* In the USER control and the SERIAL communication control
Use the LEVEL signal at 10.0 Vmax in the P-control, 10.0 Vmax in the I-control and 5.34 Vmax
in the V-control.
If the above-mentioned level is exceeded, ERROR is produced and the output is stopped.
The 1,000V rated output voltage model is 10.0 Vmax in the P-control, 8.00 Vmax in the I-control,
and 6.67 Vmax in the V-control.
