11. TROUBLE SHOOTING GUIDE
CODE
SOLUTION
E01
Reason
: signal failure within the connection between computer and controller
Solution
:
A.
Check that the wires connecting the
computer and controller
are not
damaged and
are connected well.
B. Replace the IC of controller or computer
.
E02
Reason
: The voltage of the motor is not detected by controller
Solution
:
A. Check whether the positive and negative line of motor are successfully
connected with the controller terminal interface
B. Check if the power tube on the controller and peripheral components are
damaged
C. Consider replacing controller or motor
E03
Reason
: Speed feedback is not detected by controller when motor is running
Solution
:
A. Check if the motor rotates when the machine starts before displaying
E03. If so, conduct the following checks.
1. Check that the speed sensor is attached well.
2. Check that the speed sensor wires are not damaged
3. Check that the interface between light sensor and 4 white pin on
the controller is connected well
4. Check if the peripheral area of the four white pin is damaged
5. Consider replacing controller and IC
B. If the motor does not running when you start the machine and E03
shows, check if the motor is stuck. If the problem persists, consider
replacing the motor.
E05
Reason
: The voltage is over the protection value when the motor is running.
Solution
:
A. Check if the motor is in good condition, and if there anything stuck in
running belt or roller so as to unnaturally increase the resistance of for
the motor.
B. Replace the controller
