System Diagnostics Fault History

The drive continuously monitors system performance and can detect a variety of abnormal conditions. In 
many cases, the drive will compensate as needed to maintain continuous system operation; however, if 
there is a high risk of equipment damage, the drive will stop the system and display the fault condition. If 
possible, the drive will try to restart itself when the fault condition subsides. Each time a fault is detected in 
the system, the drive records the fault with the date and time the fault was detected. A maximum of 100 
events are recorded. Events can be viewed and retrieved with the USB device or the SubDrive Connect Plus 
mobile app.

Diagnostic Fault Codes

Code

Fault

Possible Cause

Corrective Action

F1

Motor Underload

• Over-pumped well
• Broken shaft or coupling
• Blocked screen, worn pump
• Air/gas locked pump
• SubDrive not set properly for 

pump end

• Underload Sensitivity setting 

incorrect

• Frequency near maximum with load less than configured 

underload sensitivity (SubDrive Connect Plus mobile app)

• System is drawing down to pump inlet (out of water)
• High static, light loading pump - reset Underload Sensitivity 

setting (in the programming menu and mobile app) if not out 
of water

• Check pump rotation, reconnect if necessary for proper 

rotation

• Air/gas locked pump - if possible, set deeper in well to reduce
• Verify MAX AMPS setting (in the programming menu and 

mobile app) is correct

F2

Undervoltage

• Low line voltage
• Miswired input leads
• Loose connection at breaker or 

panel

• Line voltage low, less than approximately:

- 155 VAC (normal 230 operating range = 190 to 260 VAC)
- 290 VAC (normal 460 operating range = 380 to 520 VAC)

• Check incoming power connections and correct or tighten if 

necessary

• Incorrect incoming voltage - check fuses, contact power 

company

F3

Overcurrent or

Locked Pump

• Motor and/or pump 

misalignment

• Dragging motor and/or pump
• Motor and/or pump locked
• Abrasives in pump
• Excess motor cable length

• Amperage is above MAX AMPS at 30 Hz
• Remove and repair or replace as required
• Reduce motor cable length. Adhere to Maximum Motor Cable 

Length table.

F4

Incorrectly Wired

• Input and output wires are 

swapped

• Check wiring, check motor size, adjust or repair as needed

F5

Open Phase

• Loose connection
• Defective motor or drop cable
• Wrong motor

• Open reading on DC test at start.
• Check drop cable and motor resistance, tighten output 

connections, repair or replace as necessary. 

• Use dry motor to check drive functions. If drive runs and 

exhibits an underload fault, drive is good.
