DMTG 6150 CNC Lathe User:

Dear CNCmakers, we have a DMTG lathe machine with GSK980TDb CNC system, we upgraded the manual speed change to inverter 2 grade speed change, but when we insert M41, M42 or M43 command to the CNC program, the GSK980TDb says they are illegal command, and parameter K15 for automatic shift is empty, what shall we do?

CNCmakers Support:

The No.1 parameter should select inverter function as invalid.
