Auto-Tuning Faults

Auto-tuning faults are shown below. When the following faults are detected, the fault is displayed on the digital operator and
the motor coasts to a stop during operation. The fault contact is not activated.

*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
Table 6.4 Auto-Tuning Displays and Processing
•There is an error in the data input
for autotuning.
Er - 01
•There is an error in the relationship
Fault
between the motor output and the
motor rated current.
Er - 02
A minor fault is detected during
auto-tuning.
The STOP key is pressed during
Er - 03
auto-tuning, and the auto-tuning is
interrupted.
Auto-tuning is not completed within
Er - 04
the specified time.
The auto-tuning result became other
than the parameter set range.
Er - 09
The motor did not accelerate in the
specified time.
•Current flow exceeded the motor
rated current.
Er - 12
•Current detection value symbol was
reversed.
•Any of U/TI, V/T2, and W/T3 has
open-phase.
Auto-tuning did not finish within the
set time.
Er - 13
Tuning result became other than the
parameter setting range.
Rated current set value is set too
high.
Diagnostic & Troubleshooting 6 - 12
Probable Cause Corrective Action
• Check input data.
• Check Drive and motor capacity.
• Check motor rated current.
• Check input data.
• Check wirings and around the
machine.
• Check the load.
–
• Check input data.
• Check motor wiring.
• If a motor and a machine are
connected, disconnect the motor
from the machine.
• Increase C1-01 (acceleration time).
• If L7-01 and L7-02 (torque limit
value) are decreased, then increase
the values.
• If a motor and a machine are
connected, separate the motor from
the machine.
• Check current detection circuit,
wiring and mounting procedure.
• Check motor wiring.
• Check input data (especially,
motor output current and motor
rated current value).
