Appendix A—Fault and Warning Codes
42 PowerXL DH1 Series Variable Frequency Drives MN040039EN—April 2018 www.eaton.com
36 Compatibility Fault Fault The control board isn’t matched with the
power board.
Cycle power to drive. Try updating
software. If issue continues, contact
distributor near you.
37 Device Change Warning Power board or option card change. Alarm will reset
38 Device Added Warning Power board or option board added. Device is ready for use
Old parameter settings will be used
39 Device Removed Fault Optional board removed from slot, or power
board removed from control board.
Device no longer available in drive.
40 Device Unknown Fault Unknown device connected (power board/
option board)
Check EEPROM connection.
Check board connection on slot A/B
Power cycle to drive.
41 IGBT Over Temp Fault IGBT temperature is too high. • Check output loading
• Check motor size
• Decrease switching frequency
50 AI < 4mA (4to20mA) Configurable No Action Loss in analog input signal, dropped below
4mA.
Verify analog input current reference value
on either AI1 or AI2, check cabling.
51 External Fault Configurable Fault Digital input is activated for external fault
input.
Check digital input settings and verify input
level, could be an external device causing
fault.
52 Keypad Comm Fault Configurable Fault The connection between the control keypad
and frequency converter is broken when the
local reference is keypad or the local control
place is keypad.
Check keypad connection and possible
keypad cable.
54 Option Card Fault Configurable Fault Defective option card or option card slot Check right option card and option card
slot connections.
Check Board Status on Keypad for exact
cause of fault.
Contact distributor nearest you.
55 Realtime Clock Fault Configurable Warning • Communication between MCU and RTC
chip isn’t normal
• The power of RTC chip isn’t normal
• The real time isn’t normal
Check the RTC chip, power cycle to drive. If
issue continues, contact distributor near
you.
56 PT100 Fault Configurable Fault Temperature is beyond the limit of sensing
capacity of PT100
PT100 short, open or over temperature,
check PT100 temperature probe.
57 Motor ID fault Fault The Motor parameters Identification running
was not completed successfully
Check motor size
Verify the input and output wiring is
connected properly.
58 Current Measure
Fault
Fault Current measurement is out of range Restart the drive again. Should the fault
re-occur, contact the distributor near you
59 Power Wiring Error Fault Power wiring connected to output of drive. Verify power input wiring is connected to
L1, L2 and L3 terminals and that they are
properly torqued.
60 Control Board
OverTemp
Fault Control board is over +85 degrees or under
–30 degrees
Check NTC resistor
Check control board temperature
61 Internal Control
Supply
Fault +24V port voltage is over 27V or under 17V Check voltage range of +24V on terminals
12 to 13. If voltage is out of range, contact
distributor near you.
62 Speed Search Fault Fault Speed searching failed when performing
flying start.
Check motor parameters’ setting and
mo
tor connectio
ns.
64 Replace Battery Configurable Warning RTC battery voltage is too low. Check the RTC battery voltage, contact
distributor near you for replacement
battery.
