Analysis of common faults of servo motors
 

First, the motor overcurrent overload alarm
1. The motor is improperly installed or the mechanical load is too large, resulting in overload alarm.

Solution: Install correctly, reduce mechanical load or replace the high-torque motor.

2. Water ingress of the motor.

The motor stator coil is less than 10MΩ insulated to ground, and the power socket is short-circuited between phases.

Solution: Cleaning and drying stator insulation resistance should be greater than 100MΩ, if the requirements are not met, replace the power socket or motor stator.

This is due to poor waterproof treatment, which causes a large amount of cutting fluid to enter the motor, so that the motor insulation layer is damaged and the ground is short-circuited. Previous article:FANUC motor is flooded, how to measure? 

3. When the user replaces the encoder by himself, he forgets to install the coupling or the encoder detects errors. Causes an alarm. Solution: Replace the encoder or coupling with a new one.

Second, the motor overheating alarm (430 alarm)

1. Due to poor waterproof treatment, a large amount of cutting fluid enters the motor, so that the motor insulation layer is damaged and the ground is short-circuited.

2. The temperature sensor detects the error and the temperature sensor is damaged. The normal value should be between 55-80kΩ, and the resistance value varies with ambient temperature. Solution Method: Send the motor back to the company for repair;

3. Improper installation of the motor and excessive me

After entering the system, how to package the backup data?

      The new version of the 0I-C system can back up SRAM files in the normal boot state of the system, which can only be backed up under BOOT in the past, the steps are as follows:

1 PRM3116#0=1 

2 EDIT MODE 

3 Press SYSTEM—ALL I/O--->---> until M-CARD is displayed 

 4 After pressing the operation key, the following screen appears:

 5 Press the emergency stop and select the EDIT mode and press SAVE to appear after the following screen appears:

6 DISPLAY when BACKUP is complete:

7 The LOAD SRAM method is the same as above
