5.9 External PID
External PID refers to the PID features other than the basic PID features required to control
the inverter. The following table shows the areas where external PID controls can be
applied.
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 amount of flow in the equipment or
machinery to be controlled. Control maintains consistent flow or
operates at a target flow.
Temperature
Control
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.
Depending on the PID output mode, the EPID output value can be overlapped to the PID
output. External output is also available through the analog output settings at OUT-01 and
OUT-07.
