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.

2.2.Speed PID control
Speed PID control is selected for speed control of a winder to which fast response is required.
Acceleration/ deceleration time is automatically set to the shortest time. It also responds much faster by
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 
