F13.24
PID output filtering
(0x0D18)
time
RUN
The PID output filter time is used to filter the PID output, which will attenuate the sudden change of the PID regulation output and bring about a decrease
in the response performance of the process closed-loop system.
F13.25-F13.28: PID feedback disconnection judgment
The feedback disconnection detection function is defined as when the drive reference mode is selected as PID timing, and when the drive is running, when
the detected feedback signal is greater than the set value of [F13.27] or less than [F13.28] The sensor is disconnected after setting the value and
maintaining the delay time of [F13.26].

Feedback disconnection action selection:
0: Continue PID operation without reporting fault
1: Stop and output fault alarm E.PID
to stop and alarm E.PID.
2: Continue PID operation, output fault warning A.PID
operation, but the keyboard displays the warning A.PID.
3: Run at the current frequency, output fault warning A.PID
the fault remains unchanged, but the keyboard displays the warning A.PID.

Broken line alarm upper limit:
Set the upper limit of the PID sensor disconnection detection. When the feedback signal exceeds the upper limit of the disconnection alarm and continues
the delay time of [F13.26], the sensor is considered to be disconnected.
Broken line alarm upper limit:
Set the lower limit of the PID sensor disconnection detection. If the feedback signal is less than the lower limit of the disconnection alarm and continues
the delay time of [F13.26], the sensor is considered to be disconnected.
F13.29-F13.33: Sleep function
The PID sleep function can be used in the constant pressure water supply industry to achieve energy saving goals.
Sleep into the judgment:
When the sleep function is valid, when the PID adjustment output frequency is lower than the set [F13.30] sleep frequency, it will enter the sleep state after
the [F13.31] sleep delay (ie, the output will be blocked after deceleration to zero frequency).
Note: Sleep enters the precondition. When the PID feedback is greater than the PID given when the positive characteristic is triggered, the PID feedback
is triggered only when the PID feedback is less than the PID given.
Sleep wakeup judgment:
When the PID feedback characteristic is positive characteristic: the value of PID given minus the wake-up deviation [F13.32] is compared with the PID
feedback. If it continues to be greater than the wake-up delay [F13.33], it will exit the sleep state and enter the normal running state.
When the PID feedback characteristic is inverse characteristic: the value of PID given plus wake-up deviation [F13.32] is compared with the PID feedback.
If it continues to be greater than the wake-up delay [F13.33], it will exit the sleep state and enter the normal running state.
