CNC plane drilling back to zero coordinate axis does not appear what is the reason, for the diagnosis and maintenance of CNC plane drill, the following small to popularize some information, hope to help you. < br style = "list style type: none;" / > the first step is to set the safety of the mechanical parts of the NC plane drill < br style = "list style type: none; "/ > 1. CNC plane drilling back expert said to check whether all parts are in a safe position, the pressing material is in the upper position, the hydraulic system is turned on, whether all safety switches are normal, and whether they are not broken out are < br style =" list style type: none; "/ > 2. Whether each axis is beyond the limit of travel. < br style = "list style type: none;" / > in the second step, check the coordinate servo parameter setting of NC plane drill < br style = "list style type: none;" / > 1. Check the reference back point mode in the coordinate axis parameters < br style = "list style type: none;" / > 2. Check the fast moving and positioning speed of the reference point in the coordinate axis parameters; "/ > in the third step, the servo driver of the NC plane drill is not enabled < br style =" list style type: none; "/ > 1. Check the output port < br style:" list style type: none; "/ > 2. Check the circuit < br style:" list style type: none; "/ > 3. Check the drive module < br style:" list style type: none; "/ > in the fourth step, the servo driver of the NC plane drill is not powered on < br style =" list style type: none; "/ > 1. Check the circuit of the NC plane drill < br style:" list style type: none; "/ > 2. Check the power module of the NC plane drill < br style:" list style type: none; "/ > 3. Check the drive module. Check the air switch of servo power supply < br style = "list style type: none;" / > Step 5, the control cable of CNC plane drill coordinate axis is open < br style = "list style type: none;" / > 4; "/ > the axis control cable between the CNC device and the servo driver is not connected or open circuit < br style = list style type: none;" / > 1. Check the axis control cable < br style: "list style type: none;" / > 2. Replace the axis control cable < br style: "list style type: none; "/ > the sixth step is to check the PLC software program of the NC plane drill, and at the same time check the PLC program < br style =" list style type: none; "/ > the above is about the reason why there is no prompt on the coordinate axis of the NC plane drill back to zero.
