Applied Adjustment (Common); Pid Deviation Upper Limit And Lower Limit; Pid Differentiation / Integration Reset; Pid Control Waiting Time - Toshiba TOSVERT VF-PS1 Instruction Manual

5.3. Applied adjustment (Common)

Adjust the following for stability if necessary.

5.3.1. PID deviation upper limit and lower limit

Limit the PID deviation momentarily for stability. (It is not necessary to change under normal conditions.)
Inverter can output the signal in case of the deviation level within the limit setting.

5.3.3. PID control waiting time

You can set the waiting time before PID control start.
It is useful in case the system is not steady at start, etc.
Title
f369
PID control waiting time
Function
It is upper limit of deviation increase (+).
It is lower limit of deviation decrease (-).
Function
In case of the PID deviation level between f364
and f365.
Function
Reset the PID differentiation value and integration
value.
Function
Inverter operates with frequnency reference setted by
process value within f369 setting time.
After f369 setting time, switch the PID control mode.
