These parameters are used to implement the dormant and wakeup functions in the water supply
application.
When the inverter is in running state, the inverter enters the dormant state and stops automatically after
the dormant delay time (F4.52) if the set frequency is lower than or equal to the dormant frequency (F4.51).
When the inverter is in dormant state and the current running command is effective, the inverters starts
up after the wakeup delay time (F4.50) if the set frequency is higher than or equal to the wakeup frequency
(F4.49).
Generally, set the wakeup frequency equal to or higher than the dormant frequency. If the wakeup
frequency and dormant frequency are set to 0, the dormant and wakeup functions are disabled.
When the dormant function is enabled, if the frequency source is PID, whether PID operation is
performed in the dormant state is determined by FA.28. In this case, select PID operation enabled in the stop
state (FA.28 = 1).
F4.53 Current running time reached
If the current running time reaches the value set in this parameter, the corresponding output terminal
becomes ON, indicating that the current running time is reached.
F4.54 ADT1channel selection
F4.55 ADT2channel selection
F4.56 ADT1 output upper limit
F4.57 ADT1 output lower limit
F4.58 ADT2 output upper limit
F4.59 ADT2 output lower limit
When the AI voltage is higher than the ADT upper limit value, the inverter function output terminal
(41/42: Frequency detection ADT1 / ADT2 output) will be ON , and the frequency is below the lower limit
value of ADT, the ON signal is canceled.
Group F5: Vector Control Parameters
F5.00 Speed loop proportional gain 1
F5.01 Speed loop integral time 1
F5.02 Switchover frequency 1
F5.03 Speed loop proportional gain 2
F5.04 Speed loop integral time 2
F5.05 Switchover frequency 2
F5-00 to F5-05 are speed loop PI parameters.
● If running frequency ≤ F5-02 (Switchover frequency 1), PI parameters are F5-00 and F5-01.
● If running frequency ≥ F5-05 (Switchover frequency 2), PI parameters are F5-03 and F5-04.
● If running frequency is between F5-02 and F5-05, PI parameters are obtained from linear
switchover between two groups of PI parameters, as shown in Figure.
