1. First open the diagnostic screen:

1) Press the [SYSTEM] key

2) Press the soft key [Diagnosis] to enter the diagnosis screen

 

2. Then press the [PAGEDOWN↓] key several times to find the diagnosis as follows:

1) Check if the servo motor is overheated

 

 

2) Servo motor and encoder temperature

 

 

3) Spindle motor temperature

 

 

 

3 The display method of machine tool load is as follows:

 

 

In the vertical machining center, the Z axis load is relatively large, and some machine tools may be more than 50%, but the Z axis load exceeds 80% for a long time, the life of the Z axis motor will have a great impact, you can add a separate Z axis motor Cooling fan.

 

4 The FANUC fan is a consumable product. There are fans in the servo drive, CNC system and spindle motor. When idle maintenance, according to the situation of the electrical cabinet, replace it in time.

① System fan, +24V, three-wire. If there is an alarm 701, it can be shielded with the parameter 8109#1.

② Fans on power supply, servo and spindle drive.

 

 

 

 

 

The internal fan of the power drive, as shown below:
