Mover, length 55 mm and 70 mm, with spring-loaded rollers

Mover, length 55 mm and 70 mm, with spring-loaded rollers 1:

Mounting example

The mounting is described using a mover AT9014-0070-0550 as an example.

Pretensioning

Mover, length 55 mm and 70 mm, with spring-loaded rollers 2:

In delivery state the suspension strut is pretensioned by a spring vis-à-vis the mover housing on the mover AT9011-0070, so that the air gap [1] between the suspension strut [2] and the mover housing [3] is zero when removed. Only when the mover is mounted on the guide rails [4] does the pretensioning create an air gap.

Due to their design, the rollers readjust themselves in the event of wear as a result of the pretensioning of the spring. For more information, see the chapters Roller wear on AT9014-0055 and Roller wear on AT9014-x070 and AT8300-1x00.


Mover position during mounting

Mover, length 55 mm and 70 mm, with spring-loaded rollers 3:

The guide rollers [1] have a greater distance to each other on the 70 mm mover due to its design. In order to be able to install the mover over the rail on support [2], the mover must be rotated and placed on the rail on support.

Notice

Removing the NCT electronics

Before commissioning a system with No Cable Technology for the first time and before commissioning new motion profiles, the NCT electronics must be removed from the movers to avoid collisions. The NCT electronics can only be mounted on the movers once all the motion profiles are working in operation.

Remove the NCT electronics from the movers before initial commissioning and before commissioning new motion profiles.

Test all movement profiles of the movers without the NCT electronics mounted.

Only mount the NCT electronics after all motion profiles are working.

If you are using movers with NCT electronics mounted, you must remove the NCT electronics before installing the movers on the rails. Further information can be found in chapter Replacing NCT electronics.

Mover, length 55 mm and 70 mm, with spring-loaded rollers 4:
►Position the mover [1] with the encoder flag [2] centrally above the rail on support [3]
►Ensure that the encoder flag [2] is correctly aligned with the name plate [4]
Mover, length 55 mm and 70 mm, with spring-loaded rollers 5:
►Make sure the guide rollers [1] of the mover are not pressed onto the edges [2] of the rail on support during mounting

WARNING

Risk of crushing due to strong magnetic attraction

When mounting the movers on the rails, always hold them tight with both hands. The magnetic plate set of the mover and the modules strongly attract one another magnetically.

If you do not hold the movers tight with both hands in a controlled manner, the magnetic forces can attract the movers in an uncontrolled manner to the motor modules and cause serious crushing injuries to the hands and fingers or damage to the system.

Mover, length 55 mm and 70 mm, with spring-loaded rollers 6:
►Carefully place the mover [1] in the center of the rail on support using light pressure and both hands
►Note the rotated position when mounting
►Ensure that the magnetic plate set [2] and the module [3] attract each other magnetically as soon as the magnetic plate set of the mover comes close to the module
►Move the mover to a straight position




Mover, length 55 mm and 70 mm, with spring-loaded rollers 7:

The mover must be pressed downwards when it is rerouted out of the rail on support onto the guide rail, as the upper guide rollers [1] and the lower guide rollers [2] are too far apart due to the suspension strut and the upper guide rollers will otherwise collide with the edges of the rail on support [3].

The pressure on the mover housing [4] moves the suspension strut [5] with the lower guide rollers upwards. The distance between the upper and lower guide rollers is reduced and an air gap [6] is created between the mover housing and the suspension strut.

Mover, length 55 mm and 70 mm, with spring-loaded rollers 8:
►Carefully push the mover [1] out of the rail on support by hand with light pressure along the guide rail [2]

The mover is now mounted on the guide rail.

►Mount all further movers in the same way
Mover, length 55 mm and 70 mm, with spring-loaded rollers 9:

When all remaining movers have been mounted:

►Check all round that the air gap between the magnetic plates [1] of the movers and the modules [2] is symmetrical on both sides of the system and is approximately 0.85 mm
►Check all around that the air gap between the encoder flag and the modules is approximately 0.90 mm
►Check that the magnetic plates and the encoder flag are positioned parallel to the modules
►Remove the rail on support [+] and mount the lock
