2.12 Absolute Multiturn Encoder
2.12.2 How to setup the mechanical zero point (quick guide).
The tab “Absolute positioning” is visible in the MacTalk program when a motor with ab-
solute multiturn encoder is connected.
The functions showed below are used to adjust and monitor the actual encoder position.
Procedure for adjusting the zero point:
1. Before mounting the motor in the application connect power to the motor.
2. Press the “Set offset = 0” button and move the motor until the “Encoder position”
shows close to 0. This is recommended to make sure that the full encoder working
range is available.
3. Mount the motor in the application and move it to the intended zero position.
4. Press the “Reset position” button to reset the “Actual position” (P_IST) and press the
“Save in Motor” button in order to store the zero point setting permanent in the mo
-
tor.
