How to deal CNC machining center encoder error alarm?
CNC machining center
 
Fault one:
 
The serial encoder communication error alarm of the CNC machining center causes the unit to detect the disconnection of the motor encoder of the CNC machining center or bad communication. Check if the motor's encoder feedback line is connected to the amplifier correctly and firmly. If the feedback line is normal, replace the servo motor (because the motor's encoder is integral with the motor and cannot be disassembled), if it is an alpha motor replacement encoder. If it happens occasionally, it may be due to interference. Check if the shield of the motor feedback line is in good condition.
 
Fault 2:
NC encoder pulse count error alarm (LED display 6, the system's PMM screen display 303/304/305/308 alarm) Analysis: Servo motor serial encoder pulse lost during operation, or do not count . Turn off and on again. If there is still the same alarm, replace the motor (if it is an alpha motor replacement encoder) or the feedback cable. If the alarm disappears after the CNC machining center restarts, you must return to the reference point and then run other commands. If the PMM of the system is a 308 alarm, it may be due to interference, and the power is turned off and on again.
