Solution
1. Reset or redirect parameters
2. Check the machinery
3. Check and replace the motor
4. Replace the power board
1. Decrease the idling speed
2. Check the wiring or replace the motor
3. Move the feed mechanism left and
right by hand to check that there is no
abnormal load. (The feed mechanism
is not at the movement limit.)
4. Replace the motherboard
5. Replace the motor
1. Check the wiring
2. Replace the motor
3. Replace the motherboard
Lighten the load
Spare alarm
1. Restart
2. Replace the motherboard
Lighten the load
