWM Feedback In” sets the percentage of the pulse for the IN “End of Stroke” (EOS) postion.
The “PWM Feedback Out” sets the percentage pulse for the outermost position. Typical settings are 10% IN
and 90% OUT.The feedback resolution is improved by having a wider pulse percentage range. The available
base frequency range for PWM is 75-150 Hz.

Feedback types
Current Feedback:
Voltage Feedback:
The position of the actuator can be correlated to current output. The available current range is 4-20 mA.
The user can select values in the whole range but the highest resolution is achieved with the widest current
range. The minimum setting is the IN EOS or virtuel limit in position and the maximum is the OUT EOS or
virtuel limit out.
The position of the actuator can be correlated to a voltage output as well. The available voltage range is
0-10 V.The user can select any set of values in that range but the highest resolution is achieved with the
widest voltage range. The minimum setting is the IN EOS or virtuel limit position and the maximum is the
OUT EOS or virtual limit out.
