23- 11 Sleep Time of Constant Pressure
Range 【0.0~255.5】Sec
When the inverter finishes counting the sleep time (23-11), the output frequency falls
downward at the deceleration time (00-15) and gets into sleep status. Parameter 23-10 (sleep
frequency of constant pressure) is dedicated by the pump and it is not applied to parameter
10-17 (start frequency of PID sleep).

23- 12 Maximum Pressure Limit
Range 【0.00 ~ 650.00】PSI
It is convenient for user to limit maximum pressure. When pressure feedback value is higher
than maximum pressure limit, the inverter displays warning signal and then stops.
23- 15 Minimum Pressure Limit
Range 【0.00 ~ 650.00】PSI
It is convenient for user to limit minimum pressure. When pressure feedback value is lower than
minimum pressure limit, the inverter displays warning signal and then stops.
Fig. 4.3.104 Diagram for pressure feedback limit
Note:
The pressure under the control of PID is between the maximum pressure limit (23-12) and minimum
pressure limit (23-15).
