Hi I’m not sure if you can , however, you could try offline using Notepad and watch your syntax.
On another point ,looking at your T values . Please remember what T ime value is used for .
In the Arcon , it’s used for arc established before robot moving , if your welder <>Robot interface has arc established feedback ( most do) then this timer could be for gas purge being More suitable for SS & Alum.
In the Arcof , it’s main use is Burnback ( crater-fill) to achieve the correct wire stick out from your Arcof , so it’s correct for the next Arcon.
Now for the main point in my reply , Timers are usually used as an interface to Mechanical response ie. electrical signals <> mech. Movement.
With most all Mig - Mag - C02 welders and their wirefeeders , Not a lot happens in 0.1 of a second. For any thing meaningful to take place the rule of thumb is 0.3 sec. this will allow wire feed motor and welder circuitry to respond. If this causes problems then alter the values of Amps & Volts.
If you are doubting this 0.3 sec. look at the default values in your CIO Pulse commands , they are usually 0.3 , this gives Relays , gas & air solenoids time to react to electrical pulse signals.
So in conclusion- if your welder has arc-estab. feedback and your welding M/s then forget the T imer value.
If you are not having Arcof burnback problems just Use “Arcof “ command and forget any values. Or , if you are having
wire stick out problems (to long) and your burning tips (to short) then use “0.3” and play around with Amp & Volt values.
Typical values using 1.2mm wire on M/s Arcon file @ 280a - 23v>24v then Arcof file will be in the region of 130a - 17v - 0.3sec. Please note the Arcof values can be used on many differing Arcon values, as the same result (stick out) is required for the same sized Welding wire.
This is to achieve wire stick out of 10mm , perfect for the next Arcon .
Hope this is helpful .

Hi , it is frustrating sifting through the cobwebs ,
the MRC was great for the Soft Tree at rear of Manual, its a great memory prompt.
see attached.

Hi & wellcome,
Go to - Motoman.com. > Support > Documentation > fill in the required field boxes >
And Wollarr ! hunt through the manuals listed.

Hi , weldsplatter ! the bane of many welders lives !
Caused by a multitude of issues
* your accountant has found a cheaper welding wire .
* some body has opened that big door next to the system and shielding gas is now suspect.
* accountant has found a cheaper source of base material and cheaper steel is now part of the manufacturing component process.
* mains voltage is suspect at certain times of the day as load goes up and voltage (heat) goes down.
Following Unlikely but look any way .
* shielding gas mixture is suspect.
* welder connections (earth) are suspect .
* m/s has rolled mill scale and not clean ( note - pure Co2 shielding gas is blamed for splatter in many venues ,however, clean / rumbled / pickled m/s has reduced splatter even with Co2)

Hi , ooopppsss
I misread your reply , the S doesn’t work with L wiring , my apologies,
It would appear your S motor / encoder is faulty , have it checked by reliable source .
To look at repairing the brake you need to dismantle the motor-encoder , it’s just not worth it .
It’s normal to replace the complete unit. Be careful where you source the refurbished unit from,
There are Many back yard techs around.

Hi , you don’t say what your XRC controller power supply is - however.
If it’s Japanese supply then it’s 3x phase 210volts +/- 10% @ 1kw.
If it’s fitted with transformer for -
- Europe - 3x phase 385v >> 210 volts +/- 10% @ 1kw.
- North America - 3x phase xxxxx >> 210 volts +/- 10% @ 1kw.
Etc etc.
Although documentation might say 1.5kw or 2kw , you can quite successfully use 1 kw
Supply as very seldom will the load ever exceed 1 kw unless it’s fitted with extra Servo’s
and even then most transformers will take % over current for reasonable periods of time.
Cable supply size will depend on your country’s regulations , however, 2.5 mm 3x phase +E
as a “minimum” should suffice .
Hope this helps

Hi , see attached , ERC are very , very , very OLD tech.
so have fun.

Hi Rzapo, what part ERC controller or the Arm ?

Hi , it's standard practice to swap over servo motors of similar size to see if a fault goes with the servo motor/encoder.
I'm not sure why you are concerned about the brake wires as these Servo motor/ encoders are on plugs and wiring shouldn't need to be of concern , simply unplug both motor/encoders and swap.
Please also remember you will need to re-record the home origin on encoders.
This inconvenience is a small price to pay to confirm if it's not the Servo motor/encoder.

Hi , please see attachment. (If you want the complete manual , send me a PM with your email address)
shown is the internal wiring harness and wiring of the EA1400N
On last page you will see S-axis , 3CN-1 showing all the motor connections .
if you cannot define the pins due to damaged wires.
These can be defined using a Simple Multi-meter on Ohms scale Pins 5 BA2 & 6 BB2 (unplug before measuring)
which are the Brake [YB] wires. There should be no circuit to other wiring, other than each other.
Most all standard SGMRS robot motors will be of similar configuration.
Please remember that the clearance on the Brake disc's is very small and if to much brake wear is
present the magnetic brake might not release. If this is the case you should contact Motoman for a
complete Motor/encoder replacement.
Hope this Helps.

Hi , please clarify what model robot you are dealing with , SGMRS can mean NX100 , however , Motoman are a bugger for mixing things up.

Hi , this is an issue with NX100's , the internal main Unit has two fans mounted one above the other , why engineers mounted them this way is any ones guess, however, the PCB below the fans has a sensor on it to detect temp.
Unfortunately this sensor can go out of spec. And give false alarms. Not a lot you can do. There is a number of parameter settings for fans faults , somebody on this forum might know if changing parameter settings helps, I haven't found one yet.
Please remember that Motoman have two types of fans , 2 wire ( simple and unmonitored) and three wire ( monitored ) so don't think a cheaper two wire can replace a three wire.

Hi , see attached the basic MRC instructions set showing the external circuits etc
hope it helps.

Hi , a series of circular weld passes , see attached "extreme" case drawing (3.5x passes). Number of Passes & weld values depend on size of
the hole , @ 12mm you may need to have a copper back plate and get away with just 1>1.5x passes.

Hi, If your ever at a loss with welding robots , just remember that a robot is duplicating what is done by hand.
Pickup a manual Mig/Mag torch and work out the best method. In this case its ever decreasing circular weld passes.
Ask a manual welder how he (or She) would do it , its the same process.
hope this helps.

Hi & welcome , your machine may need to be re-initalized to new hardware format .ie. If Extra axis removed . This procedure needs be carried out using Yaskawa security level.
If your machine has been fitted with station isolation relay hard/software, this may also be an option , you should contact Yaskawa.

Hi , there are two batteries in the controller , one for systems and one for encoder ( with encoder backup. In base of robot as well). hope you had the power on the MRC when you pulled out the systems battery to measure voltage.
Otherwise yourve probably lost systems data and will need to reload or reinitalize.
Servo power will not come on unless all systems are correct , if you have corrupted Parameter then any thing could be wrong as well.

Hi , following the Alarm 200 , there should be a ( parameter) mentioned .
This group a parameters should be initalized as corruption or somebody has modified incorrectly.
Note. When initalizing anything you need to be sure what your doing , it cannot be done without correct security code and procedure. If you have a full backup you can always reload the parts required.
Are the system backup batteries ok. If machine has been in storage for years batteries will need to be replaced and possibly a complete Initalize carried out.
MRC is old now with Motoman not supporting this model.

Hi, if you have a MEW01/02 board installed , its a handy way of controlling plasma,tig and other machines .
If you initialize MRC as a welder you have the Arcon - Arcoff features on the TP for quick means of control.
If you haven't access to MEW01 PCB then Yes, simply use the Digital Outputs to control external machines , interface with a relay to achieve isolation , its not a good idea to mix power supplies.
If you don't have Instructions manual for MRC , which shows all the I/O , let me know & ill send it .

Hi , here's another manual , had trouble uploading due to size.
Motoman shouldn't complain as they don,t support MRC anymore
