You can only convert PID2 output to analog signal by setting the AO function (setting 32).
For details about related function codes, see function code groups P90 and P91.
5.5.18 Segmented water pressure
After the clock function is enabled, you can set working days through P92.04 and set start time and
stop time of working days through P92.05–P92.08. P95 can specify water pressure by time segment.
Within a specific time segment, the PID reference source is switched to the water pressure
corresponding to the time segment.
Note: To use this function, you need to purchase the option part—LCD keypad (model: SOP-270) and
prepare the button battery.
For details about related function codes, see function code group P92.
5.5.19 Automatic sleep
Function code P94.01 specifies the sleep method. When the condition specified by P94.02 or P94.03
and the condition lasts the time specified by P94.04, the PID increases by P94.05 (PID boost value
for sleep) with a duration specified by P94.06 (PID boost time), and the VFD enters the sleep state.
When P94.08 (Wakeup condition) is met and this condition lasts the time specified by P94.09
(Wakeup time), the VFD automatically wakes up from sleep and directly runs at the frequency
specified by P94.07, and the frequency is PID regulated later.

When output is positive, if the feedback is
greater than the reference, sleep is allowed
only when the absolute difference is greater
than the value of this function code and the
situation lasts the time longer than P94.04.
When output is negative, if the feedback is
less than the reference, sleep is allowed only
