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
Fanuc Robot Ovc Alarm
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:
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.
Example program of how to turn a KAREL program off:
BEGINNING-OF-PROGRAM
BEGINNING-OF-EXECUTION
turnoff
END-OF-EXECUTION
END-OF-PROGRAM
BEGINNING-OF-EXECUTION
turnoff
END-OF-EXECUTION
END-OF-PROGRAM

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 414 Servo Alarm?
A FANUC 414 servo alarm is generated by the CNC when it detects that an amplifier has a high current alarm 8, 9, or A. To determine the exact cause, you must go through the process of elimination. The high current alarm may be caused by the servo drives, amplifiers, modules, motor and/or cables.
In some instances, this alarm may indicate a short to ground. The short is causing too much current to flow through the power module inside the amplifier and will eventually cause it to break.
Here is the FANUC 414 Servo Alarm message:
Alarm Code | Message | Description |
414 | SERVO ALARM: n–TH AXIS – DETECTION RELATED ERROR | N–th axis (axis 1–8) digital servo system fault. Refer to diagnosis display No. 200 and No. 204 for details. Look at the servo amplifier for alarm code. |
How to Diagnose a FANUC 414 Servo Alarm:
Step 1 - Access the electronics cabinet with the power on (WARNING: Hazardous voltage inside).
Step 2 - Look for the amplifier unit displaying either FANUC servo alarm 8, 9, or A on the seven segment display.
Step 3 - Alarm 8, 9, and A are all the same problem. However, the different alarms identify which amplifier axis the alarm exists on.
What Is Ovc Alarm In Fanuc Robot Parts List
Code | Message | Description |
Alarm 8 | Abnormal current alarm (L axis) | Located below the logic board, Alarm 8 indicates an abnormal current in the first axis on the amplifier which is labeled (L). |
Alarm 9 | Abnormal current alarm (M axis) | Located below the logic board, Alarm 9 indicates an abnormal current in the second axis on the amplifier which is labeled (M). |
Alarm A | Abnormal current alarm (N axis) | Located below the logic board, Alarm A indicates an abnormal current in the third axis on the amplifier which is labeled (A). If your amplifier only controls two axes, your CNC should never display an Alarm Code A. |
Step 4 - Turn on the main breaker of the machine and leave the CNC off.
a. If FANUC servo alarm 8, 9, or A appears when the CNC is off, disconnect the feedback connector to the amplifier axis indicated by the alarm and turn on the main breaker with the CNC off again.
i. If no alarm appears, there is an issue with the feedback cable or the pulse coder.

ii. If alarm 8, 9, or A appears with the feedback cable disconnected, the amplifier is most likely faulty and needs to be replaced.
b. If the alarm ONLY appears when the CNC is turned on, you need to troubleshoot the drive, motor, and power cable.
Step 5 - Disconnect the four motor leads from the bottom of the amplifier.

Step 6 - Turn on the CNC and release any emergency stop condition (if you’re removing the motor power with a vertical axis, physically prop up the axis or else it will fall when the emergency stop and servo motor brakes are released).
Step 7 - If an alarm 8, 9, or A still appears, the drive is probably faulty and needs to be replaced.
Alesis io trigger. The Trigger iO works plug-and-play with Mac and PC, and is powered by its USB connection when working with a computer. You can also wall-power it when working with non-USB MIDI sound sources. You can mount the Trigger iO on virtually stand or rack using the optional E-Percussion Module Mount and integrate it cleanly into your drum set.
Step 8 - If an alarm doesn’t appear, the motor and/or power cable may be faulty and needs to be diagnosed.
Step 9 - With an ohm meter, check for shorts in the motor by measuring leg-to-leg and leg-to-ground on all three legs. An ohmmeter will tell you if your motor is shorted. Leg-to-leg readings should be low, but consistent, on all three legs. The leg-to-ground readings should be open (OL) on all three legs-to-ground.
Step 10 - With a megger, check each leg-to-ground. A megger will tell you if your motor is grounded. The reading should show infinity (or 500 MEG and above) at the 1000V setting. Check all three legs-to-ground because the problem can be in the power plug/terminal box of the motor or the power cables going from the drive to the motor.
