FANUC Servo Drive & Motor Repair Common signs of malfunctioning servos include erratic operation & vibration, failure of detection circuits, blown fuses and malfunctioning OVC and HC alarms. When FANUC drives & motors have failed or are running improperly, your CNC machinery is compromised and must be addressed immediately.

- Diagnosis and Correction of Fanuc Alarm Codes. Dealing with alarm codes is a matter of first understanding what they mean, and then deciding what’s causing the code based on the code’s meaning. There’s a list of Fanuc Alarm codes below to help. Diagnosis of alarm codes on the CNC machine can be an expensive time waster.
The Development of KAREL Code
KAREL (pronounced “Carl”) was initially used as an educational tool to teach the elements of programming language to students studying robotics. KAREL has since become a primary FANUC programming language used with robots and robot controllers. This powerful CNC programming language has tremendous capabilities. Tri Star CNC Services works with FANUC machinery parts which rely on KAREL coding.
Here, we’ll cast broad strokes and explain how KAREL works to help you begin to grasp the intricacies of FANUC robot programming. Understanding KAREL can make it easier to troubleshoot your FANUC machinery or know when to get repairs from Tri Star.
How Does FANUC Programming Language Work?
The KAREL World
KAREL is built upon a simple vocabulary of commands to accomplish specific programming tasks. The world – the “space” in which KAREL works – has intersections, walls and beepers to execute its programs within a defined space, made up of X and Y coordinates known as Streets (horizontal) and Avenues (vertical). If, for example, a KAREL program was comprised of 6 Streets and 5 Avenues, it would be written as:
World 6 5
Beepers Command
Within KAREL’s world there are also beepers, which are indicated in KAREL’s programming with the Beepers command. Beepers are small objects placed at intersections of the Streets and Avenues which the robot can sense, and they can be picked up, moved, and set down by the robot when given the proper commands. If, for example, there are 2 beepers at intersection {4, 3} in World 6 5, it would be written as:
World 6 5
Beepers 4 3 2
Beepers 4 3 2
Robot Command

The robot which moves around in KAREL’s world is defined with the Robot command, and it can face North, East, South, or West, as indicated by the commands 1, 2, 3 and 4 respectively. If, for example, the robot in World 6 5 would have a starting position at intersection {4, 3} while facing North (1), and there would be 0 beepers at that intersection, the program would be written as:
World 6 5
Beepers 4 3 2
Robot 4 3 1 0
Beepers 4 3 2
Robot 4 3 1 0
Wall Section Command
Wall sections can also be set up at various points in KAREL’s world, as defined by the Wall command. Walls are only one block long, and can either be north or west of an intersection (indicated by a 1 or 4 respectively). If, for example, you wanted to place a horizontal wall directly North (1) of the intersection {2, 3} within World 6 5, the program would be written as:
World 6 5
Beepers 4 3 2
Robot 4 3 1 0
Wall 2 3 1
Beepers 4 3 2
Robot 4 3 1 0
Wall 2 3 1
Running a KAREL Program on FANUC Machinery
https://truekfil855.weebly.com/mrk-file.html. These four commands define the world in which KAREL lives – running a program is a different story. After establishing KAREL’s world, every program must begin and end with the same lines in order for it to be valid:
Begin:
Bootable recovery disc make iso on pc for mac. BEGINNING-OF-PROGRAM
BEGINNING OF EXECUTION
BEGINNING OF EXECUTION

End:
END-OF-EXECUTION
END-OF-PROGRAM
END-OF-PROGRAM
KAREL robot programs only understand five basic instructions: move (moves by one square in the direction it is facing), turnLeft (turns 90° left), putBeeper (puts a beeper on the square it is standing at), pickBeeper (lifts a beeper off the square it is standing at), and turnoff (the program ends). The simplest KAREL program needs to have at least 5 lines in it for it to be valid.

The Benefits of Working with KAREL in FANUC Robots
The fundamental commands explained above are the basics of KAREL programming language, and robotics engineers all over the world have utilized these commands to develop more intricate programs for FANUC robots. KAREL can be used for advanced FANUC applications involving Ethernet communications, advanced logic processing, and data file manipulation through automatic positioning and programmable acceleration.

What is a FANUC Spindle Drive Alarm 01?
A FANUC Spindle Drive Alarm 01 Code is generated by the CNC when it detects that the inside temperature of the drive motor is higher than the specified temperature. Here is the FANUC Alarm 01 message:
Alarm Code | Message | Description |
Motor Overheat | The Alarm Code 01 detects internal motor temperatures exceeding the specified temperature. |

How to troubleshoot a FANUC Spindle Drive Alarm 01 Code
Step 1 - If a FANUC Alarm 01 Code is issued during cutting:
(a) Investigate the cooling state of the spindle motor.
- If the cooling fan is stopped, check the power supply. Otherwise, replace the cooling fan. The technicians at TIE can help repair or replace the cooling fan on your spindle drive.
- If your spindle drive utilizes a liquid-cooled motor, search for issues with the cooling system.
- Make sure the ambient temperature of the spindle motor is within the appropriate range specified for your unit.
(b) Check the short-period rating. If this alarm is issued when the load meter fluctuates in a limited range, the short-rating period is being exceeded and the load needs to be reduced.
Step 2 - If the Spindle Drive Alarm 01 is generated under a light load:
(a) Make sure the frequency of acceleration/deceleration does not exceed the continuous rating.
(b) Check the specific parameters of the drive motor and make sure they are correctly applied.
Step 3 - If the Alarm 01 is issued when the motor temperature is low:
(a) The spindle motor feedback cable may be faulty. Make sure the CN2 cable is plugged into the CN2 connector. If the CN2 cable is appropriately connected and still registering an Alarm 01 when the motor temperature is low, replace the cable.
(b) Check the control printed circuit board or spindle amplifier. If it is faulty, T.I.E. can replace the control PCB or spindle amplifier to get your CNC machine back up and running.
(c) Investigate the internal thermostat of the motor. If it is faulty, the entire motor may need to be replaced.
