Digital Operator Display
Er-13
Cause
Drive was unable to complete tuning for
leakage inductance within 300 seconds.
Digital Operator Display
Er-14
Cause
The motor speed exceeded twice the
amplitude of speed reference during Inertia
Tuning.
Digital Operator Display
Er-15
Cause
The output torque reached the torque limit
set in L7-01 through L7-04 during Inertia
Tuning.
Digital Operator Display
Er-16
Cause
The inertia identified by the drive was
abnormally small or abnormally large
during Inertia Tuning.
Digital Operator Display
Er-17
Cause
Drive is prohibited from rotating the motor
in reverse while attempting to perform
Inertia Tuning.
Digital Operator Display
Er-18
Cause
The result of Back EMF Constant Tuning
(induced voltage) exceeds the allowable
setting range.
Digital Operator Display
Er-19
Cause
The induced voltage constant attempted to
set a value to E5-08 or E5-09 that is outside
the allowable range.
Digital Operator Display
Er-20
Cause
Stator resistance tuning attempted to set a
value to E5-06 that is outside the allowable
setting range.

Leakage Inductance Error
• Check all wiring and correct any mistakes.
• Check the motor rated current value written on the motor nameplate and enter the correct value to T1-04.
Motor Speed Error 2
Reduce the ASR gain set to C5-01.
Torque Saturation Error
• Increase the torque limits in L7-01 through L7-04 within reasonable limits.
• Reduce the test signal frequency in T3-01 and restart Auto-Tuning. If necessary, reduce the test signal
amplitude (T3-02) and restart Auto-Tuning.
Inertia ID Error
• Reduce the test signal frequency in T3-01 and restart Auto-Tuning. If necessary, reduce the test signal
amplitude (T3-02) and restart Auto-Tuning.
• Check the basic motor inertia value entered to T3-03.
Reverse Prohibited Error
• Inertia Auto-Tuning cannot be performed if the drive is restricted from rotating in reverse.
• Assuming it is acceptable for the application to rotate in reverse, set b1-04 to 0 and then perform Inertia
Tuning.
Induction Voltage Error
Double-check the data entered to the T2-oo parameters and restart Auto-Tuning.
PM Inductance Error
Double-check the data entered to the T2-oo parameters and restart Auto-Tuning.
Stator Resistance Error
Double-check the data entered to the T2-oo parameters and restart Auto-Tuning.
