Hi!

I have a Leadwell VMC 40 with Meldas M50 controller. The battery is good and when we turned off the machine for 2 days, the parameters are lost.
What is the source of the problem?

I have a Leadwell MV 40 with FANUC series 18-M. Sometimes the z axis drops down when in operation, the plc shows the 401 servo error, causing the tool to collide with the workpiece manufacturing. The motor coupled to the z axis is a FANUC AC Servo Motor model: alpha 22/3000.
Someone help?

Best regards,
Edgar Henriques
