Autotuning Faults

Autotuning faults are shown below. When the following faults are detected, the fault is displayed on
the digital operator and the motor coasts to stop. No fault or alarm outputs will be operated.

Meaning
Function Selection Error
A setting has been made that is applicable with the cur-
rent control method.
Example: A function used only with open loop vector
control was selected for V/f control.

Meaning
Motor data fault
Alarm
STOP key input
Line-to-Line Resistance Fault
Autotuning result is outside the parameter setting
range.
No-Load Current Fault
Autotuning result is outside the parameter setting
range.
Rated Slip Fault
Autotuning result is outside the parameter setting
range.
Acceleration Fault (Rotating autotuning only)
The motor did not accelerate in the specified time
(C1-10+10sec.)
Motor Speed Fault (Rotating autotuning only)
The torque reference exceeded 100% during accel-
eration. Deteceted only when A1-02 = 2 or 3 (Vector
control modes).
Current Detection Fault
• The current exceeded the motor rated current.
• Any of U/T1, V/T2 and W/T3 has open-phase.
Leakage Inductance Fault
Autotuning result is outside the parameter setting
range.
Rated Current Setting Alarm
Displayed after auto-tuning is complete
During auto-tuning, the measured value of motor
rated current (E2-01) was higher than the set value.
Motor Core Saturation Alarm
(only for rotating autotuning)
Rated Current Setting Alarm
During autotuning the measured value of motor rated
current (E2-01) was greater than the set value.
Corrective Actions
Verify the control method and the function.
Check parameters (E1- ). A frequency/voltage value
may be set higher than the maximum frequency/voltage.
Corrective Actions
• Check the input data.
• Check the Inverter and motor capacity.
• Check the motor rated current and no-load current set-
ting.
• Check the input data.
• Check wiring and the machine.
• Check the load.
-
• Check the input data.
• Check the 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 voltage (E1-01), change the input data.
• Increase C1-01(Acceleration time)
• Increase L7-01 and L7-02 (Torque limits)
• If the motor is connected to the machine, disconnect it.
• If the motor is connected to the machine, disconnect it.
• Increase C1-01
• Check the input data (particularly the number of PG
pulses and the number of motor poles)
Check wiring of the Inverter and the mounting.
Check motor wiring.
Check the motor rated current value.
• Check the input data
• Check the motor wiring.
• If the motor is connected to the machine, disconnect it.
Check the motor rated current value
