23- 17 Fault Stop Time of Low Pressure
Range 【0.0 ~ 600.0】Sec
When the warning signal of low pressure occurs and pressure feedback value is lower than
minimum pressure limit, stop time of low pressure starts to count. If pressure feedback value is
higher than minimum pressure limit during counting time, the stop time will recount and the
inverter will display stop error signal of LPbFt when the stop time ends.
Fig. 4.3.106 Diagram for warning to stop at low pressure limit
Note:
When user does not want the inverter to be restricted by the minimum pressure, set 23-75=0
(disable) to disable the function of low pressure limit.
23- 18 Time of Loss Pressure Detection
Range 【0.0 ~ 600.0】Sec
23- 19 Proportion of Loss Pressure Detection
Range 【0 ~ 100.0】%
When 23-19 = 0 or 23-78 = 0, function of loss pressure detection is disabled.
When 23-19 > 0, If the feedback pressure value is lower than the value of 【(23-02) x (23-19)】
and the detection time of loss pressure (23-18) passes, the inverter jumps to fault signal
(FBLSS).
23- 22 Slave Trip Frequency
Range 【0.0~599.0】Hz
If Master and Slave start to run at the same time, Slave will stop depend on the condition listed as
below:
(1) When 23-22=0 Hz, if output frequency of Slave is lower than 23-10 (Sleep Frequency of
constant Pressure) and after the time of 23-11 (Sleep Time of Constant Pressure), the Slave will
be stop automatically.。
(2) When 23-22 = 1~599 Hz (The maximum frequency follow 01-02), if the output frequency of
slave is lower than 23-22, Master will inform Slave to stop and enter sleep mode, or output
frequency of Slave is lower than 23-10 (Sleep Frequency of Constant Pressure) and after the
time of 23-11 (Sleep Time of Constant Pressure), the Slave will be stop automatically.。
