28 PowerXL DG1 Series Adjustable Frequency Drives MN040012EN—March 2014 www.eaton.com
28 Device Removed Fault Optional board removed from slot, or power
board removed from control board
Device no longer available
29 Device Unknown Fault Unknown device connected (power
board/option board
Device no longer available
30 IGBT OverTemp Fault IGBT temperature is too high • Check loading
• Check motor size
• Decrease switching frequency
31 Encoder Fault Fault • Encoder 1 channel A is missing
• Encoder 1 channel B is missing
• Both encoder 1 channels are missing
• Encoder reversed
• Encoder board missing
• Check encoder connections
• Check encoder and encoder cable
• Check encoder board
• Check encoder frequency in open loop
32 AIN<4 mA
(4 to 20 mA
Configurable
1
No Action
33 External Fault Configurable
1
Fault Digital input
34 Keypad
Communication Fault
Fault The connection between the control
keypad and frequency converter is broken
Check keypad connection and possible
keypad cable
35 FieldBus
communication Fault
Configurable
1
Fault Except communication board, also control
board can communicate with external device
using RS-485 port, so the possible cause
includes the connection between external
device and control board
Check installation and Fieldbus master
36 OPT Card Fault Configurable
1
Fault Defective option card or slot Check option card and slot
37 BypassOverLoad Fault Over load when motor is in bypass mode Check motor connection situation
38 Real time clock fault Configurable
1
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
39 PT100 Fault Configurable
1
Fault Temperature is over user set value Pt100 short, open or over temperature
40 Motor ID fault Fault The Motor ID Run was not completed
successfully
Check motor size
Motor may be not compactable with VFD
41 Current Measure
Fault
Fault Current measurement is out of range Restart the drive again. Should the fault
re-occur, contact the distributor near to you
42 Possible power
wiring error detected
Fault Reserved
43 Control Board
OverTemp
Fault Control board is over +85 degrees or under
–30 degrees
Check NTC resistor
Check control board temperature
44 Internal-ctrl Supply Fault +24V port voltage is over 27V or under 17V Check voltage range of +24V
45 Too Many Speed
Search Restarts
Fault Speed searching failed Check motor parameters’ setting
46 Current Unbalance Fault Reserved
47 Replace Battery Configurable
1
Warning Battery voltage is too low Check the battery
48 Replace Fan Configurable
1
Warning Fan life is less than 2 months Check the fan
49 Safe Torque Off Fault STO Triggered Reset STO Trigger
50 Over Current
Controller
Warning The output current has reached the current
limit value
Check the load
Set the acceleration time longer
51 Over Voltage
Controller
Warning The DC link voltage has reached its voltage
limit value
Check the input voltage
Set the acceleration/deceleration time
longer
