1. Introduction

VF-S15 has two types of PID control function.

You can select the type for your application.

Process PID control: The control is performed gently in response to change in temperature or

pressure for fan and pump.

Speed PID control : The control is performed at high speed in response to change in speed for

winder.

This manual is constructed as follows;

Chapter 2: Explanation of two types of PID control

Chapter 3: Parameter list for PID control

Chapter 4: Setting parameter for PID control

Chapter 5: Adjustment for PID control

Chapter 6: Analog input characteristics

It is necessary to convert process value and feedback value into frequency for setting.

controlling with the increase/ decrease rate which is separated from acceleration/ deceleration time.

Delay filter is set to the feedback value for the stable operation.

You need to convert the process value and the feedback value into frequency for the PID control.

f702 (Frequency free unit display magnification) and f703 (Frequency free unit coverage

selection) enable to set process value and feedback value easily. The functions convert frequency display

to temperature or pressure level by calculation.

Value displayed = Frequency displayed on the monitor or specified with a parameter × 

f703 = 0

Frequency on the monitor or specified with parameter is displayed by the value multiplied by .

Note) This setting does not change automatically if you switch from PID control to frequency

command operation. Output frequency is displayed by the value by .

f703 = 1

Frequency of the following parameters and the frequency on the monitor are displayed by the value

multiplied by 
