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.

Meaning
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)
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.
A verification error occurred when writing EEPROM.
• Try turning the power supply off and on again.
• Try setting the parameters again.
Table 7.4 Errors During Autotuning
Meaning
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.
Motor data error
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).
A minor fault occurred during autotun-

Line-to-line resis-
tance error
Autotuning was not completed in the
specified time.
No-load current error
The results of autotuning has exceeded
the setting range for a parameter.

Incorrect settings
Probable causes Corrective Actions
• Check the input data.
• Check the capacity of the Inverter and
motor.
• Check the motor rated current and no-
load current.
• Check the input data.
• Check wiring and the machine.
• Check the load.
• 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.
• 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.
