Error Code
Description Troubleshooting
1
Motor short (over
current) detected
E01 SHORT
or
ERR E01
The short of three motor phases is detected.
(1) After power-off, unplug the UVW-phase connector at the
drive-
side and measure the resistance between each phase of
UVW and ground to check if there is a short circuit. The short
circuit may burn the motor.
(2) Measure the line-to-line resistance between motor UVW
phases to check that they are close to the specification. If the
line-to-
line resistance is lower than the specification too much,
the motor may be burned.
(3) Separate the motor from the motor power cable, and use a
multimeter to check if the motor power cable is short.
2
Over voltage
detected
E02 OVERV
or
ERR E02
The DC bus voltage in the drive exceeds the limit.
When the motor has a heavy load and is operated at high speed,
the back EMF exceeding the voltage limit will cause this error.
Check if the regenerative resistor needs to be installed, which is
selected according to the load and the motion specification.
3
Position error too
big
E03 PEBIG
or
ERR E03
The position error is greater than “maximum pos error” set in the
“Motion Protection” area.
(1) Check if the gain tuning is improper.
(2) Confirm that the maximum position error is set properly
(“Application center” -> “Protection” -> “maximum pos error”).
(3) Check if the motor movement is obstructed.
(4) Check if the load is too heavy.
(5) Check if the guideway is without maintenance for a long time.
(6) Check if the cable tray is installed too tight.
(7) “W05 SVBIG” continues occurring before “E03”. Use 220 V
power.
4
Encoder error
E04 ENCOD
or
ERR E04
The encoder signal is incorrect or the alarm pin reports an error.
(1) Confirm that all encoder connectors are connected firmly.
(2) Confirm that the encoder wiring is correct.
(3) If the encoder is a digital type, it may be caused by the
external interference. Confirm that the encoder cable has an
anti-interference twisted wire and shield, or is equipped with
an iron core.
5
Soft-thermal
threshold reached
E05 SWHOT
or
ERR E05
Motor overload. (The software detects the motor over-temperature.)
(1) Confirm that the continuous current and peak current during
motor movement comply with the motor specification.
(2) Check if the motor movement is obstructed.
(3) It can be eliminated by resetting and re-enabling the drive.
However, if the current exceeds the motor specification due to
the load and motor parameters, it may occur again.
(4) Reduce the speed, acceleration, and deceleration.
(5) Check if the motor model name or motor current parameter is
set incorrectly.
6
Motor maybe
disconnected
E06 UVWCN
or
ERR E06
The motor power cable is not physically connected to the drive.
(1) Check if the connector of UVW cable is loose.
(2) Check if the motor model name is set incorrectly.
7
Amplifier over
E07 D.HOT
The drive is over temperature.
