Motor attachment with mount and coupling
A motor can be attached via a mount and coupling to all linear modules equipped with a ball screw drive.
The mount serves to fasten the motor to the Linear Module and acts as a closed housing for the coupling.
The coupling transmits the motor drive torque free of distortive stresses to the Linear Module’s drive shaft.
Our standard couplings compensate for the system’s thermal expansion.

3 Coupling
4 Linear module
Motor attachment via timing belt side drive
On all linear modules with a ball screw drive the motor can be attached via a timing belt side drive.
This makes the overall length shorter than when attaching the motor with a mount and coupling.
The space-saving, closed pulley housing provides protection for the belt and acts as a motor bracket.
In addition, various gear ratios are available.
The timing belt side drive can be mounted in four different directions.

Technical data
General technical instructions
Note on dynamic load capacities and load moments
Determination of the dynamic load capacities and load moments is based on a travel life of 100 000 m. Often only 50 000 m is actually stipulated.
For comparison:
Multiply values C, Mt and ML from the table by 1.26.
Suitable loads
Regarding the desired nominal life, in general loads for Fcomb, Fm up to around 20 % of the dynamic characteristic values (C, Mt, ML) have generally proven suitable.
See the "Calculation" document in the "Project planning instructions" chapter for the respective Linear Module.
Do not exceed the technical data for the Linear Motion System.

Example
Linear Module MKK-080: L = 3000 mm, F = 1500 N
From diagram MKK-080: f = 1.8 mm, fmax = 3.5 mm
The deflection f is significantly less than the maximum permissible deflection fmax, and no additional support is therefore necessary.
The following diagram is valid for:
- both ends firmly fixed (200 to 250 mm per side)
- 6 to 8 screws per side
- solid mounting base
- Lmax must be noted; see the "General Technical Data" table in the "Technical Data" chapter

Mounting instructions:
A mounting channel is needed to fasten the magnetic field sensors and cable guides.
This is suspended at the side in the upper slot at the linear module MKK / MKR-040 and secured with set screws.
The magnetic field sensors are pushed into the top (MKK) or bottom T-grooves (MKR) in the mounting channel and
fixed with set screws. The switch activator is a magnet (on both sides) that is integrated in the carriage (no switch bracket necessary). The switch activation points can be positioned anywhere along the stroke. For position of solenoid switch, see the linear module instructions R320103169.

Socket and plug, cable duct
Attach the socket to the side with the most switches. The socket and plug are not pre-wired. The variable sliding attachment allows switching positions to be optimized during start-up. The plug can be mounted in three directions.
Cable duct
The cable duct is fastened in the T-slots on the side of the frame. Fastening screws widen the profile and ensure that the cable duct is securely mounted.
See the illustration for the position of the slot.
The cable duct will accommodate up to two cables for mechanical switches and three cables for proximity switches.
Fastening screws and cable grommets are included.
Socket and plug
Attach the socket to the side with the most switches. The socket and plug are not pre-wired. The variable sliding attachment allows switching positions to be optimized during start-up. The plug can be mounted in three directions.
Mounting examples of switches
Determination of the switching position
Switching distance: The switching distance is the distance between the carriage center (TM) and the zero point (0) when a switch is actuated (indicated in mm). Example of a mechanical limit switch (assuming the zero point is at L/2):
Maximum switching distance = 0.5 x (max. travel distance) – excess travel = 0.5 x effective stroke
For safe operation of the linear module the excess travel must be greater than the braking path.
For MKR... and MLR...: The acceleration travel sa can be assumed as the reference value for the braking distance.
For MKK...: In most cases, the following is sufficient as a guideline value for the excess travel (braking path): Excess travel = 2 x screw lead P.
Note the smallest possible switching distance (determined by attachments):
mechanical-mechanical = 60 mm; mechanical-proximity = 45 mm; proximity-proximity = 28 mm.
for MKR-145: mechanical-mechanical = 62 mm; mechanical-proximity = 49 mm; proximity-proximity = 35 mm
The switches as well as socket with plug are fixed in the upper T-slots of the frame and actuated by a switch tab on the carriage.

Delivery notes
Form of delivery
Product generation 3:
Linear Modules with a ball screw drive or belt drive are delivered fully assembled.
Gear/motor attachment interface:
If a combination of attachment interface, gears and motor has been selected, the attachment of the components is done as shown in the figure below. When ordering Linear Modules with only an attachment interface (without gears and motor!), not all parts can be mounted. Final assembly must then be carried out by the customer. All necessary instructions and parameters for professional assembly are included. The installation version is selected and determined during product configuration, and it is a part of the order key.

Lead deviation of the ball screw drive for Linear Modules MKK, option 003
In addition to graphical representation (see illustration), a measurement report is supplied in table form.
Example diagram
| δ = deviation (μm) | |
| s = measured travel (mm) | |
Positioning accuracy as per VDI/DGQ 3441 option 005
Measurement points are selected at irregular intervals along the travel distance. This enables even periodical deviations to be detected during positioning.
Each measurement point is approached several times from both sides.
This provides the following parameters.
Example diagram
Positional uncertainty P
The positional uncertainty equals the total deviation.
It encompasses all the systematic and random deviations in relation to positioning.
Positional uncertainty is a parameter for the positioning accuracy and corresponds to the total deviation. It encompasses all the systematic and random deviations in relation to positioning.
Positional uncertainty takes the following characteristic values into consideration:
- Positioning deviation
- Reversal range
- Position variation range
Positioning deviation Pa
The positioning deviation equals the maximum difference arising between the mean values of all the measurement points.
It describes systematic deviations.
Reversal range U
The reversal range corresponds to the difference in mean values of the two approach directions. The reversal range is determined at every measurement point.
It describes systematic deviations.
Position variation range PS
The position variation range describes the effects of random deviations.
It is determined at every measurement point.
