2 Safety Instructions
Contusions
Sliders contain neodynium magnets and have a strong attractive force.
Careless handling could cause fingers or skin to become pinched between two sliders.
This may lead to contusions, bruises, and bone fractures.
When handling sliders, wear thick protective gloves and keep a minimum distance between
sliders. Refer to the "Minimum distance from slider" section for minimum distance.
To reduce the risk of injury, never more than one slider should be held or transported by the
same person without packaging.
Pacemaker / Implanted Heart Defibrillator
Sliders could affect the functioning of pacemakers and implanted heart defibrillators. For the
duration of a strong approach to a magnetic field, these devices switch into test mode and
will not function properly.
•If you wear one of those devices keep the following minimum distances between the
pacemaker / defibrillator and slider:
- Min. 250 mm (10ʺ) for slider Ø 27 mm and 28 mm (PL01-27 / 28 / PL10-28)
- Min. 150 mm (6ʺ) for slider Ø 19 mm and 20 mm (PL01-19 / 20)
- Min. 100 mm (4ʺ) for slider Ø 12 mm (PL01-12)
•Inform others who wear these devices to comply with these minimum distances!
Caution - Risk of Electric Shock !
Before working, make sure that there are no high voltages.
Fast-moving Machine Parts
The sliders of LinMot linear motors are fast-moving machine parts. All necessary
precautions must be taken to prevent persons approaching the moving elements during
operation (provide covers, guards, etc.).
Automatic Restart
The motors can start automatically under certain cricumstances!
If necessary, a corresponding warning symbol must be provided and protection against
entering the hazardous area or a suitable safe electronic disconnection must be provided!
Risk of Injury due to a Defect or Fault
For areas where a defect or fault can result in substantial property damage or even serious
personal injury, additional external precautions must be taken or devices must be installed
to ensure safe operation even if a defect or fault occurs (eg. suitable safe electronic
disconnection, mechanical interlocks, barriers, etc.).
Magnetic Field
Magnets integrated in the sliders produce a strong magnetic field. They could damage TVs,
laptops, computer hard drives, credit and ATM cards, data storage media, mechanical
watches, hearing aids, and speakers.
•Keep magnets away from devices and objects that could be damaged by strong
magnetic fields.
•For the above mentioned objects, keep a minimum distance as described in the
"Pacemaker / implanted defibrillator" section.
•For non-anti-magnetic watches, keep the double minimum distance.

Combustibility
When machining magnets, the drilling dust could easily ignite.
Machining the sliders and the magnets they contain is not permitted.
Burn Hazard
During operation the slider can become hotter than 100 °C, which can cause burns if
touched. All necessary precautions (e.g. covers, casing, etc.) must be taken to prevent
contact with persons in the vicinity of the slider during operation.
Grounding
All metal parts that are exposed to contact during any user operation or servicing and likely
to become energized shall be reliably connected to the means for grounding.
Mechanical Handling
Neodymium magnets are brittle and heat-sensitive.
Machining the sliders and the magnets they contain is not permitted.
•Colliding magnets could crack. Sharp splinters could be catapulted for several meters
and cause eye injury.
•By machining the sliders, heat would result which demagnetizes the magnets.
Slider
Linear motor sliders consist of a high-precision, thin-walled stainless steel tube in which the
neodymium magnets are housed. The LinMot sliders should be handled with care.
Avoid contact with other sliders or iron parts as this can damage the magnets and the slider
surface. Do not grip the sliders with pliers, as this can also damage the surface. Do not use
sliders which are already damaged on the surface (scratches, deformation, etc.). This can
cause further damage to the stator.
Effects on People
According to the current level of knowledge, magnetic fields of permanent magnets do not
have a measurable positive or negative effect on people. It is unlikely that permanent
magnets constitute a health risk, but it cannot be ruled out entirely.
•For your own safety, avoid constant contact with magnets.
•Store large magnets at least one meter away from your body.
Temperature Resistance
Keep slider away from unshielded flame or heat.
Temperature above 120°C will cause demagnetization.

4.3.2 Connection to C1252 Servo Drive
The DSUB connector of the force sensor can be connected directly to the C1252 Drive via the X3 MOT
SENSOR interface.
5 Commissioning
5.1 Initial Commissioning of the Force Sensor
An optionally mounted force sensor is a high-precision measuring device and must be
handled accordingly. Incorrect handling, e.g. driving in to the mechanical stop, will cause
collisions that may exceed the maximum force defined in the data sheet. Incorrect handling
of the measuring device can damage the sensors.
It is strongly recommended to carefully follow the initial commissioning steps and test the
correct functioning of the measuring device before using it in real application.
5.1.1 Technology Function Force Control" Software Package
If a closed control loop is to be implemented via a sensor (force control of a motor by means of sensor
feedback to the LinMot Drive), it is mandatory to order the "TF Force Control" software package (art. no.:
0150-2503).
Without this software package, it is not possible to control a specific force or to use the drive commands of
the "TF Force Control" software package.
If only the signal of the force sensor is evaluated (PLC or LinMot Drive), the software package can be
dispensed with.
5.1.2 Setting the Parameters for Force Control at C12x0
Logged into the drive, you will find all the parameters to be set in
the LinMot-Talk software under the path "Parameters -> Motion
Control SW -> Protected Technology Functions -> Analogue Force
Feedback Control".
Parameter Tree: Input Selection
Please select the following setting under "Input Selection":
•Input Selection (UPID 150Fh) = Diff Analog Input On X4.10/X4.11
Parameter Tree: Analogue Force Feedback Config

Installation Guide Force Sensor Modules EN
Page 14 / 25 DM01-23-FS / DM01-37-FS / DM01-48-FS NTI AG / LinMot
Due to the definition of the DEFAULT positive direction of the stroke, it is recommended to
invert the +-10VDC signal via software. This means that for the parameter "0V/-10V Force"
the positive maximum value and for the parameter "+10V Force" the negative maximum
value of the force sensor is set.
By changing the direction of the stroke, the setting of the parameters "0V/-10V force" and
"10V force" must also be changed.
•0V/-10V Force (UPID 1501h) = Positive maximum value (e.g. 500 N)
•10V Force (UPID 1502h) = Negative maximum value (e.g. -500 N)
•Speed Filter Time (UPID 150Ah) = 1000µs
•Acceleration Filter Time (UPID 150Dh) = 1000µs
Parameter Tree: Force Control Parameters
The parameters for the force control loop are set here. A PID controller, a few pre-control parameters (FF
parameters) and a parameter for limiting the maximum control current (Force Ctrl Max Current) are available
for this purpose.
Work with a pure I controller at the beginning to prevent the motor from oscillating during
torque control.
Limit the maximum control current in order to avoid any possible damages during
commissioning.
5.1.3 Initial Testing of a Force Sensor
It is recommended to perform an initial test of a sensor with the LinMot talk variables before reaching the
operating state.
1. Log in to the Drive with the LinMot Talk software and open the "control panel".
2. Switch on the motor with the "Control Word" (Switch On). The motor remains in position control
mode.
3. Add the variables "Target Force" and "Measured Force" (MC SW Force Control) via the "Add
Variable" button.

Installation Guide Force Sensor Modules EN
NTI AG / LinMot DM01-23-FS / DM01-37-FS / DM01-48-FS Page 15 / 25
4. Now gently push or pull the linear axis. The variable "measured force" should rise or fall according to
the variable "Motor Current".
•If no change can be detected within the Measured Force variable, check the wiring of
the sensor.
•If the value of the variable "Measured Force" changes in a different direction than the
variable "Motor Current" shows, please check the wiring or the parameter setting
"Analog Force Feedback Setting".
DO NOT SWITCH TO FORCE CONTROL MODE!
When controlling hard objects (e.g. metal), impulses occur on impact which can cause
lasting damage to the sensor. It is recommended to reduced speed or insert a damping
insert between the sensor and the object to be pressed. Impulse measurements should be
avoided if possible.
5.2 Special LinMot-Talk Functions
5.2.1 Tare Function
By means of the tare function, undesirable measuring influences during movement, e.g. sliding friction, can
be eliminated. At standstill, it is used to zero the offset, e.g. caused by a vertical load mass.
In sensitive measuring applications, the cyclical use of the tare function is recommended. In
this way, changes in the friction or in the mechanics are continuously detected or calculated
out of the actual measurement.
Changes can occur due to temperature influences, for example.
The tare function is triggered by a special move command (for details see Motion Control Manual 0150-
1093-E). It records the measured force (UPID 0x1EA1) during the maximum, constant speed and
automatically saves its average value as an offset (UPID 0x1798). The subsequently determined force of the
sensor is thus cleansed of influences and enables more accurate measurement results.
The function allows you to define the capture time for averaging and to delay the start time of the
measurement (time delay). This allows undesired erroneous measurements, e.g. caused by the acceleration
of the motor, to be faded out.

Installation Guide Force Sensor Modules EN
Page 16 / 25 DM01-23-FS / DM01-37-FS / DM01-48-FS NTI AG / LinMot
5.2.2 Speed limiter function
The speed limiter function limits the maximum speed in closed-loop force and torque control as well as in
current command mode. This function can prevent uncontrolled acceleration of the motor in the event of
incorrect manipulation or a sudden drop in the feedback or measurement signal in the closed control loop,
thus preventing mechanical damage and injuries.
•If the speed limiter function is deactivated, the motor can accelerate uncontrolled in
force, torque and current control mode until the feedback or measurement signal is
equal to the specified setpoint.
•To minimise mechanical damage as well as the risk of injury, the use of the speed
limiter is recommended.
The maximum speed for force, torque and current control is defined
under the "Speed Limiter" tab. If the parameterised speed "Speed
Limit" is exceeded, the drive automatically switches to position
control and regulates the current speed to the defined value. The
"Speed Limiter Abort Force" parameter defines the measured value
below which the drive switches back to force, torque or current
control. If the "Speed Limit" parameter is set to 0 m/s, the function is
deactivated.

be used to clean the surface and the gap between the primary and secondary sides of the sensor module.
Sensor modules cannot be dismantled without invalidating the calibration certificate.
7.3 Lubrication
The guide elements integrated in the sensor module are provided with initial lubrication and do not need to
be relubricated.
7.4 Calibration
The force sensors are supplied with a factory calibration certificate (valid for 2 years). After initial
commissioning, it is recommended to have the sensors calibrated annually by LinMot.
Cyclical recalibration is a recommendation for applications in normal operation. Depending on customer
requirements and applications, this cycle should be adapted.
•Recalibration is also recommended if the zero point of the sensor changes for no
apparent reason.
•Recalibration is strongly recommended after improper handling. This also applies after
the occurrence of a strong mechanical load (e.g. impact).
•If the sensor housing is opened, the validity of the calibration expires.
