What is the problem Peter? See a recent posting on a Y axis problem with the same style of machine. If the encoder is cactus, buy a new motor. Sorry, this is the only solution I know of.

The Y-axis motor of the YM84 Series is well known for failures. The bearing between the encoder and the armature fails causing dirt to fall on the encoder wheel, hence the encoder mis-counts. If you re-Origin the machine the problem is resolved for a

The encoder on the Y axis motor is almost certainly kaput. Debris from the wear of the motor brushes or whatever else can find its way onto the encoder and give an ever increasing false pulse. The axis will start OK but progressively go out of whack

If your sure your drive lines are staying put then it must be the motor. ... odd no servo feedback alarms though. That's why I thought problem might be mechanical. Does the yv84 use servo's? IF yes, then no brushes to wrory about. Don't bother t

Hi Ken, Thank for your advice We suppose that with home position all is OK and ratio is in interval 40-60%.Y axis offset is not constant 5mm or 10mm but change ratio with working time and may be more than 10mm We think that problem is with Yservo mo

Hi, We have problem with y-axis offset at YM84 After setting the ORIGIN machine operate exactly but after sometime y-axis recieves offset bis 5-10mm.After repeated setting ORIGIN Y-coordinat became exact. The same things take place if we operate in W

A feedback error means that a particular axis did not respond by moving in a normal manner. Check the following:- 1/.. Mechanical binding. (Servo Off, then check axis moves without binding). 2/.. Check encoder plugs of that axis. Note that Philips/Ya

CSM 84 = YM84S CSM84VZ = YM84VII Generally referred to as the "Hyper" series. Model numbers went something like this - YM51VM, YM51VMII, YM53VT, YM53VTII, YM58VA, YM58VAII, YM100VP, YM100VPII, YM66S, YM84S, YM84V, YM12D. Other models were "created"

I have the part you need. The Yamaha Part number is K39-M7173-000. The same part is used on Philips machines using a different part number. This assembly is expensive because the motor is attached to a Harmonic Gearbox and encoder. I have a new unit

Hi.. Move the XY arm to the center of the machine. Turn on the servo then immediately hold “LOWER” then press “ORIGIN”. You should see the message now on the screen “DRIFT CHECK”. The arm will start to drift without an emergency condition occurr
