Err19
Motor auto-
tuning fault
101, 102:
The motor auto-tuning
times out.
101, 102:
•
Enter the motor parameters
correctly.
•
Check the motor wiring and
whether phase loss occurs on the
contactor at the output side.
•
Check the encoder wiring and
ensure that the encoder PPR is
set properly.
•
Check whether the inspection
button is released before the
PMSM with-load auto-tuning is
nished.

Err20
Speed
feedback
incorrect
1: AB signals are lost
during auto-tuning.
4: Z signal cannot be
detected during auto-
tuning.
5: The CD signal cables
of the SIN/COS encoder
break.
7: The UVW cables of
the UVW encoder break.
8: Reserved.
9: Overspeed occurs or
the speed deviation is
too large.
10/11: AB signals or CD
signals of the SIN/COS
encoder are interfered
with.
12: The detected speed
is 0 at torque limit.
13: AB signals are lost
during running.
14: Z signal is lost during
running.
19: The AB analog signal
cables break during low-
speed running.
55: CD signal error
or serious Z signal
interference occurs
during auto-tuning.
1 to 19:
•
Check that the setting of F1-
00, F1-12, and F1-25 for the
synchronous motor is correct.
•
Check that there is no mechanical
stuck.
•
Check that the brake has been
released during running.
55:
Check that the grounding is reliable
and eliminate interference problems.
