POWERXL DM1 SERIES VARIABLE FREQUENCY DRIVE MN040049EN—September 2021 www.eaton.com
Default
configuration Possible cause
Configurable Motor is too hot, based on either the drive's estimate or on
temperature feedback.
Configurable Condition defined by parameter underload protection,
underload Fnom
the time defined by underload time limit.
Configurable IP setting issue.
Power board EEPROM fault, memory lost in EEPROM.
EEPROM data error in EEPROM memory.
Serial flash error; serial flash memory failed.
Estimated speed is greater than 115% of maximum frequency.
Or current loop is oscillating.
STO switch is broken; STO circuit failure.
Watchdog register overflows in MCU.
The time when interlock signal activates is over setting time.
Power board or option card change.
Power board or option board added.
Optional board removed from slot; or power board removed
from control board.
Unknown device connected (power board/option board).
IGBT temperature is too high.
Configurable Loss in analog input signal, dropped below 4 mA.
Configurable Digital input is activated for external fault input.
Configurable The connection between the control keypad and frequency
converter is broken, and the local reference is keypad
reference or the local control place is keypad, and the keypad
communication fault protection is not "NO action"
Configurable Defective option card or option card slot.
The motor parameters identification running was not
completed successfully.
Current measurement is out of range.
Configurable STO triggered; STO input is open.
The output current has reached the current limit value.
torque, underload F0 torque, valid longer than
Remedy
Decrease motor load. If no motor
overload exists, check the temperature
model parameters.
Check load.
Check settings for IP address. Verify no
duplicates are on the network.
Cycle power to drive. Try updating
software. If issue continues, contact
distributor near you.
Cycle power to drive. Try updating
software. If issue continues, contact a
distributor near you.
Cycle power to drive. Try updating
software. If issue continues, contact a
distributor near you.
Check motor parameters and run
identification. Adjust the Observer Kp.
Check STO switch and STO circuit. If
issue continues, contact a distributor
near you.
Cycle power to drive. Try updating
software. If issue continues, contact a
distributor near you.
Stop drive and resend start command.
Alarm will reset.
Device is ready for use. Old parameter
settings will be used.
Device no longer available in drive.
Check EEPROM connection.
Check board connection on slot A/B.
Power cycle to drive..
• Check output loading.
• Check motor size.
• Decrease switching frequency.
Verify analog input current reference
value on either AI1 or AI2, check cabling.
Check digital input settings and verify
input level, could be an external device
causing fault.
Check keypad connection and possible
keypad cable.
Check right option card and option card
slot connections.
Check board status on keypad for exact
cause of fault.
Contact distributor nearest you.
Check motor size.
Verify the input and output wiring is
connected properly.
Restart the drive again. Should the fault
re-occur, contact the distributor nearest
to you.
Reset STO trigger and verify wiring.
Reset fault after input is enabled.
Check the load.
Set the acceleration time longer.
