Coupling of the Actuator Slips 

Retightening the Coupling 

The metal bellows coupling is clamped by two small radial set screws to the spindle. In the rare 

case that the coupling slips, these two screws need to be retightened. To do this, the M-227 

must be disassembled. 

Requirements 

 

You have disconnected the M-227 from the electronics. 

 

You have read and understood the “General Notes on Troubleshooting” (p. 17). 

Tools and accessories 

 

1.2 mm hex key 

Retightening the coupling 

1.

 

Remove the set screw located about in the middle of the motor housing (p. 9) fixing the 

motor/gearhead assembly. 

2.

 

Turn the motor/gearhead assembly together with the cable until one of the radial set 

screws clamping the coupling bellows can be seen through the hole near the transition 

from the motor housing to the micrometer housing (p. 9) of the M-227. 

3.

 

Untighten the set screw. 

4.

 

Turn the motor/gearhead assembly until the second set screw appears beneath the 

hole. Untighten this set screw as well. 

5.

 

Now the motor/gearhead assembly can be pulled out of the motor housing. 

Important note:

 To prevent damage, avoid bending and pull forces on the bellows 

coupling. 

6.

 

Examine the connection of the coupling bellows with the gear shaft and tighten both 

fixing screws. 

7.

 

Reassemble the M-227.
