Sportsman issue

[ericheartsu]

I've contacted M&R and i'm waiting for a call back, but i was wondering if anyone here has seen this problem, and if there is a fix for it.

It appears we had a storm last night, as some of our computers (the ones not on back up batteries) were off this morning when we came in. Our area generally has spikes, so it's nothing uncommon. However when we turned our sportsman on, we are getting the "servo amplifier" error. We've seen it before, and typically we've been able to reset it.

However, this time around, the plate with the fork that moves back and forth on this press is stuck in the right position, as if the press was in the upwards position. We cannot get it to move, even by re-homing it. Also the fork does not engage or disengage.

Any ideas on what we can do to get this bad boy spinning?

when we had this issue, it was due to the e-stop switch being partially activated...

try to activate and de-activate estop a few times and see if that helps.

We just did a panel test, and sure enough...it did seem like it was the e-stop was partially pushed!!

thanks!

that problem seriously stumped the M&R techs for several hours...

had me go through all kinds of other testing...

finally out of desperation I smacked the estop switch, pulled it and the press started working again.

true story... back in the late 80's when a computer with a certain brand/type of hard drive (seagate ST-251 for you techies) wouldn't start up, the tried-and true method to get them running was to literally pick the chassis up, and drop it 3 or 4 inches...

I had a strange one the other day...speaking of surges.  I was letting the press cycle to warm the platens while I stacked shirts to print.  It was really dry and I walked over a touched the metal chassis on the control panel and was shocked with static.  the screen darkened a bit when it happened, but it kept on running.  No biggie, I pressed the stop button...nothing, the machine continued to cycle.  No button worked.  I had to stop it with the e-stop and shut the machine down to let it reset.  Came back up fine, but I've never had a press do that.

not shocking (pun intended), as the HMI/control panel is a separate computing device from the PLC and communicates via a separate connection.

if it got freaked out, I can see the press refusing to respond... although interesting that the print start/end and auto start/stop switches would be ignored if the HMI hast stopped responding.

Rich has mentioned this before on the M&R(not what we use).  I think the M&R's continue to cycle if the PLC has a problem while running.

Our machine will continue to work but the timer's etc will not be able to change if the HMI goes out. The mode switches should work regardless if they are properly wired to the PLC and the press will continue to operate as requested, not on its own.
