Possible Cause Solution Fault Type
Motor auto‑tuning
fault
E19.02
E19.04
The synchronous motor
pole position angle
auto‑tuning is faulty.
Check whether the motor is not connected
or output phase loss occurs.
Axis fault
E19.05 The synchronous motor
pole initial position
angle auto‑tuning is
faulty.
Increase the synchronous motor initial
position angle detection current (F2‑29).
Axis fault
E19.06
E19.07
E19.08
The stator resistance
auto‑tuning is faulty.
Confirm that the motor is connected
properly.
Confirm that the rated motor current (F1‑03)
is set according to the motor nameplate.
Axis fault
E19.09
E19.10
The asynchronous
motor transient leakage
inductance auto‑tuning
is faulty.
The motor is not connected or output phase
loss occurs. Confirm that the motor is
connected properly or the motor is
disconnected from the load.
Axis fault
E19.12 The auto‑tuning times
out.
The motor is not connected or output phase
loss occurs. Confirm that the motor is
connected properly or the motor is
disconnected from the load.

E19.19 Axis fault
E19.20 The no‑load zero
position angle auto‑
tuning of synchronous
motor times out.
Check the Z feedback signal. Axis fault
E19.22 Axis fault
E19.23 The synchronous motor
pole position auto‑
tuning is faulty.
Confirm that rated motor current (F1‑03) is
set according to the motor nameplate.
Decrease the synchronous motor initial
position angle detection current (F2‑29).
Axis fault
E19.24 The asynchronous
motor transient leakage
inductance auto‑tuning
is faulty.
The AC drive power class is too low.
Select an AC drive of proper power class
according to the motor power.
Axis fault
EEPROM read‑write
fault
E21.01 EEPROM read‑write is
abnormal.
For parameters written to EEPROM through
communication, check the RAM addresses
and address mapping. For the RAM address
mapping of parameters, see section 1.2 of
MD800 Series AC Drive (Multidrive System)
Communication Guide.
If the EEPROM chip is damaged, contact the
manufacturer to replace the main control
board.
