„ Slow flowrate stop function (Cancel deviation level 1) (J158, J258)
Set a cancel deviation level to be used as a cancel condition. Set PID control 1 and PID
control 2 with function codes J158 and J258 respectively.
- Data setting range: 0.01 to 9990.00, OFF
„ Slow flowrate stop function (Cancel delay timer) (J159, J259)
Set time delay from satisfaction of slow flowrate's cancel conditions (J157, J257) until
initiation of the inverter. Set PID control 1 and PID control 2 with function codes J159 and
J259 respectively.
- Data setting range: 0 to 3600 (s)
„ Slow flowrate stop function (Cancel deviation level 2) (J160, J260)
In a case where water supply is needed until the initiation inhibition time (J156, J256) elapses,
set a cancel deviation level as a cancel (initiation) condition for water stoppage prevention.
Set PID control 1 and PID control 2 with function codes J160 and J260 respectively.
Set a value so that the following is resulted: cancel deviation level 1 (J158, J258) < cancel
deviation level 2 (J160, J260).
If a value is set so that the cancel deviation level 1 (J158, J258) exceeds the cancel deviation
level 2 (J160, J260), the cancel deviation level 2 (J160, J260) is used as the cancel condition
even when the initiation inhibition time (J156, J256) elapses.
- Data setting range: 0.01 to 9990.00, OFF
„ Assignment of PID-STP ("Motor stopped due to slow flowrate under PID control")
(function codes E20 to E24 and E27, data = 44)
With respect to PID slow flowrate stop, ON signals are output when the inverter stops due to
the slow flowrate during PID control. When signals which indicate inverter stop status are
needed, PID-STP has to be assigned.
