I have set the sequence settings of PCR-LE series as follows: the output voltage is set to 200 V and the voltage range is set to L. If I change the sequence setting to the H range, can PCR-LE series output 0 V?

Yes, PCR-LE series can output 0 V in the H range.
Please change the voltage range to H based on the set voltage of the sequence.
If not, the error code +202 “Operation denied” may appear due to a mismatch between the voltage range and the set voltage of the sequence.
