Fanuc Alarm Code List for Series

Fanuc Alarm Code List For Series 16i/18i/21i

Alarm 0-999: Fanuc alarm, the alarm if above 1000 maker / machinist / machine tool builder.

Alarm 0-250: programs / settings.

Alarm 300 ~: Pulse Coder, servo, interface, cables.

Alarm 400 ~: SVM, Motor, cable, and mechanics.

Alarm 500 ~ : Over travel.

Alarm 7n01 - 99: Spindle motor problems, SPM, Cable, Mechanical, cutting weight.
Alarm 9n01 - 99: Same as above.

Alarm 900-975: the problem is on the motherboard. (CPU cards, Axis cards, SRAM, DRAM)

Tool Change position (TCP) procedure for eatch axis in fanuc control

Tool Change position (TCP) procedure for eatch axis in Fanuc control

For each Axis, If alarm occurred X/Y/Z Axis not a tool change position (TCP) fllow the procedure

For Maximum Value/Range +X/+Y/+Z

1. Check bit F70.3/F70.4/F70.5 for eatch Axis on TCP positions make sure if it is 0 then after set TCP positions

2. Press system key

3. Press PRAM key

4. For eatch Axis set +X/+Y/+Z direction,Find Max. Value parameter no 6933,6934,6935 for eatch Axis X/Y/Z by pressing NO. SRH key and TCP value notedown for example TCP value is 99692

5. Now +500 add in Current value like 99692+500= 100192

6. TCP Value 100192 put in parameter 6933,6934 & 6935 for eatch Axis X/Y/Z

7. Now +X/+Y/+Z axis TCP positions set for +X/+Y/+Z direction

8. If TCP positions set properly during Tool change position bit F70.3/F70.4/F70.5 it will change 0 to 1

For Minimum value/Range -X/-Y/-Z

1. Check bit F70.3/F70.4/F70.5 for eatch Axis on TCP positions make sure if it is 0 then after set TCP positions

2. Press system key

3. Press PRAM key

4. For eatch Axis set -X/-Y/-Z direction,Find Min. Value parameter no 6953,6954,6955 for eatch Axis -X/-Y/-Z by pressing NO. SRH key and TCP value notedown for example TCP value is 5500

5. Now -500 minus in Current value like 55000 -500= 54500

6. Value 54500 put in parameter 6953,6954 & 6955 for eatch Axis X/Y/Z

7. Now -X/-Y/-Z axis TCP positions set for -X/-Y/-Z direction

8. If TCP positions set properly during Tool change position bit F70.3/F70.4/F70.5 it will change 0 to 1

Spindle Orientation procedure in fanuc control

Spindle Orientation procedure

1. Press systems key

2. Press diagnosis function key

3. Search parameter 445 by pressing NO. SRH key and check spindle position in parameter 445 and note down the position value

4. Press system key

5. Press PARAM key and search parameter 4077 by pressing NO. SRH key

6. Manually tenon position set for orientation position whare you want

7. Again Search parameter 445 by pressing NO. SRH key and check spindle position in parameter 445,Example like 2111

8. Put Spindle position in parameter no 4077

9. Now spindle orientation set

Axis Refrence (Zero Return) procedure of eatch axis in fanuc control

Axis Refrence (Zero Return) procedure

Move the axis to where you want to zero return position
Select "MDI" mode
Press the function key “OFFSET SETTING”
Press the “SETTING” key
Move the cursor to “PARAMETER WRITE” . May need to page up or down to get to the top of the Parameter numbers.
Turn on PWE (Parameter Write) make it a 1
Press the "SYSTEM" key
Press the "PARAM" key
Type1815 and press "No.Search" . This should bring up parameter 1815.
Arrow down to whichever axis you want to change X,Y,or Z.
Change bit of APZ 1 to 0 (This will delete the current reference zero).
Alarm will occurred need to ZRN
Power off machine for one minute and power up
Go back to the parameter 1815 and make bit of APZ 0 to 1
Power off machine for one minute and power up
Now new home position will be set

Encoder and Tpyes of Encoder

Encoder: In general an encoder is a device or process that converts data from one format to another. In position sensing, an encoder is a device which can detect and convert mechanical motion to an analog or digital coded output signal. More specifically, it measures the position, while velocity, acceleration and direction can be derivated from the position in either linear or rotary movement.

Types of Encoder are:
