Acceleration Error
C a u s e
P o s s ib le S o l u t i o n s
The motor did not accelerate for the specified
acceleration ramp.
Lengthen the acceleration ramp (C1-01).
Torque limit when motoring is too low (L7-01 and
L7-02).
• Check the settings o f parameters L7-01 and L7-02.
• Increase the setting o f L7-01 and L7-02.
The load during Rotational Auto-Tuning was too
high.
• Disconnect the motor from m achine and restart Auto-Tuning. If motor and load cannot be uncoupled make sure the load is lower
than 30%.
• If a m echanical brake is installed, make sure it is fully lifted during tuning.

Motor Direction Error
C a u s e
P o s s ib le S o l u t i o n s
The encoder signal lines are not properly connected
to the drive.
Check and correct wiring to the PG encoder.
Motor and PG direction are opposite.
Check the motor speed monitor U 1-05 w hile turning the motor manually in forward direction. If the sign displayed is negative,
change the setting o f parameter F1-05.
The load pulled the motor in the opposite direction
o f the speed reference and the torque exceeded
100%.
Uncouple the motor from the load and repeat Auto-Tuning.

Motor Speed Fault
C a u s e
P o s s ib le S o l u t i o n s
Torque reference is too high.
• Lengthen the acceleration ramp set to C1-01 (i.e., increase the acceleration time.)
• Disconnect the m achine from the motor, if possible.

Current Detection Error
C a u s e
P o s s ib le S o l u t i o n s
One o f the motor phases is m issing:
(U/T1, V/T2, W/T3).
Check motor wiring and correct any problems.
Current exceeded the current rating o f the drive.
• Check the motor wiring for a short between motor lines.
• Make sure the motor contactor is closed during tuning.
• Replace either the control board or the entire drive. For instructions on replacing the control board, The current is too low. contact
Yaskawa or your nearest sales representative.
The current is too low.
Attempted Auto-Tuning without motor connected to
the drive.
Connect the motor and perform Auto-Tuning.
Current detection signal error.
Replace either the control board or the entire drive. For instructions on replacing the control board, contact Yaskawa or your nearest
sales representative.

Leakage Inductance Error
C a u s e
P o s s ib le S o l u t i o n s
Drive was unable to complete tuning for leakage
inductance within 300 seconds.
• Check all wiring and correct any mistakes.
• Double-check the motor rated current value that was entered to T1-04 for Auto-Tuning.
• Check the motor rated current value written on the motor nameplate and enter the correct value.

Z Pulse Correction Error
C a u s e
P o s s ib le S o l u t i o n s
Motor was coasting when Auto-Tuning was
performed.
Make sure the motor has stopped completely. Repeat Auto-Tuning.
Either the motor or the encoder on the motor is not
properly wired.
Check the wiring for the motor and the encoder. Repeat Auto-Tuning.
The direction for the encoder is set incorrectly, or the
number o f pulses set for the encoder is wrong.
Check the direction setting by F1-05 and b1-14 and number o f pulses (F1-01) set for the encoder. Repeat Auto-Tuning.
Encoder is damaged.
Check the signal output from the encoder attached to the motor. Replace the encoder if damaged.
