Common faults and solutions of CNC rebar bending center

CNC rebar bending center is a special equipment for steel bar bending. Various faults may occur due to reasons in the process of use. Below we summarize several common fault phenomena and solutions for everyone. helped.

Trouble phenomenon 1: Walking or bending does not work properly when automatic (shivering forward).

Remedy: check whether the external voltage is insufficient, the lower limit is 185V.

Fault phenomenon 2: When it is automatic, there is no response after the clamping is started after it is automatically in place.

Remedy: check whether there is a signal after pressing the foot switch of clamping start, if there is no signal, check the X27 point, check the control line or the foot switch.

Fault phenomenon 3: emergency stop alarm.

Method of exclusion:

1) Check whether the X22 point is always on.

2) Check whether the emergency stop button on the console is photographed.

3) Check the line first with a multimeter.

Fault phenomenon 4: When automatic, the walking servo alarms.

1) Elimination method: Check whether the bearing under the head box is stuck with the track.

2) Check whether the walking speed is set too fast in the production settings.

Fault phenomenon 5: The walking limit limit alarms at the same time.

Remedy: Check the line, check the X16, X17, X20, X21 points of the PLC.

Fault phenomenon 6: After the power is turned on, the bending servo alarms.

Remedy: Check whether the power cord of the bent motor is disconnected or short-circuited to ground.

Fault phenomenon 7: The servo reports encoder fault after power-on.

Method of exclusion:

1) Remove the normal encoder line and put it on the alarm servo, and manually control it. If it is invalid, it means that the driver or motor is faulty; if it is valid, it proves that the original encoder line is broken.

2) Swap the servo drive, if it is invalid, it proves that the motor is bad; if the fault goes with the drive, it proves that the drive is bad.
