In this article we are going to discuss about siemens v20 vfd drive fault Cause and Remedy for this fault codes ( F80, F85, F100, F101, F221, F350, F395, F410, F452 )
F80 - FAULT: Signal lost on Analog Input
CAUSE :
- Broken wire
- Signal out of limits
F85 - FAULT: External Fault
CAUSE :
- External fault triggered via command
- input via control word 2, bit 13.
REMEDY :
- Check P2106.
- Disable control word 2 bit 13 as command source.
- Disable terminal input for fault trigger
F100 - FAULT: Watchdog Reset
CAUSE :
- Software Error
REMEDY :
- Contact service department or change inverter.
F101 - FAULT: Stack overflow
CAUSE :
- Software error or processor failure.
REMEDY :
- Contact service department or change inverter.
F221 - FAULT: PID feedback below minimum value
CAUSE :
- PID feedback below minimum value P2268.
REMEDY :
- Change value of P2268.
- Adjust feedback gain.
F222 - FAULT: PID feedback above maximum value
CAUSE :
- PID feedback above maximum value P2267.
REMEDY :
- Change value of P2267.
- Adjust feedback gain.
F350 - FAULT: Configuration vector for the inverter failed
CAUSE :
- During startup the inverter checks if the configuration vector (SZL vector) has been programmed correctly and if hardware matches the programmed vector.
- If not the inverter will trip.
- r0949 = 1: Internal failure - no hardware configuration vector available.
- r0949 = 2: Internal failure - no software configuration vector available.
- r0949 = 11: Internal failure - inverter code not supported.
- r0949 = 12: Internal failure - software vector not possible.
r0949 = 13: Wrong power module fitted.
r0949 > 1000: Internal failure - wrong I/O board fitted.
REMEDY :
- Internal failures cannot be fixed.
- r0949 = 13 - Make sure the right power module is fitted.
- Note: Fault needs power-cycle to be acknowledged.
F395 - FAULT: Acceptance test/confirmation pending
CAUSE :
- This fault occurs after a startup clone.
- It can also be caused by a faulty read from the EEPROM, see F51 for more details.
- A startup clone could have changed and might not match the application.
- This parameter set needs to be checked before the inverter can start a motor.
- r0949 = 3/4: Inverter data change
- r0949 = 5: Startup clone via an MMC/SD card has been performed
- r0949 = 10: Previous startup clone was aborted
REMEDY :
- The current parameter set needs to be checked and confirmed by clearing the fault.
F410 - FAULT: Cavitation protection failure
CAUSE :
- Conditions exist for cavitation damage.
- Cavitation damage is damage caused to a pump in pumping systems when the fluid is not flowing sufficiently.
- This can lead to heat build up and subsequent damage to the pump.
REMEDY :
- Conditions exist for cavitation damage.
- Cavitation damage is damage caused to a pump in pumping systems when the fluid is not flowing sufficiently.
- This can lead to heat build up and subsequent damage to the pump.
F452 - FAULT: Load Monitoring Trip
CAUSE :
- Load conditions on motor indicate belt failure or mechanical fault.
- r0949 = 0: trip low torque / speed
- r0949 = 1: trip high torque / speed
REMEDY :
Check the following:
- No breakage, seizure or obstruction of inverter train.
- Apply lubrication if required.
If using an external speed sensor, check the following parameters for correct function:
- P2192 (delay time for permitted deviation)
- P2182 (threshold frequency f1)
- P2183 (threshold frequency f2)
- P2184 (threshold frequency f3)
If using a specific torque / speed range, check parameters:
- P2182 (threshold frequency 1)
- P2183 (threshold frequency 2)
- P2184 (threshold frequency 3)
- P2185 (upper torque threshold 1)
- P2186 (lower torque threshold 1)
- P2187 (upper torque threshold 2)
- P2188 (lower torque threshold 2)
- P2189 (upper torque threshold 3)
- P2190 (lower torque threshold 3)
- P2192 (delay time for permitted deviation)
