● Subcode 1:The encoder
signal is not detected
during synchronous motor
no-load auto-tuning.
● Subcode 2: Reserved.
● Subcode 3: The phase
sequence of the motor is
incorrect.
● Subcode 4: Z signal
cannot be detected during
synchronous motor auto-
tuning.
● Subcode 5: The cables
of the SIN/COS encoder
break.
● Subcode 7: The cables of
the UVW encoder break.
● Subcode 8: Reserved
● Subcode 9: The speed
deviation is too large.
● Subcode 10, 11:
Reserved.
● Subcode 12: The encoder
AB signals are lost at
startup.
● Subcode 13: The encoder
AB signals are lost during
running.
● Subcodes 14–18:
Reserved.
● Subcode 19: The signals
of the SIN/COS encoder
are seriously interfered
with during running.
● Subcode 55: The signals
of the SIN/COS encoder
are seriously interfered
with or CD signals are
incorrect during motor
auto-tuning.
Subcode 1, 4, 5, 7:
● Check whether the encoder signal circuit
is normal.
● Check whether the PG card is normal.
Subcode 3:
Exchange any two phases of the motor UVW
cables.
Subcode 9:
● The angle of the synchronous motor is
abnormal. Perform motor auto-tuning
again.
● The speed loop proportional gain is small
or integral time is large. Increase the
proportional gain or decrease the integral
time properly.
Subcode 12:
● Check whether the brake has been
released.
● Check whether AB signal cables of the
encoder break.
● If the motor cannot be started at the slip
experiment, perform the slip experiment
by using the function set in F3-24.
Subcode 13:
AB signals of the encoder become loss
suddenly. Check whether encoder wiring is
correct, whether strong interference exists,
or the motor is stuck due to sudden power
failure of the brake during running.
Subcode 19:
The encoder analog signals are seriously
interfered with during motor running, or
encoder signals are in poor contact. You
need to check the encoder circuit.
Subcode 55:
The encoder analog signals are seriously
interfered with during motor auto-tuning, or
encoder CD signals are in wrong sequence.
