There are various reasons why the servo motor of flange drill can't work. Today, I will analyze and discuss the common problems with you. Next, we have sorted out some materials for you, hoping to help you. Check the power supply of < br style = "none style =" none style; "> for < br style =" none style; "> (list style =" none style; ") (check the power supply of < br style =" none style; "> (none style;") (no power supply to the drive module; "/ > (4) check the air switch of servo power supply < br style =" list style type: none; "/ > 2. The control cable is not connected properly, and the coordinate axis control cable between the CNC device and the servo driver is not connected well: < br style =" list style type: none; "/ > (1) check the control cable of the setting axis < br style =" list style type: none; "/ > (2) check the encoder feedback cable and power line cable < br style =" list style type: none; "/ > 3.
