Dear Sir,
Our twin turret status is as follows
1. NC switched On
2. After we ready the machine main turret starts continuously rotating
3.We put the toggle switches(behind operators panel) of both the turrets in off position and removed cap from turret declamp solenoid.
4. After doing above machine becomes ready without any alarms.
5.In Jog mode, we could move both primary axes X and Z and secondary axes X2 and Z2.
6. In reference mode both primary and secondary axes go to home properly.
7.Spindle was moved in Jod mode and there is no problem.
8.Collet operates in Jog mode.
9. When we switch to MDI mode, Feedhold lamp glows and Optional stop lamp glows(blinking) and hence no command could be executed. Same is true in auto mode.
10. We have found that only 1st Turret is used in the machine. Because Inputs and outputs of only first turret are visible. No input or output of 2nd turret is visible. May be the option bit is set Off for 2nd turret.
11.We tried to rectify turrret indexing problem , but to no avail.
We did following
we reduced speed of rotating turret
set Turret Encoder
Tried to find any clue from PLC software to find how does Turret staion match with a parameter in machine , such that it stops at that station. (Diagnostic byte 43 is used for turret bits. All bits are ok)(which byte is used to compare with byte 43 such that actual and commanded tool match?)
