Professional CNC CNC machining process, the servo module of 185V rectification, AC into DC 300V, DC side has a check resistor to detect DC current, if there is a short circuit behind, immediately generate an alarm.
If it has been occurring, you can use a multimeter to measure whether the main circuit transistor module short-circuit, transistor module for transistor module. If there is no short circuit, you can exchange the control board with cnc CNC lathe machining center different from other axes, if the migration with the control board, the control board is repaired.
If the c precision CNC CNC machining center is different for high speed alarm, low speed normal may be a problem with the control board or motor, also can be identified according to the exchange of servo module.
Observe and check whether the cnc CNC lathe machining center always alarm or occasionally, if the alarm is a module or control board failure, otherwise it may be the motor.
High voltage alarm (HVAL red light illuminated)
cnc cnc lathe machining center different servo control board detected to the main circuit or control circuit voltage is too high, generally is the detection circuit failure.
Check whether the three-phase 185V input voltage is normal.
Check CN2 of 1.2.3 AC +, -18V are normal?
If the exchange control circuit board, cnc with the migration of the control board, the abnormal failure of the CNC lathe machining center is the circuit board failure.
