Hi, our company looks for a new smt mounter, we need a low-medium production machine with a real cph around 22000, the option of jedec tray and a range of component 0402-2010. Thanks to everyone in advance.

Hi Ringel, There's lots that fit that range, but a great deal depends on the support in your location, budget, number of changeovers, number of component types (feeder positions required) how many shifts you plan on running, future expansion plans e

What is the (initial position) ratio of pulse counts to home encoder pulse (relative to the home sensor). It should be 50% +/- 15% Run this test several times in between a warm up. I bet your numbers are all over the place. I bet you have a loos

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

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

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

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

sorry. re-read your post. The problem is the home sensor relative to the home pulse. You're catching the wrong home pulse. a 10mm offset sounds about right for a 360 degree error. You need 50% +/- 15 % to ensure you always zero to the same phys
