Electric control part basic fault

1. Reverse or non-rotation of spindle (possible fault at 380V voltage)

(1) reverse spindle as long as the plug plug or replace the wiring pile head can.

(2) the main axis does not turn, may be missing phase may be missing zero line, the ground line when the zero line, re-connect the power line.

2. The broken wire detection light is not on (no alarm or random alarm is given when the wire is broken)

(1) pick spring contact is not good.Readjust.

(2) broken wire detection board bad.Replacement or repair.

The signal line is broken.Check for breakage.

(4) the bottom line alarm device failure, plastic roller does not turn, plastic roller teeth fracture.Adjust repair baseline alarm device.

Electromagnet or other electrical components line leakage, interference.

3. Parking is not in place

(1) photoelectric encoder damage.Change the encoder.

(2) encoder adjustment parameters are wrong.Readjust encoder computer parameters.

The main motor fault, brake resistance is too large or too small.Adjust brake resistance.

The belt slipped.Tighten belt or replace belt.

(5) mechanical failure leads to improper parking.Troubleshoot mechanical problems.

4. The tension frame movement fails

(1) abnormal tension frame over limit.Limit switch may be damaged, may not be installed properly, reset.

(2) step drive damage, overheating, overcurrent, overpressure may cause the stepper motor does not turn, tension frame does not move.

(3) optical encoder damage resulting in tension frame disorderly go, until the frame.

(4) the computer frame parameters are not right.Adjust parameters.

5, computer display screen failure

(1) LCD damaged.Replace the LCD screen.

(2) display lamp damage.Replace the display tube.

(3) button no response.Replace the operation panel.

(4) the display screen is not bright, may be damaged 5V power supply, replace 5V power switch
