5 Troubleshooting
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 induced voltage constant exceeds
the allowable setting range.
Digital Operator Display
Er-19
Cause
The induced voltage constant inductance
values set to E5-08 or E5-09 exceed 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.
Digital Operator Display
Er-21
Cause
Motor was coasting when Auto-Tuning
was performed.
Either the motor or the PG encoder on
the motor is not properly wired.
The direction for the PG encoder is set
incorrectly, or the number of pulses set
for the PG encoder is wrong.
PG encoder is damaged.

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 (but keep them within reasonable limits).
• First try reducing the test signal amplitude in T3-01 and repeat the tuning. If necessary, then try
reducing the test signal frequency (T3-02) and repeat the tuning.
Inertia Detection Error
• First try reducing the test signal amplitude in T3-01 and repeat the tuning. If necessary, then try
reducing the test signal frequency (T3-02) and repeat the 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 execute
Inertia Tuning.
Induction Voltage Error
Double check the data that was entered to the T2-
PM Inductance Error
Double check the data that was entered to the T2-
Stator Resistance Error
Double check the data that was entered to the T2-
Z Pulse Correction Error
Make sure the motor has stopped completely. Repeat Auto-Tuning.
Check the wiring for the motor and the PG encoder. Repeat Auto-Tuning.
Check the direction and number of pulses set for the PG encoder. Repeat Auto-Tuning.
Check the signal output from the PG encoder attached to the motor. Replace the PG if damaged.
