hi everyone..
I am having problem with Bridgeport VMC 760/20 heidenhain 2500 control with Siemens drive. it has a Siemens drive. When we command the machine for spindle orientation M19 the spindle starts rotating on a small speed and doesn't orient. it keeps on rotating for 2-3 min and then alarm comes,' spindle not oriented' and meanwhile spindle keeps on rotating on very low speed less than 20 rpm i think.
if after rotating spindle let's say on 1000 rpm we give M19 or tool change command spindle just try to stop and then again starts rotating at low speed and doesn't orient at all.
Main thing to note is, sometimes when we just switch on the machine, it orients. but again if we try then same condition comes.
I have checked all the parameters 1 by 1.
I have checked spindle position value in MP 4210.XX.
I have checked spindle orientation speed for spindle orientation in MP 3520.1 and it is 100.
i have checked speed orientation ramp slop value MP 3410.1 it is 1
Any help regarding this shall be appreciated....
