Toshiba TOSVERT VF-PS1 Instruction Manual page 5

4) Set the following parameter to suit the system.
a) Set the acceleration time and deceleration time to small for quick response.
But too small setting cause inverter trip.

b) 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.
a) Fundamental adjustment
Item
PID control gain
b) Adjust the following parameters if necessary.
Deviation means difference between process value and feedback value.
Item
Steady the PID control.
(Limit the PID deviation)
Start the PID control after
the system become stable.
Acceleration time 1
Deceleration time 1
