Cause
Possible Solution
Motor auto-
tuning fault
E 19.02
Synchronous motor
magnetic pole angle
auto-tuning is faulty.
The motor is not connected or output phase
loss occurs.
E 19.04
E 19.05
Synchronous motor
initial magnetic pole
angle auto-tuning is
faulty.
Increase the setting of F2-29 (Synchronous
motor initial angle detection current).
E 19.06
Stator resistance
auto-tuning is faulty.
The motor is not connected.
Set F1-03 (Rated motor current) according to
the motor nameplate.
E 19.07
E 19.08
E 19.09
Asynchronous
motor instantaneous
leakage inductive
reactance auto-
tuning is faulty.
The motor is not connected or output phase
loss occurs.
E 19.10
E 19.11
Inertia auto-tuning
is faulty.
Set F1-03 (Rated motor current) according to
the motor nameplate.
Increase the setting of F2-43 (Inertia auto-
tuning and dynamic speed reference).
E 19.12
Timeout occurs on
auto-tuning.
The motor is not connected or output phase
loss occurs.
Confirm the load is disconnected from the
motor.
E 19.13
E 19.14
E 19.15
E 19.16
E 19.17
E 19.19
Motor auto-
tuning fault
E 19.20
Timeout occurs
on synchronous
motor no-load zero
position angle auto-
tuning.
Check feedback signal Z.
E 19.22
E 19.23
Synchronous motor
magnetic pole angle
auto-tuning is faulty.
Set F1-03 (Rated motor current) according to
the motor nameplate.
Decrease the setting of F2-29 (Synchronous
motor initial angle detection current).
E 19.24
Asynchronous
motor instantaneous
leakage inductive
reactance auto-
tuning is faulty.
The drive power class is small. Select the
proper drive according to the power of motor.
