Troubleshooting
104
Damper Fault (DPR) • Damper limit switch has not
closed in time to start fan motor;
or, switch has opened for more
than 2 seconds while motor is
running.
• Check limit switch connections and function
• Check damper relay connections and damper function
• Verify all damper related parameters
Dec Energy Back (dEb) • Deceleration energy backup
error. When ADV2-28 is not
disabled and power is off or
momentarily off, VFD will display
dEb during accel./decel. stop.
• Check if input power is stable
Derating Error (oL3) • The VFD detects excessive drive
output current.
• Check if the motor is overloaded.
EEPROM read err (cF2) • Internal memory cannot be read. • Press “RESET” key
• Reset all parameters to default
• If error still exists, please call Technical Support..
EEPROM write err (cF1) • Internal memory cannot be
programmed.
• Press “RESET” key
• Reset all parameters to default
• If error still exists, please call Technical Support.
Emergency stop (EF1) • Emergency stop • When a multi-function input terminal (MI1 to MI6) is set to
emergency stop and the contact is closed, the AC motor drive stops
output U, V, W and the motor coasts to stop.
• Press RESET after condition has been corrected.
External Fault (EF) • External Fault • Input EF (N.O.) on external terminal is closed to GND. Output U, V, W
will be turned off.
• Give RESET command after fault has been cleared.
Ground fault (GFF) • Output current exceeds [PROT-
34] for more than [PROT-35]
time delay.
NOTE:
This protection is provided
for VFD, not to protect user.
• Check the wiring connections between the VFD and motor for
possible short circuits, also to ground.
• Check for possible poor insulation at the output.
• Verify grounding of communication circuit
• Ensure separation of communication circuits and high-voltage wiring
• Check whether the IGBT power module is damaged.
Guarding T-out (CGdE) • CANopen guarding error. When
CANopen Node Guarding detects
that one of the slaves does not
respond.
• Increase guarding time and detection times.
• Verify wiring and grounding of communication circuit.
• Make sure communication circuit is wired in series.
• Use CANopen cable or add terminating resistance.
Heartbeat T-out (CHbE) • CANopen heartbeat error. When
CANopen Heartbeat detects that
one of the slaves does not
respond.
• Increase heartbeat time
• Verify wiring and grounding of communication circuit.
• Make sure communication circuit is wired in series.
• Use CANopen cable or add terminating resistance.
Heat Sink oH (oH2) • Capacitance temperature causes
heatsink overheating.
• Ensure that the ambient temperature falls within the specified
temperature range.
• Make sure heat sink is not obstructed. Check if the fan is operating
• Check if there is enough ventilation clearance for the drive.
High Load (HLD) • Current or Torque is above [SET-
48] HLD Level and [SET-49] HLD
Frequency.
• Refer to “High Load Detection” on page 75 .
Ias sensor Err (cd1) • U-phase output error • Cycle the power. If error still exists, please call Technical support.
Ibs sensor Err (cd2) • V-phase output error • Cycle the power. If error still exists, please call Technical support.
Ics sensor Err (cd3) • W-phase output error • Cycle the power. If error still exists, please call Technical support.
