Diagnosis
1. Verify if encoder power supply
voltage is DC5V ± 5% ;
2. Verify if encoder cable and shielded
layer is not damaged;
3. Verify if encoder cable is close to
high-powered power supply cable

Solution
Modify absolute encoder mode
settings
Solution
Adjust absolute value application
mode, set to turntable mode
Solution
Reduce encoder temperature.
Solution
Adjust absolute value application
mode, set to turntable mode
Solution
1. Make sure encoder power supply
voltage is stable
2. Make sure encoder cable is not
damaged.
3. Make sure encoder cable shielded
layer is grounded to frame
4. Make sure encoder cable is away
from high-powered power supply
cable
