Run into a new problem with my ”new” Feeler / Meldas 520AM VMC:
When I have the machine in Manual mode and I want to orient the spindle (rotate it to the tool change position), most of the times it will not orient properly. It starts to rotate fast but then slows down to really slow creep before it stops at the orient point. When I grab the spindle when oriented it is possible to move it a little back and forth (spongy feeling) before it gets stiffer.
My other Feeler orients much quicker and does not allow any spongy moves after oriented. It is quite stiff when oriented.
Does anyone know which parameters that affect the spindle orientation?
I have checked the cable from Magnet Sensor and Spindle drive’s CN6 port and it was OK.
I have also checked the cable from Spindle motor’s built in Pulse Signal Generator and Spindle drive’s CN5 port and it was OK.
Maybe it is an encoder problem, a magnet sensor problem or parameter problem?
The machine has produced a lot, so maybe the parameters worked OK and lately some encoder or magnet sensor problem has occurred?
What do you think?
This is the kind of orientation setup I have on both machines.
On the newer (1998) Feeler FV-800A with the orientation problem there is a SJ-N 7.5A Spindle motor.
On my older (1996) Feeler FV-800 with working orientation there is a SJ-7.5XW8 spindle motor.
Should some parameters differ due to the different motors used?
