Hi there,
I'm a service engineer and I have a problem with a U32 MGW-J1 wire cut machine.
The problem is with the TOUCH function.
If I try to find a hole center or a workpiece edge, the machine starts to move, searching for the edge of the workpiece. The LEDs on the servo bar are lighten on but the axis movement doesn't stop when the wire touches the workpiece. The number of LEDs lighted on the servo bar is reducing when the wire touches the workpiece, that indicates that the machine "feels" the workpiece.
If I try the TOUCH CHECK on the MACHINE OPERATE screen, it is the same. The servo LEDs are on and when touching the workpiece with the wire, the number of lighten LEDs is reducing. The touch indicator on the remote control is not on.
The machine is machining without any problem, which means that the generator is O.K.
On the EIO screen I saw that the output *TOUCH-ST is "1" when turning on the touch function.
The input *TOUCH-B is "1" when the wire is not touching the workpiece, and "0" when the wire is touching the workpiece.
Please help me to solve this problem.
Thanks
