Hello,

We have a Sodick K1CN small hole EDM machine, with a Fujitsu FM77AV40SX control.
We don't use it too often, last time it wasn't turned on for a month.
Last week I wanted to use it, but when I tried to measure the workpiece, I noticed that the contact doesn't work. So the electrode doesn't stop when it contacts the part. I've been examining it for a week, but no success. There isn't any voltage between the electrode and the work table (between P3 and P4). Could somebody tell me, how many Volts should it be? Any idea or suggestion would be very great.

Kind regards,
Gábor
 
Hello,

Problem solved. The -15V output of the power supply labeled "T1" was faulty. I changed the device and now it works.

Regards,
Gábor
