Operation Mode
Voltage drift:
When voltage drift occurs, the voltage level defined as zero voltage is different from the set zero
point. To fix this problem, you can use DOF1 (P4.020) and DOF2 (P4.021) to calibrate the offset

voltage output. The voltage level for analog monitoring output is ±8V. If the output voltage
exceeds the range, it is limited within ±8V. The resolution is approximately 10 bits, which is
equivalent to 13 mV/LSB.
