ERROR
POSSIBLE REASONS
TEST METHOD
SOLUTIONS
E01
Communicational failure
between the meter and the
controller, and the drive cannot
receive signal from the meter.
Check whether the connector
of the console and the
controller has broken down.
If yes, change the
connector.
Check whether the joint has
been plugged in well.
Pull the joint and plug in
again.
E02
Explosion proof protection
Whether the supply voltage is
50% lower than the normal
voltage.
Use correct voltage
standard and retest.
Whether the control board has
been installed well.
Change the control board.
Whether the controller has
awful smell.
Change the controller.
E03
Failure in inspecting the motor
signal for more than 15 seconds
continuously and speed sensor
for 10 seconds continuously.
Whether the distance and
location of the sensor and the
disc is correct or the sensor is
installed well.
The sensor should be
installed right in the hole
of disc.
Whether the sensor wire has
been open circuited, short
circuited or broken circuited.
Reconnect the motor
interface, and examine
the sensor wire.
Whether the sensor has been
broken down.
Change the sensor.
E04
Lifting learning or self-inspection
fails.
Check whether motor wiring is
damaged to form open circuit.
Re-insert the signal wire

Check whether motor wiring is
damaged to form open circuit.
If yes, replace wires or
replace the incline motor
Check whether the incline
motor is damaged.
If yes, change the incline
motor.
Incline motor fails in learning.
