Fault Display and Corrective Actions at Auto-Tuning
The following are fault displays and corrective actions at auto-tuning. If any of the following faults are
found, the digital operator displays that fault contents; the motor coasts to stop if it is under
operation. Fault contact output or minor fault contact output does not operate.
Table 6-5: Fault Display and Corrective Actions
Fault Display Fault or Indicator Name/Description Corrective Action
Er-01
Fault
Motor Data Fault. Motor data input fault for
auto-tuning. Relationship between motor
output and motor rated current fault.
Relationship between input motor rated
current and set no-load current fault (at vector
control method and line-to-line resistance
tuning.)
• Check input data.
• Check inverter and motor capacity
• Check motor rated current and no-load
current.
Er-02
Minor Fault
Alarm. The minor fault is detected during
auto-tuning.
• Check input data.
• Check wirings
• Check load.
Er-03
STOP Key
STOP Key Input. The stop key is pressed
during auto-tuning.
Er-04
Resistance
Line to Line Resistance Fault. Auto-tuning
is not completed within the expected time.
The auto-tuning is outside the parameter
setting.
• Check input data.
• Check motor wiring.
• If a motor and a load are connected,
disconnect the motor from machinery
system.
Er-05
No-Load Current
No-load Current Fault. Auto-tuning is not
completed within the expected time. The
auto-tuning is outside the parameter setting.
Er-08
Rated Slip
Rated Slip Fault. Auto-tuning is not
completed within the expected time. The
auto-tuning is outside the parameter setting.
Er-09
Accelerate
Acceleration Fault. The motor did not
accelerate at the expected time.
• Increase B05-01 (acceleration time).
• If C07-01 and C07-02 (torque limit value)
are decreased, increase values.
• If a motor and a load are connected,
separate the motor from the load.
Er-10
Motor Direction
Motor Direction Error. The encoder signal
lines are not properly connected to the drive;
the motor direction and PG direction are
opposite; or the load pulled the motor in the
opposite direction of the speed reference and
the torque exceeded 100%.
• Check and correct wiring to the PG
encoder.
• Check the motor speed monitor U01-05
while manually turning the motor forward. If
the sign displayed is negative, change the
setting of parameter F01-02.
• Uncouple the motor from the load and
restart Auto-Tuning.
Er-11
Motor Speed
Motor Speed Fault (Rotation type tuning
only).
The motor speed was over 100% at auto-
tuning (flux vector control without PG only).
• Increase B05-01 (acceleration time).
• If a motor and a load are connected,
separate the motor from the load.
Er-12
I.det.Circuit
Current Detection Fault. Current exceeded
the motor rated current.
• Release brake.
• Check for open motor lead.
Er-13
Leakage
Inductance
Leakage Inductance Fault. Auto-tuning did
not finish within the set time.
• Check the T1 parameters.
• Check motor wiring.
NOTE: * Excessive V/f set value, motor iron core saturation coefficient fault, and rated current set alarm are displayed after the auto tuning is
completed.
