Hi, here is a manual for the FC1 , dont think motoman will mind this being posted , its redundant .

Hi , send me a PM with your email address , if Roboprof can't find it , besides the manual ,
setup information can't be posted openly as codes & FD parameters need to be used and altered.

Hi , as previously said ,
Sent me your email address via a PM

Hi , you have reported this post to the moderator as "Important".
Please note that response to this Forum is by experienced Engineers , they do this"Voluntarily".
Here is more detail for your request-
As previously mentioned you need to be in Expanded Language - Cust. > Lang. (F1) then select Expanded.
Next . teach your position [MOVL] >> Use the East button on the (north,south,east,west) Cursor
so you high-lite the right side of the MOVL line.
Press EDIT
Press F1 (should read "Line Edit")
Press the Up Arrow , the top line is high-lited , UNTIL should be above F3 , then Press F3.
Press F1 (should read Const) [this selection is for constants and not variables].
Press F1 (should read Const)
Select "on " or "off".
"Enter".
line should be updated .
Press West cursor to move high-lite back to Left side.

If grease has been forced though the motor to contaminate the brake , I think the brake slipping would be the least of ones problems

Hi , yes by all means , make sure it's ok before using it , these larger robots usually have a hard life due to their applications .
If it's from the the same model and axis number , you might consider leaving the spline gear on the the servo motor and just bolt it in after correct alinement.

Hi , and now ?
If you are asking what now?
You need to contact Motoman and purchase a new or refurbished servo motor.
The brake is inter-grated and encoder and motor must also be dismantled to refurbish the brake.
Becareful if you buy a refurbished motor make sure it has been serviced by Motoman and not a backyard mechanic.

Hi , if your display doesn't show which axis , then drive the robot to a point and look in the robot pulse position display take a note of the encoder pulse numbers , then hit emergency stop , wait several minutes , check the robot position encoder numbers again and see if a encoder value has altered as you turn servo power Back on, a couple of pulses is normal but shouldn't be 3+ .

Hi,
the Stop circuit is dual , one set of contacts allows "Servo power On" , the other is "Servo Enable"
which is the Contractor / Relay (base of cabinet , right hand side) . This contractor must be pulled in.
Note - because the Servo Power circuit might be OK , you will have no error display.
Check that BOTH wiring circuits are OK and no broken wires and bad contacts etc. are present.

Hi , the Drop Value is a derived encoder difference between the last power "Off" position ,of the robot arm, and the position the arm is in when you turned the power back "On". If the predetermined number is exceeded the controller will shut down and throw this alarm up.This is not a Major alarm.
If you have a servo motor which has bad braking and the robot arm slowly moves ( Gravity) whilst the servo power is "Off" you will have this situation .
Check the brakes are OK.
Note - if this robot arm has had many "Emergency Stops" ,while moving at high speeds, you can wear the servo-motors brake efficiency down.

Hi , see attached & have fun , however, ERC should be scraped .It still surprises me that there are some still operational.

Hi , you can disconnect the hardware via a plug within the TP.
Note - to shift the cursor around the screen press the [area] key
Along with the [ north . south . east . west ] keys.

Hi , possible alternative to already suggested options.
the standard XRC welding control PCB is the XEW analogue board ( the MEW is for the MRC) .
However, some digital welders can be setup with preset welding files that are selected from external device such as a PLC OR , robot controller such as ERC - MRC - XRC - NX etc.
You can use the standard CNC general purpose I/O connections (ie. XRC : CN10 ) or connect via general purpose interface (24volt coil) relays purchased from Internet or local electrical wholesaler, this gives you control voltage , XRC / Welder ,isolation.
Then write simple Welder file jobs that select those files - use another output ? within the job to turn ON the welder - plus WAIT for an Input ? ARC Established from the welder if available.
Write a welder OFF job that selects a Crater Fill file with timer and turn OFF the welder.
When you require these welder jobs simply use the CALL JOB instruction within your programs.
It's been my experience that most welding robots would Only use about 6x welding conditions at most,
So you could have 6x of these Welder ON jobs with possibly 1x Welder OFF job.
Please note - some digital welders also use binary to select these preset welding files AND you can set the XRC general purpose outputs in Binary , this means with 4x wires you can select ( 1-2-4-8 ) 15x output selections/conditions.
Hope this helps.

Hi , yes !
this model is well past its " boat mooring" date, however , see attachments & have fun.

Hi , I don't think we have seen a post like this with so much feeling unsaid

Post which included Fanuc Manual has been removed , please see Fanuc Forum posting Conditions.

Hi , if you look in the "XRC Instructions " manual for the controller , ( note there is also an "instructions " manual for the arm ) you will see ( section 4 ) how to modify XRC to add I/O and other boards, also additional base & station axis.
You should be able to work out what you will need to re- Initalize it back , as far as removing hardware , there is only so much you can explain here.

Hi , reply to your concerns, you are not breaking any rules with multiple postings , you are a hero for trying to help someone else.

Hi , when posting questions like this you need to give model of machine .ie.
MRC , XRC , NX 100 , DX100 or DX200.
And model of Arm is also helpful .

Hi ,
if your not sure of the correct procedure
then Pay for a Motoman Service Engineer.
You might need them to source a new part anyway.
