Current overload protecting
1． Over rated loaded or the motor is stuck,
cause excessive current, machine will
start self-protecting system. Adjust the
machine and restart;
change a signal light.
2. Check if the motor has noise from motor
or if the motor / bottom control board
were burnt out, if burnt out, change
motor and bottom control;
3. Check if the power voltage is wrong, use
right voltage to test again.
1． The safety key is not at the
appointed site
2. The safety key is not
connected well or broken.
1． Check if the safety key is at the
appointed site.
2. Check if the safety key sensor board is
connected well
3. Replace the safety key sensor board
inside computer
If the motor doesn’t rotate after press “START” button. The wire that controls the motor might
have something wrong. Such as the protective tube on control board is damaged or fall off, Or
the motor wire isn’t connected well. Or the IGBT on control board is burnt out Check if the motor
wire is connected well and re-connect well. Check if the protective tube is OK, re-set it or change
one. Use multimeter to test if the IGBT is burnt out, and change an IGBT or control board.
E07/E08
EEPROM damaged
Change a control board
E02
E01
E03
Message wire is broken or not
connected well
1． Check if the computer and bottom
control board wire connect well.
2． Check if IC on bottom control board is
loosen, reset the IC
1. Burst clash
1． Check if the power voltage is 50%
lower than the normal voltage, please
use the normal voltage to test;
2．Check if the control board is burnt with
irregular smell, replace a control board;
3. Check if the motor wire is well
connected, reconnect it.
No sensor signal
1． Check if the signal light on control board
is light on, if the signal light is burnt out,
change a signal light.
2. Check if the plug of sensor is well
connected .
3. Check if the magnetic sensor is broken or
well connected, reconnect it or replace a
magnetic sensor.
