Enter the rated current from the motor rating plate.
Enter the measured current when the load on the motor axis is removed
and when the motor is operated at the rated frequency. If no-load current
is difficult to measure, enter a current equivalent to 30-50% of the rated
motor current.
Enter the efficiency from the motor rating place.
5.8 PID Control
PID control is one of the most common auto-control methods. It uses a combination of
proportional, integral, and differential (PID) controls that provide more effective control for
automated systems. The functions of PID control that can be applied to the inverter
operation are as follows:
Controls speed by monitoring the current speed levels of the
equipment or machinery being controlled. Control maintains
consistent speed or operates at the target speed.
Controls pressure by monitoring the current pressure levels of
the equipment or machinery being controlled. Control maintains
consistent pressure or operates at the target pressure.
Controls flow by monitoring the current amount of flow in the
equipment or machinery being controlled. Control maintains
consistent flow or operates at a target flow.
Controls temperature by monitoring the current temperature
levels of the equipment or machinery to be controlled. Control
maintains a consistent temperature or operates at a target
temperature.
