service.
E17
Machine overturned
1. Turn off the system power and check if the machine is overturned.
2. Check whether the machine protection switch detection setting is correct.
3. If it still does not work normally, please replace the control box or panel and
notify the after-sales service.
E20
Main shaft motor failed to start
1. Turn off the system power, check whether main shaft motor power cord
connector and encoder connector are loose or fall off, restore them to normal
and restart the system.
2. Check whether the motor zero point correction setting is correct, reset the
motor zero point correction
3. If it still does not work normally, please replace the control box or main shaft
motor and notify the after-sales service.
E80
Abnormal communication between
main chip and drive chip
Please replace the control box and notify the after-sales service.
E82
Back-tacking stepper motor
overcurrent
1. Turn off the system power and observe whether back-tacking stepper motor is
stuck. If it is stuck, remove the mechanical failure of the machine first. If it is
normal, check whether connector of back-tacking stepper motor is loose or fall
off, restore it to normal and restart the system.
2. If it still does not work normally, please replace the control box or
back-tacking stepper motor and notify the after-sales service.
E84
The positioning signal of
back-tacking stepper motor encoder
is abnormal
1. Turn off the system power and observe whether back-tacking stepper motor is
stuck. If it is stuck, remove the mechanical failure of the machine first. If it is
normal, check whether the encoder connector of back-tacking stepper motor is
loose or fall off, and restart the system after returning it to normal.
2. Check whether the grating is installed correctly (whether the grating screws
are fastened and whether the grating is in the center of the encoder);
3. Check if there is oil on the grating code plate, if so, please clean it up, and
restart the system after restoration;
4. If it still does not work normally, please replace the control box or
back-tacking stepper motor and notify the after-sales service.
E85
Back-tacking motor encoder signal is
abnormal
1. Turn off the power of the system, check whether the encoder connector of
back-tacking stepper motor is loose or fall off, restore it to normal and restart
the system.
2. Check whether the grating is installed correctly (whether the grating screws
are fastened and whether the grating is in the center of the encoder);
3. Check if there is oil on the grating code plate, if so, please clean it up, and
restart the system after restoration;
4. If it still does not work normally, please replace the control box or
back-tacking stepper motor and notify the after-sales service.
E86
Back-tacking stepper motor failed to
start
1. Turn off the power of the system, check whether the power cord connector of
back-tacking stepper motor and the encoder connector are loose or fall off,
restore them to normal and restart the system.
2. Check whether the grating is installed correctly (whether the grating screws
are fastened and whether the grating is in the center of the encoder);
