1-0 AND 2-0 ,
The pulsecoder in models 3-0,4-0 AND 5-0 Cannot be replaced because it is directly assembled onto the motor.
REMOVAL OF A PULSECODER.
Remove the red endcap of the motor.
Look for a small line on one of the three mounting tabs. It should be aligned with a mark on the endbell of the motor if not , Please make one (Never remove the mounting tab bracket from a pulsecoder)
Remove the rubber cap on the back of the pulse coder.
Fanuc Robot Programming Manual
Remove the allen head screw from the inside of the pulsecoder.
Remove the three mounting screws
Remove the pulsecoder
If there are two wires on the pulse coder cable that are going to the inside of the motor, cut these wires leaving enough wire to reconnect to the new pulsecoder.
Remove the four screws that hold the cannon connector to the red endcap. Then remove the small ring holding the connector together.
INSTALLATION OF A NEW PULSECODER.
Fanuc Robot Programming Manual Pdf
Reinstall the connector to the red endcap and connect the overheat wires that are coming out from the inside of the motor.
Align the coupling of the pulsecoder to the motor shaft
Reinstall and tighten the allen screw inside the pulsecoder.
Align the mark on the pulsecoder mounting tab to the mark on the motor. This is very important, this is so that the control knows where the motor rotor shaft position is.
Reinstall the rubber cap on the back of the pulse coder then put back on the red endcap.
IF AN ABSOLUTE POSITION DETECTOR IS USED, YOU WILL NEED TO RESET THE PULSECODER
MEMORY. THE TWO METHODS ARE LISTED BELOW:
MANUAL REFERENCE METHOD.
On the setting page change the machine linear axis Detection units to Metric
Make parameter 1815 bit 5 a 0 for the axis to be adjusted.
Turn off/on control .
ALARM “APC ALARM : AXIS NEED ZRN” IS DISPLAYED.
Reference return the axis. Push reset to clear the alarm
Return the setting back to Inch.
PARAMETER 1815 BIT 5 IS AUTOMATICALLY CHANGED TO A ONE.
M.D.I. REFERENCE METHOD (DOGLESS ZERO RETURN)
Set Parameter 1815 bit 5 to 0 for the axis to be adjusted
Turn off/on the control
ALARM “APC ALARM : AXIS NEED ZRN” IS DISPLAYED.
Move the axis to the desired reference point by jog or by the M.P.G.
Set parameter 1815 bit 5 to a 1
Turn OFF/ON The control
NOTE:
If a softovertravel alarm occurs You will need to do the following:
For a 10 Control power on the control holding the – and . In N IPL Mode input a 4 for setting then answer NO to the question “CHECK SOFTOVERTRAVEL AT POWER ON ?”.
For a 11/12 control make the stored stroke limit of the axis in question a very large number. Example +99999999.
For a 15 control power on the control while holding the P and Cancel Keys at the same time

POSITION HAS MOVED AND ALL OFFSETS FOR THAT AXIS HAS CHANGED.
THE GRID SHIFT MAY ALSO HAVE TO BE ADJUSTED.
FANUC Series 0- Model C

Confirm device setting and parameter.
Setting screen:
ISO = 1 For FANUC Device.
I/O = 0 Set PRM No. 2 & 552 for stop bits and baudrate.
1 Set PRM No. 12 & 553 for stop bits and baudrate.
2 Set PRM No. 50 & 250 for stop bits and baudrate.
No. 38.3 Keypad type- 1 = Full keypad, 0 = standard keypad
No. 55.1 End code- 1 = ETX, 0 = CR
No. 57.4 LF or LF/CR- 1 = LF/CR, 0 = LF
Move the axis to where you think zero return should be. If you can't get to the position you would like, hold in 'P' and 'Cancel' on power up to bypass soft overtravels or you could change the soft overtravel limits to temporarily. WARNING Do not try holding in any other keys except P and Cancel. You could blow out parameters, programs or other data.
Select 'MDI' mode
Press the function key “OFFSET SETTING”
Press the soft key “SETTING”.
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 function Hard key 'SYSTEM'
Press the softkey 'PARAM'
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 4 (APZ) (make sure you count from the right starting with first space is Zero, Bits are as shown here-76543210). This will delete the current reference zero. Alarm must power down will appear, DO NOT POWER OFF
Go back to the parameter 1815 and make bit 4 a one
Power off machine for one minute and power up. New home position will be set.
Check coordinates of program and see how far you are off, if they are not correct repeat the steps. Also, make sure you handwheel the axes slowly to their overtravels. Make sure nothing binds, no servo alarms occur or destroys any way covers. If you set incorrectly, severe damage can occur. Also, remember if this is an axis that the pallet changer or Tool changer is dependant on alignment then you must check this also, because it is based off of zero return. Do not change 2nd reference position to comp for this. Always change home position.
