PID output upper limit

Setting range: 0.0-100.0%

F11.23

PID output lower limit

Setting range: -100.0-F11.19

F11.24

PID output filter time

Setting range: 0.000-6.000s

[F11.22 ] is used to set the PID output upper limit;[F11.23] sets the PID output lower limit.

[F11.24] PID output filter time used to filter the PID output.It will weak the surge caused by PID output result, and

decrease the closed-loop system response performance.

F11.25

Detection time while feedback wire break

F11.26

Act selections while feedback wire break

F11.27

Wire break alarm upper limit

F11.28

Wire break alarm lowest limit

While PID given frequency and inverter is running, if feedback signal which is bigger the [F11.27] or smaller than

[F11.28] is detected out and keeps for [F11.25] delay time, it is considered as sensor wire break.

Feedback wire-break action selections

0: Go on PID operation without alarm: no wire-break detection when invalid

1: Stop and alarm malfunction: When the inverter detects a sensor break, immediately block output, motor free

stop and report E.PID fault.

2: Go on PID operation and output alarm signal: When the inverter detects a sensor break, still run by the PID

regulation, but the keyboard displays E.PID fault and flashes.

3: Run the current frequency and output alarm signal: When the inverter detects a sensor break, maintain

constant output frequency before the fault, but the keyboard displays E.PID fault and flashes.

Wire break alarm upper limit:

Set the upper limit of PID sensor wire break detection.When feedback signal is over alarm upper limit for time

[F11.25], it is considered as sensor wire break.

Wire break alarm lower limit:

Set the lower limit of PID sensor wire break detection.When feedback signal is under alarm upper limit for time

[F11.25], it is considered as sensor wire break.

Sleep into the judgment:

When the constant pressure water supply sleep function is valid, when the PID adjustment output frequency is lower

than the set [F11.30] sleep frequency, it will enter the sleep state after the [F11.31] sleep delay (ie, the output will be

blocked after deceleration to zero frequency).

Sleep wakeup judgment:

When the PID feedback characteristic is positive:

The PID reference (C00.08) minus the wake-up deviation (F11.32) is compared with the PID feedback (C00.09). If it

continues to be greater than the wake-up delay [F11.33], it exits the sleep state and enters the normal operating status.

When the PID feedback characteristic is inverse characteristic:

The PID reference (C00.08) plus the wake-up deviation (F11.32) is compared with the PID feedback (C00.09). If it

continues to be greater than the wake-up delay [F11.33, exit the sleep state and enter the normal running state.
