Pid2 Control - Toshiba TOSVERT VF-AS3 Instruction Manual

PID2 control

The PID2 control has two types of PID control blocks internally, and they can be switched by the setting of [A300: PID1,2
switching target].
For example, you can perform the PID control for pressure in the normal situation, and the PID control for temperature
under certain conditions.
In this case, the set values and feedback values for the pressure PID control and temperature PID control need to be
input.
■ Diagram
Diagram of PID2 control is same as 2.1 to 2.4. Refer to chapter 8 for parameter.
■ Parameter setting
1) Select PID control type.
PID control types of PID2 are same as PID1 control, but polarity is selectable by [A310].
Example: When you select process type for PID1, PID2 is also process type PID control.
