SP9047 SSPA:47 Position Coder Signal Abnormal
The A/B phase signal of the spindle position coder (connector JY4) or the A/B phase signal of the MZ or BZ sensor (connector JY2) is abnormal. The relationship between the A/B phase and 1-Rotation signal is incorrect (pulse interval mismatch). Check/adjust signals from the sensor. Replace cable or sensor.
Quick tip:
Check signals from sensors
