4) Set the following parameters to suit the system.
Speed PID control set the acceleration time and the deceleration time to the smallest automatically in
spite of parameter(acc,dec) setting.
The quick response is enabled by process increase and decrease rate separated from acceleration
time and declereation time.
Set the following parameters if necessary.
Item
Limit the input level of
process value.
Limit the PID output.
Switc the PID forward
/reverse characteristic.
Output of agreement signal
between process value
and feedback value.
<VF-PS1 only>
5) Adjust the PID control gain.
See the section 5 for detail.
a) Fundamental adjustment
And adjust for stability and quick response.
Deviation means difference between process value and feedback value.
Item
PID control gain
Steady the PID control
(Feedback filter)
Steady the PID control.
(Limit the PID deviation)
Adjust for quick responce
b) Adjust the following parameters if necessary.
Item
Start the PID control after
the system become stable.
Jump frequency 1 to 3
Operation starting frequency
Operation starting frequency hysteresis
Stop frequency setting
