● Gear ratio = p29248 : p29249 = 1 : 3
● The absolute encoder can count eight encoder revolutions
● Position tracking function is deactivated (p29243 = 0)
For each encoder overflow, there is a load-side offset of 1/3 load revolution, after three
encoder overflows, the motor and load zero position coincide again. The position of the load
can no longer be clearly reproduced after one overflow.
In this case, if you activate the position tracking function (set p29243 = 1), and set the virtual
multi-turn p29244 = 24, the gear ratio is calculated with the encoder actual position value.
Note
Be sure to perform the "ABS" function a
gain after you set p29243 to 1.
