Q: How to troubleshoot the machine when Error 10 is displayed? A: Detect the power cable with a multimeter to check the continuity of resistance. Three consistent resistance readings mean the cable is in good conduction condition. Motor-related faults may include incorrect motor zero position, abnormal rotation, burnt motor or disconnected power line. Uneven resistance values of three wires indicate phase loss fault.
 

Q: What is the correct operation to adjust the tapping chuck? A: Turn the adjusting knob counterclockwise for 3 to 4 grids until the chuck starts slipping, then rotate it clockwise for 1 grid to get the optimal clamping state. If slipping happens when processing laser holes which usually feature high hardness, select taps specially for high-hardness material and tighten the chuck a little more.
 

Q: What are the specifications and working principle of the 5-pair pole servo motor? A: This 1200W servo motor works under 50-60HZ and serves as the drive component of tapping machines.
