Fault Code Name Possible Causes Solution Level
Err17
Encoder
interference
during motor
auto-tuning
Subcode 1: Reserved. -
5A
Subcode 2: The SIN/
COS encoder signal
is abnormal.
Serious interference exists in the C, D, and Z
signals of the SIN/COS encoder. Check whether
the encoder cable is laid separately from the
power cables, and whether system grounding is
reliable.
Check whether the PG card is wired correctly.
Subcode 3: The UVW
encoder signal is
abnormal.
Serious interference exists in the U, V, and W
signals of the UVW encoder. Check whether
the encoder c cable is laid separately from the
power cables, and whether system grounding is
reliable.
Check whether the PG card is wired correctly.
Err18
Current detection
fault
The drive control
board fails.
Contact us or our agent directly. 5A
Err19
Motor auto-
tuning fault
Subcode 1: Learning
the stator resistance
fails.
Check whether the motor wiring is correct.
5A
Subcode 5: Learning
the magnetic pole
position fails.
Subcode 8: The
synchronous motor
static auto-tuning
mode is selected, but
the encoder is not
SIN/COS.
Select another auto-tuning mode or use a SIN/
COS encoder.
Subcode 9: CD signal
uctuation is large in
synchronous motor
static auto-tuning.
Hardware interference exists. Check whether
grounding is correct.
Subcode 12: Leaning
the encoder zero-
position angle fails in
synchronous motor
angle-free auto-
tuning.
Obtain the encoder zero-point angle in
inspection state, and then perform half-
automatic angle-free auto-tuning under normal-
speed running.
