Installing the movers
Two, four or six movers can be coupled with a frame. To ensure an almost linear increase in the payload, a center-to-center distance of 240 mm must be maintained from mover center to mover center. The total payload can be calculated by multiplying the number of movers by the maximum payload of a mover minus the frame weight:
Variable | Explanation |
|---|---|
A | Number of movers |
B | Maximum load of a mover |
C | Frame weight |
D | Total payload |
For further questions about mover coupling, please contact your local Beckhoff branch or Beckhoff Support:

The work required for mover coupling should be carried out by two persons. The weight and dimensions require a second person to turn and transport the mover coupling.
 | Installation example This chapter describes the mover coupling using a 2 x 2 frame and four movers APM4550-0000 as an example. |

Keep the workplace free of metallic and magnetic materials Make sure that your workplace is free of metallic and magnetic materials before positioning the mover. Only remove the mover from the transport securing device if absolutely necessary for assembly work. The transport securing device weakens the magnetic field and protects electrical components from magnetic influences. If movers are attracted by metallic and magnetic parts, serious injuries to the fingers from crushing and in the eyes from splinters can result. |
| |
Movers contain strong permanent magnets The permanent magnets are arranged in so-called Halbach arrays, which ensure that the magnetic field on the underside of the mover is significantly stronger than on the upper side of the mover. The field of the permanent magnets is present even when the power supply is switched off. If the movers attract each other and collide, serious injuries to the fingers from crushing and in the eyes from splinters can result. |

Transport the mover with the safety pictogram facing upwards Always transport the movers with the safety pictograms facing upwards. The underside of the mover must be in the transport securing device. The transport securing device weakens the magnetic field of the mover. Incorrectly inserted movers can attract magnetic objects or other movers, resulting in serious injuries to fingers from crushing and to eyes from splinters. |
- ►To safely remove the bumpers, remove the mover [1] from the transport securing device [2] and turn it by 180°
- ►Place the mover in the transport securing device [2] with the underside facing upwards
Notice | |
Permanent magnets can attract tools The permanent magnets on the underside of the movers are now exposed and can attract tools used to remove the bumpers. |
- ►Remove two screws [1]
- ►Remove a bumper [2]
- ►Remove other bumpers in the same way
- ►Place the frame [1] on the work surface with the top side [2] facing upwards
Mover alignment
All movers of the mover coupling must have the same orientation; different mover orientations are not permitted:
 | Note the orientation Before covering the first mover with an assembly aid, note the orientation of the mover in the frame. |
- ►Place the mover [1] into frame [2]
- ►Secure the mover [1] with the assembly aid [2] and four screws [3] to prevent it from falling out
Once the first mover has been secured with the assembly aid, you can insert the second mover. Make sure that the mover is in the correct position.
- ►Insert the mover [1] into the frame [2]
- ►Secure the mover [1] with the assembly aid [2] and four screws [3] to prevent it from falling out
- ►Insert and secure further movers in the same way

Two persons are required for turning the frame Two persons are required for turning the frame with the attached assembly aids. The underside of the movers is permanently magnetic and can attract other movers or magnetic parts. Failure to do so may result in serious injury to fingers from crushing or to eyes from splinters. |
- ►Turn the frame [1] with attached assembly aids by 180°
- ►Fasten the mover [1] with 20 screws [2]
- ►Observe tightening torques:
Component | Tightening torque [Nm] |
|---|---|
Screws, M3 x 6 | 1.5 |
- ►Attach other movers in the same way
| |
Two persons are required for turning and carrying the frame Two persons are required for turning and carrying the frame with the attached assembly aids. The underside of the movers is permanently magnetic and can attract other movers, mover couplings or magnetic parts. Use the assembly aids to turn and carry the mover coupling. Failure to do so may result in serious injury to fingers from crushing or to eyes from splinters. |
- ►Turn the frame [1] with attached movers [2] by 180°
- ►Carry frame to the system using the assembly aids
| |
Only hold the mover coupling at the side of the assembly aid If you place a mover coupling on the stator surface, only hold the mover coupling at the side of the assembly aids. Failure to do so may result in serious injury to fingers from crushing or to eyes from splinters. |
Notice | |
Note the alignment of the mover coupling When placing the mover coupling, make sure that the XY axes of the movers correspond to the XY axes of the tiles. Further information can be found in chapter Mover alignment. |
- ►Place the mover coupling [1] straight on the stator surface [2]
- ►Make sure that your fingers are not underneath the mover coupling [1] and that the mover coupling has sufficient distance to other mover couplings
- ►Remove the four screws [1]
- ►Remove the assembly aid [2] from the frame
- ►Remove all other assembly aids in the same way
