What to do if FE PXR4 Microcontrollers are not controlling properly?
- C
  Carlos WallerAug 20, 2025
  If your FE Microcontroller isn't controlling properly, it might be because the set values of the parameters P and are incorrect; try performing the auto-tuning. If the cycle times are too long, decrease the set value of the parameters and gradually. If the output is limited, set the parameters of, and again to be suitable for the process. If the output is not limited correctly, set the parameters of again to be suitable for the process.

Why is auto-tuning not working on my FE PXR4 Microcontrollers?
- A
  Austin ClarkAug 23, 2025
  If auto-tuning isn't working properly on your FE Microcontroller, it could be due to several reasons. If the display shows or after starting the auto-tuning operation, set the parameters again so that the difference of the set values of and is made larger, and then perform the auto-tuning again. If you changed the SV after starting auto-tuning, set the desired SV and repeat the auto-tuning. Also, if you attempted auto-tuning during ramp-soak operation, set the parameter to and try again. Ensure that peripheral devices are properly connected. If the response of the controlled device was too fast, use a controller whose control cycle is fast, such as PYH.

How to fix SV if it cannot be changed on FE PXR4 Microcontrollers?
- T
  tavilaAug 26, 2025
  If the SV on your FE Microcontroller cannot be changed, it might be because is set to “1” or “4” in the parameter; set the parameter to “0”, “2”, “3” or “5”. Another reason could be that you're trying to set a value outside the SV limiter; widen the range of to , ensuring it remains within the set range in the input range table.

What to do if ON/OFF control has not functioned properly on FE PXR4 Microcontrollers?
- J
  jamesbrownAug 27, 2025
  If the ON/OFF control on your FE Microcontroller isn't functioning properly, it could be because the set value of parameter is not correct; adjust the set value of parameter to be suitable for the device to be controlled. Alternatively, the setting of parameter might be incorrect; set the parameter correctly.

Why are parameters not displayed on my FE PXR4?
- L
  lisa83Aug 30, 2025
  If the parameters you wish to confirm or change are not displayed on your FE Microcontroller, it might be because the concerned parameters are set to skip in the parameters of to . To resolve this, change the set value of the concerned dSP.

Why is the response too slow on my FE PXR4 Microcontrollers?
- F
  Frederick MoralesSep 1, 2025
  If the response of your FE Microcontroller is too slow, meaning the measured value changes slowly, the input filter constant might be too large. Try decreasing the set value of the parameter .

What to do if keys do not operate on FE PXR4?
- V
  Vanessa WilliamsSep 4, 2025
  If the keys on your FE Microcontroller do not operate and you cannot change the set value of the parameters, it might be because “1”, “2”, “4”, or “5” is set in the parameter . To fix this, set the parameter to “0” or “3”.

Why are SV or parameters changing on FE Microcontrollers without operation?
- J
  Joseph SweeneySep 6, 2025
  If the SV or set values of some parameters on your FE Microcontroller have changed without any operation, it could be because the parameter was changed. To resolve this, set all the parameters again. Also, if the set value of is larger than 1000, set to “0” and return to an original value.

What to do if an excessive over-shoot occurs during auto-tuning on FE PXR4?
- D
  David GallegosSep 9, 2025
  If an excessive over-shoot has occurred during auto-tuning operation on your FE Microcontroller: (1) Perform the auto-tuning with the parameter of being “2” (Low PV type). (2) Perform the tuning manually.

What to do if ON/OFF control has not started on FE PXR4?
- N
  nguyenjesseSep 12, 2025
  If ON/OFF control (Two-position control) has not started on your FE Microcontroller, ensure that 0.0 is set in the parameter . If not, set the parameter to 0.0.
