LSIS sv-ip5a - APP-71: Pressure Difference for Aux Motor Stop; APP-74, 75, 76: Pre PID Operation (Freq. Exit, Delay); APP-80~97: External PID Operation

APP-71: Pressure Difference for Aux Motor Stop
It sets the pressure difference between when Aux
motors are ON and Aux motor starting frequency.
APP-74, 75, 76: Pre PID Operation (Freq. Exit,
Delay)
Pre PID operation is a new function for smooth PID
operation. For example, before pump operation is
started, Pre PID fills water in the pump and pipe. Or
Accel/Decel operation is performed before coil
winding machine’s speed reaches a certain level.
 APP-74 [Frequency before PID operation
begins]
It is the inverter target frequency to be output until
Pre PID operation is finished when Inverter Run
signal is ON and Pre PID operation is selected.
 APP-75 [condition to activate PID operation]
User sets the value which is considered enough to
start PID operation compared to feedback value
during Pre PID operation. If the feedback value
exceeds the set value in APP-75, Pre PID operation
ends and PID operation begins.
 APP-76 [Pre PID delay time]
When feedback value is less than APP-75 value even
though time set in APP-76 elapses, inverter signals
system malfunction. It is also user-settable to fit for
the system in use.
