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.

Deflection
Take note of the "General Technical Instructions" section of the "Technical Data" chapter.
The following diagram is valid for:
- both ends firmly fixed (200 to 250 mm per side)
- 6 to 8 screws per side
- fixed substructure
Example
Linear module MLR-080: L = 3000 mm, F = 750 N
From diagram MLR-080: f = 1.2 mm, fmax = 3.0 mm
The deflection f lies well below the maximum permissible deflection fmax, so no additional supports are required.

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.
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.

2 Motor
3 Mount and coupling
4 Timing belt side drive

7 Gearing
Motor connector position
- Linear Module in horizontal installation position (carriage at the top)
- View toward the motor from the rear
- For selectable motor connector locations, see "Order details" chapter, "Configuration and ordering" document.
Example:
timing belt side drive S270
Motor connector position 180°
Switching system
Magnetic sensors are included as loose parts. Further switching system components can be ordered from the range of accessory products. The exact setting of the position must be carried out before start-up. See “Mounting” chapter.
Lubrication
On delivery, Linear Modules of product generation 3 are supplied with initial greasing, preserved or prepared for connection to a central lubrication system according to the optionally selected lubricant version. For information on lubricants, see section “Maintenance”.
