1.4 Liability NTI AG (as manufacturer of LinMot linear motors and MagSpring products) excludes all liability for damages and expenses caused by incorrect use of the products. This also applies to false applications, which are caused by NTI AG's own data and notes, for example in the course of sales, support or application activities.
• For non-anti-magnetic watches, keep the double minimum distance. Burn hazard The shaft of LinMot linear rotary motors can reach temperatures of 80 °C, which may cause burns upon contact. 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.

For your own safety, avoid constant contact with magnets. • Store large magnets at least one meter away from your body. Temperature resistance Keep motors away from unshielded flame or heat. Temperature above 120°C will cause demagnetization. Page 6 / 34 PR02-88 NTI AG / LinMot...
Housing Pusher LinMot linear rotary motors are direct electric drives for use in industrial and commercial installations. For correct handling, observe the warnings listed in chap. 2. The PR02 motor series is characterized by a slim design in which a linear and a rotary motor including additional components are integrated in a common housing.OptionThis features a high-precision and...
By combining linear and rotary motion, highly complex motion patterns, such as those required in sealing and assembly applications, can be easily realized using LinMot linear rotary motors. In addition to the two motors, further options such as an air feed-through, a magnetic spring "MagSpring", a torque sensor and a force sensor can be integrated in the housing.

With this option, a suitable, galvanically isolated measuring amplifier is automatically integrated in the linear rotary motor and provides a measuring signal of +-10 VDC suitable for the LinMot drive. Factory calibrations of integrated torque sensors are always carried out in the installed state. This has the advantage that the influences of the mechanics and the linear rotary motor are included.
(see explanation above). In addition, the front of the motor should be fixed using the 4 tapped holes. The positions of the tapped holes can be found in the "Dimensions" section. Page 10 / 34 PR02-88 NTI AG / LinMot...
The use of drivers or the production of grooves is completely eliminated. The suitable shaft-hub clamping type can be ordered from LinMot. Mounting instructions and ordering information can be found in the "Accessories" chapter.
Only connect or disconnect the motor connector and sensor cable if no voltage is applied to the servo drive! Only original LinMot cables may be used for wiring the motor and sensor! Even assembled cables may only be manufactured from the original LinMot accessories and must be...

(not at the transducer) if required. • External EMC circuitry A ceramic capacitor 100nF / 50V can be soldered between pins 4 - 5 on the evaluation to avoid wirebound interference. Page 14 / 34 PR02-88 NTI AG / LinMot...
The through bore-hole in the rotating shaft is Ø 4 mm. In the case of vacuum application, it is recommended to use a unit with sufficient power, as experience has shown that all air coupling points generate small losses. NTI AG / LinMot PR02-88 Page 15 / 34...
Installation Guide Linear Rotary Motors 6 Start-up Please note that motors of the PR02-88 family are only fully supported from LinMot-Talk version 6.8 onwards. It is therefore strongly recommended not to use an older LinMot-Talk version. 6.1 Linear Motor and Rotary Motor Linear motor and rotary motor are electrically independent units.
6.5 Plug and Play Function for Linear Rotary Motors LinMot linear rotary motors of the latest generation are Plug and Play capable (see motor label "PnP"). This means that they register with the drive independently. The module- and motor-specific parameters are automatically stored in the drive and the motor is ready for operation.
The various parameters for the linear motor and the rotary motor are set via the corresponding motor wizard in the LinMot Talk configuration program. To open the wizard, select the "Motor Wizard" icon in the task bar. 6.6.1 Selection of the Motor Data Files If the connected motor is a module with plug and play functionality, the following step can be skipped.
Installation Guide Linear Rotary Motors 6.6.3 Inverting the Coordinate System Starting with LinMot-Talk version 6.8 the direction of the coordinate system can be selected. Default value for rotary motors: Positive counting direction = counterclockwise (see figure chapter 6.2.1) Default value for linear motors: Positive direction of movement = Regular (see figure in chapter 6.2.2) If the coordinate system is reversed, this has an influence on the current and the force/torque of the motor.
6.6.4 Selection of the Linear and Rotary Unit System In step 4 of the Motor Wizard the GUI (Graphical User Interface) of the LinMot-Talk software can be set. This setting only affects the display of the LinMot-Talk software. The resolution and scaling of the transmission data (raw data) to the higher-level PLC are retained.
“TF Force Control” software package cannot be used. If the signal of the torque measuring shaft / force sensor is only evaluated (PLC or LinMot Drive), the software package is not necessary.
6.7.3 Initial Test of a Torque Measuring Shaft / Force Sensor It’s recommended to proceed an initial test of a sensor using the LinMot-Talk Variable before entering operational state. 1. Log into the drive using LinMot-Talk software and open the control panel.

If the value of variable “Measured Force” is changing its value within different direction as variable “Motor Current” shows please check wiring or parameter setting “Analog Force Feedback Setting”. DON’T ENTER FORCE CONTROL MODE! NTI AG / LinMot PR02-88 Page 23 / 34...

Slightly oil the shaft-hub clamping before mounting, do not use molybdenum disulphide or fat. • Tighten screws opposite each other 180 degrees offset in several steps to tightening torque T (see above for details). Page 26 / 34 PR02-88 NTI AG / LinMot...
Maintenance or disassembly of the linear rotary motors may only be carried out by trained companies: • LinMot • Companies qualified by LinMot If the linear rotary motor is not opened by one of the above-mentioned companies, the warranty claim expires. NTI AG / LinMot...
Replacement and maintenance of ball bearings / plain bearings, if necessary e) Calibration of torque measuring shaft, if necessary (The calibration of built-in torque measuring shafts is carried out at the NTI AG / LinMot factory.) 8.2.2 Inspection after each 12'000h Maintenance is recommended every 12,000 hours of operation or every two years.
