Errors During Autotuning
The
errors that can occur during autotuning are given in the following table. If an error is detected, the motor
will
coast to a stop and an error code will be displayed on the Digital Operator. The error contact output and
alarm
output will not function.

Parameters
E1-04, E1-06, E1-07, and E1-09 do not satisfy the following conditions:
• E1-04
(FMAX) ≥ E1-06 (FA) > E1-07 (FB) ≥ E1-09 (FMIN)
• E3-02
(FMAX) ≥ E3-04 (FA) > E3-05 (FB) ≥ E3-07 (FMIN)

Parameter setting error
One
of the following parameter setting errors exists.
• C6-05
(Carrier Frequency Gain) > 6, the Carrier Frequency Lower Limit (C6-04)
>
the Carrier Frequency Gain(C6-05)
• Upper/lower
limit error in C6-03 to 05.
• C6-01
is 0 and C6-02 is 2 to E.
• C6-01
is 1 and C6-02 is 7 to E.
EEPROM
R/W
Err
EEPROM write error
A
verification error occurred when writing EEPROM.
• Try
turning the power supply off and on again.
• Try
setting the parameters again.

Data
Invalid
Motor
data error
There
is an error in the data input for
autotuning.
There
is an error in the relationship
between
the motor output and the motor
rated
current.
The
is an error between the no-load cur-
rent
setting and the input motor rated
current
(when autotuning for only line-
to-line
resistance is performed for vector
control).
• Check
the input data.
• Check
the capacity of the Inverter and
motor.
• Check
the motor rated current and no-
load
current.
Minor
Fault
Alarm
A
minor fault occurred during autotun-
ing
(xxx).
• Check
the input data.
• Check
wiring and the machine.
• Check
the load.
STOP
Key
STOP
key input
The
STOP Key was pressed to cancel
autotuning.

tance
error
Autotuning
was not completed in the
specified
time.
The
results of autotuning has exceeded
the
setting range for a parameter.
• Check
the input data.
• Check
motor wiring.
• If
the motor is connected to the
machine,
disconnect it.
• If
the setting of T1-03 is higher than
the
Inverter input power supply volt-
age
for Er-08, change the input data.

Accelerate
Acceleration
error
(detected
only for
rotational
autotuning)
The
motor did not accelerate in the spec-
ified
time.
• Increase
C1-01 (Acceleration Time 1).
• Increase
L7-01 and L7-02 (Reverse
Torque
Limits) if they are low.
• If
the motor is connected to the
machine,
disconnect it.
