the electronic meter;
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 meter 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 electric machine
has been installed well.
Change
the
electric
machine.
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
joint to ensure that it is
reliable.
Check whether lifting motor's
AC
wires
are
properly
connected.
Lifting motor shall be
correctly
plugged
according to marks on its
AC controller.
Check whether motor wiring is
damaged to form open circuit.
If yes, replace wires or
replace the lifting motor
Check whether the lifting motor
is damaged.
If yes, change the lifting
motor.
Lifting motor fails in learning.
Press
the
button
of
controller for 3 seconds
and relearn again.
E05
Over-current protection
Check whether the controller
match with the standard of
electric engine.
Change
the
electric
machine or controller and
retest.
E06
Fault of motor’s open circuit
Check
whether
the
motor
interface of the drive is loose.
Re-plug
the
motor
interface properly.
Check whether the motor is
open-circuited.
Change the motor.
When the motor is idling, if the
current is less than standard, it
will go wrong, please install the
machine and test.
