Changing the direction of a roller shutter motor: how it works

Updated: 07.11.2026

In brief: If the roller shutter moves down when you press “up”, the direction is reversed. On a cable motor the brown and black wires are swapped at the switch; on a radio motor the direction is reversed in setting mode via the transmitter.

Cable motor (230 V)

1. Switch off the fuse.
2. Swap the brown and black wires at the blind switch – this work is done by a qualified electrician.
3. Switch the fuse back on and test.
4. Check the end positions: with mechanical end positions, each adjusting screw belongs to one direction.

The wire assignment is explained in Connecting a roller shutter motor.

Radio motor

1. Activate setting mode (key sequence as per instructions).
2. Reverse the direction – usually by pressing up and down at the same time or with a dedicated button.
3. Save and check the end positions.

On the A-OK AM45 radio the direction is set during pairing and can be changed in setting mode.

When is the direction wrong?

• after installation on the other side of the shaft
• after replacing the motor
• after work on the switch

Frequently asked questions

Can I change the direction on the motor itself?

Not on cable motors – the swap is made at the switch. On radio motors, yes, via the transmitter.

Do I have to reset the end positions afterwards?

Check them in any case. With electronic motors, teaching them again is often necessary.
