In the inverter, the PID control values set by the UP/DOWN control are maintained internally, and
when the operation is resumed (including when the power is turned ON), the control is started from the
previous PID command value.
When analog input is applied to the PID command value, the following gains, biases, filters and offsets
are applicable.
