Encoder
interference
during motor
auto-tuning
● Subcode 1: Reserved.
● Subcode 2: The SIN/
COS encoder signal is
abnormal.
● Subcode 3: The UVW
encoder signal is
abnormal.
Subcode 2:
● Serious interference exists in the C, D,
and Z signals of the SIN/COS 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.
Subcode 3:
● 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.

Err19
Motor auto-
tuning fault
● Subcode 1: Learning the
stator resistance fails.
● Subcodes 5, 6: Learning
the magnetic pole position
fails.
● Subcode 8: Reserved.
● Subcode 11: Saving the
angle fails at synchronous
motor angle-free auto-
tuning.
● Subcodes 101, 102: Motor
auto-tuning fails.
Subcodes 1, 5, 6:
Check the motor wiring and whether phase
loss occurs on the contactor at the output
side.
Subcode 11:
At angle-free motor auto-tuning, the power is
cut off when the motor rotary displacement is
too small, and this fault is reported at direct
running upon power-on again. To rectify
the fault, perform angle-free motor auto-
tuning again and make the motor runs for
consecutive three revolutions.
Subcode 101:
● Synchronous motor with-load auto-tuning
times out.
● Check encoder wiring is correct, or
replace the PG card and perform motor
auto-tuning again.
Subcode 102:
● Motor auto-tuning times out in operation
panel control mode.
● Check encoder wiring is correct, or
replace the PG card and perform motor
auto-tuning again.
