When using analog feedback, this function code can set the setting value of closed-loop control through using the
operation panel. But this function is valid only when the digital setting channel of closed-loop is selected (08.01 is 0).
For example, in the closed-loop control system of constant pressure water supply, the setting of this function code
should fully consider the counting relationship between the range of the remote pressure gauge and its output feedback
signal. For example, the range of the pressure gauge is 0 ~ 10 MPa, which corresponds to the output voltage of 0 ~ 10 V,
and we need 6 MPa pressure, so we can set the digital value into 6.00V, so when the PID regulation is stable, the required
pressure is 6 MPa.

The feedback value of PID is determined by the difference between AI1 and AI2. When the difference is negative, the

LED bit: PID regulation characteristics
0: positive effect
When the feedback signal is higher than the set value of PID, the output frequency of the inverter is required to
decrease (means that the feedback signal is reduced), so that the PID can reach the balance. All that means a positive
characteristic. Such as using for tension control of winding machine and constant pressure water supply control.
1: negative effect
When the feedback signal is higher than the set value of PID, the output frequency of inverter is required to rise (that is,
the feedback signal is reduced), so that the PID can reach balance. All that means a negative characteristic. Such as
tension control of winding machine and central air conditioning control.
LED bit: Proportional-integral control characteristics (reservation)
0: constant proportional-integral control
1: automatic proportional-integral control
LED hundred-digit: integral control characteristic
0: stop integral adjustment when the frequency reaches the upper and lower limits
1: when the frequency reaches the upper and lower limits, continue the integral adjustment
For systems requiring rapid response, it is recommended to cancel the continuous integral adjustment
