System Diagnostic Fault History
The SubDrive Connect 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 opera-
tion; 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 de-
tected. A maximum of 500 events are recorded and can be viewed and emailed using the FE Connect
mobile app.

Possible Causes
• High static, light loading pump
• Over-pumped well
• Broken shaft or coupling
• Blocked screen, worn pump
• Air/gas locked pump
• SubDrive not set properly for pump end
• Frequency near maximum with load less
than configured underload sensitivity
• System is drawing down to pump inlet
(out of water)
• Maximum frequency set too low for per-
manent magnet motor
• Low line voltage, less than approxi-
mately 150 VAC
• Miswired input leads
• Loose connection at breaker or panel
• Motor and/or pump misalignment
• Dragging motor and/or pump
• Motor and/or pump locked
• Abrasives in pump
• Excess motor cable length
• Amperage above SFL at 30 Hz
• Incorrect motor type selected
• Wrong resistance values on main and
start
• Loose connection
• Defective motor or drop cable
• Wrong motor
Corrective Action
• Reset Potentiometer for less sensitivity if not out of
water
• Check pump rotation, reconnect if necessary for
proper rotation
• If possible, set deeper in well to reduce possibility of
air/gas locked pump
• Verify DIP switches are set properly
• Check Underload Sensitivity Setting (Potentiometer
or Wi-Fi)
• Increase maximum frequency to 125Hz or more for
permanent magnet motors - if maximum frequency
must be below 125Hz, adjust underload sensitivity
setting to a lower value.
• Line voltage needs to be 190 to 260 VAC
• Check incoming power connections and correct or
tighten if necessary
• Correct incoming voltage. Check circuit breaker or
fuses, contact power company
• Remove and repair or replace as required
• Reduce motor cable length. Adhere to Maximum
Motor Cable Length table.
• Confirm the motor type on DIP SW1 Position 7 is set
correctly.
• Check wiring, motor size and DIP switch setting. Ad-
just or repair as needed
• Open reading on DC test at start.
• Check drop cable and motor resistance, tighten out-
put connections, and repair or replace as necessary.
• Use dry motor to check drive functions. If drive runs
and exhibits an underload fault, drive is good.
