Code Description
= Number of motor poles
BAS-13 Rated Curr Enter the rated current from the motor rating plate.
BAS-14 Noload Curr
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.
BAS-16 Efficiency 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:
Purpose Function
Speed Control
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.
Pressure Control
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.
Flow Control
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.
