Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Zero Position Sensor
The zero position of the swivel module with respect to the zero position sensor is detected by a 1/0 edge when swivelling from the direction of the off position in the direction of the optical axis. The swivel module is repeatedly calibrated during operation based on this "soft" reference point.
| Index | Explanation |
|---|---|
| 1 | Mechanical stop, minimum |
| 2 | Electrical stop |
| 3 | OFF position |
| 4 | Position of zero position sensor |
| 5 | Position of optical axis = 0 |
| 6 | Electrical stop, maximum |
| 7 | Mechanical stop |
| 8 | Swivel direction |
| 9 | Reference run from left |
Driving the stepper motor in positive direction of the swivel module corresponds to swivel movement to the right.
