E09
E11
Positioning signal error
Turn off the machine, please check if the encoder in bad connection or is too
loose. To get it right and turn on. If there are still errors, please replace the
control box and call for customer service.
E14 Encoder signal error.
Turn off the system power supply, please check motor encoder connector if loose
or fall off, renew to normal then restart system.

Back-tacking step motor encoder AB
signal abnormal
Turn off the power and check whether the encoder cable of the step motor is
connected to the connector.
E86
Back-tacking step motor failed to
start
Turn off the power and check whether the encoder cable of the motor and the
power cable of the motor are connected to the connector.
