2. PID Control I Integral Time (J04)
In this operation, the operation amount is proportional to the time integral value of the deviation.
The P operation is less effective as the current value approaches the target value due to smaller
deviation, taking a long time to reach the target value. The I operation compensates this disadvant-
age.
3. PID Control D Differential Time (J05)
In this operation, the operation amount is proportional to the percentage of change in the deviation.
Because using only the PI operation is time-consuming, the D operation is used to effectively com-
pensate for the disadvantage in responsiveness.
PID Normal Operation/Reverse Operation
Since normal operation or reverse operation can be selected for the output of PID process control, the
fluctuations in the motor rotation speed with respect to the deviation (difference between the command
value and feedback value) can be set. Switching of normal operation and reverse operation by an ex-
ternal signal (21:IVS (Switch normal/inverse operation)) is also possible.
PID command
This command is used to select the means for setting the command values of PID control.
