\r\n Powerpath 15 threading problem\r\n
\r\n \r\n \r\n \r\n
\r\n
\r\n
\r\n The thread pitch is off on my machine, about .025 inch per inch of thread with a 16 tpi.
\r\nI have noticed that the rpm reported is around 12-15% off of the rpm commanded, ie. 144 reported with 150 commanded when showing 100% spindle speed.
\r\nI\'m guessing the problem is either with the encoder not reporting the correct rpm or the spindle drive not setting the correct rpm.
\r\nHas anyone else seen this? Anyone know how enter a correction for rpm?
\r\nI\'m looking for a contact rpm gauge to check the actual spindle rpm.\r\n

\r\n ahhh...you to have a psychopath 15 too.LOL I have not had that problem with my machine luckily. I wonder if you have some weird following error in the Z axis or something? Have you tried threading at a slower or different RPM to see if it helped? Go to the maintence page and check the following error (next to Z axis position on the DRO). You would think the control PID loop would be smart enough to increase the spindle RPM single to the drive to get to the commanded RPM. Let us know what you figure out.
\r\n
\r\nIm doing some work to my machine right now.....Doing a servo and drive retrofit to the new yaskawa sigma 5 system. Repairs on those old CACR drives are way too expensive and they are always band-aid fixes. around 1400 to fix one drive. I have sourced sigma 5 drives and servos that are equivalent replacements for $2400 for everything brand new with the cables. get another 20 years out of the lathe.....lets just hope the BMDC does not die.
\r\n
\r\nLet me know if you need a brand new industrial motherboard for you powerpath. I have some new ones i got from a bridgeport tech....the make the control run faster and its a nice upgrade....and WAY cheaper than EMI.\r\n

\r\nIm glad you got your spindle RPM figured out...thanks for posting that, its good info. I spend 3 hours on the net running down the stupid connectors i need to hook the new drives to the AXSBOB. PM me if you need the part numbers...they were a mother to find.\r\n

\r\nHELLO I\'M OMAR
\r\n
\r\nI AM WRITING TO YOU FROM THE DOMINICAN REPUBLIC
\r\nI HAVE A PROBLEM ON A Bridgeport/Romi PowerPath 15 CNC LATHE
\r\nTHE ESPINDEL MOTOR BURNED, WE REPAIRED IT, SEND IT TO REWIND.
\r\n
\r\nAT THE MOMENT OF TURNING ON IT TURNS FOR A FEW MOMENTS AND THEN IT TURNS OFF AND SAYS THE FOLLOWING MESSAGE
\r\n
\r\n "SPINDLE NOT AT CORRECT SPEED"
\r\nBUT ON THE SCREEN IT IS SHOWING THAT THE SPEED WE CONFIGURED IS EXACTLY AT THE ONE IT HAS WHILE IT WORKS BUT IT STILL TURNS OFF AND SHOWS THAT ALARM.
\r\n
\r\nI WOULD LIKE TO KNOW WHAT IS THAT PARAMETER 71 WHICH YOU MODIFIED, MAYBE IT WILL HELP ME.
\r\n
\r\nTHANKS IN ADVANCE\r\n

For an example I installed this Dell 15" monitor in mine. There was a little filing in the lower right corner to allow access to the controls. This probably was not necessary since the monitor comes on when the machine starts and I have never had to adjust the brightness etc. I made some sort of crude bracket in the back to hold it in place if I remember correctly. Its been a while and it has always worked well. The monitor has 2 model numbers listed on the back; E156FP or E157FP.

Nice mod..I didnt mill a notch in the front plate. My monitor always turns on with machine and never needs adjusting. I think i put the buttons on the back of the monitor. I made a new mounting frame out of angle aluminum and put a piece of clear lexan in front of the lcd panel. Took lots of time but its nice.

\r\n Now I\'m getting the "chuck not clamped" alarm at random. I have watched the chuck clamp sensor during the run and
\nthe light on the sensor is on before and after it sets the alarm and stops the machine. It\'s doing it with or without material
\nin the chuck. I don\'t think it could be the proximity sensor since the light is on. I can start the program again and it will run
\nwithout changing anything.

\r\n I remember having to adjust my sensors when i first bought the machine. By the looks of it one of mine was replaced at one time. There should be two sensors....one for each direction the draw tube move (forwards and backwards) . I have seen prox switches not work even though the light is on...not all that common but it happens. The 1st thing you need to do is go into the maintenance page and see if they are turning on or off. After that i suspect you have a bad switch or maybe something wrong in your wiring. Your computer power supply might be failing also. I just replaced mine with an ATX one. It made a difference....before i changed mine the three circuit boards in the bottom of the control panel were all different brightness-es...after i changed the power supply they are all the same. Its a sign it was getting weak.
\n
\nIf you lived close buy i would come help you for free. Im in southwestern michigan. These psycopath lathes are good machines but can be a pain in the ass sometimes.LOL Mine holds size great.....+- .0001 all day once you get it warmed up.
\n
\nLet me know what you figure out..........I always like the hear about these lathes.\r\n

\r\n I added the chuck clamped I/O to the viewing box and monitored it while the spindle ran. I noticed it was flashing "OFF" and back on immediately. Enough to trip the control
\nto shut-down. The light on the sensor always stayed on.
\nI replaced the Telemecanique XS1-D12PA140 chuck clamp proximity sensor with a XS1-M12PA370. Same fit and function, a bit longer case.
\nI ran the spindle for about 20 min.. It seems to have fixed the problem.\r\n

Powerpath 15 threading problem
The thread pitch is off on my machine, about .025 inch per inch of thread with a 16 tpi.
I have noticed that the rpm reported is around 12-15% off of the rpm commanded, ie. 144 reported with 150 commanded when showing 100% spindle speed.
I'm guessing the problem is either with the encoder not reporting the correct rpm or the spindle drive not setting the correct rpm.
Has anyone else seen this? Anyone know how enter a correction for rpm?
I'm looking for a contact rpm gauge to check the actual spindle rpm.
