HEIDENHAIN CNC TNC620 system common fault alarm and maintenance

HEIDENHAIN CNC TNC620 system common fault alarm and maintenance.

HEIDENHAIN CNC machining center system is one of the most popular machine tool processing systems on the market today. Although the system has the advantages of high efficiency and high precision, it will inevitably encounter some failures during use. Below, we will introduce the common problems of HEIDENHAIN CNC machining center system and its maintenance methods.

1. Heidenhain controller failure.

1.There is an alarm on the operation panel, and the drive controller lights up red.

This situation indicates that there is a fault inside the controller and a software reboot is required. The steps are as follows:

1.1 Turn off all machine operation panel switches and press the "EMG STOP" emergency stop button to power off the machine.

1.2 Disconnect the power supply according to the external cut-off power on the controller.

1.3 The main power switch is suspended and all power breakers are set to "off".

1.4 Power on by pressing and holding the "X" and "Z" keys on the machine operation panel and set all power off to "ON".

1.5 Wait for the "OPN CL" button on the control panel to turn off in red, then press the key and wait for the panel light to turn green.

1.6 If the controller is still not healthy, there may be a hardware failure and the controller needs to be replaced.

Second, the center of the CNC system is faulty.

2.1 Targeting is not possible.

This situation may be caused by the feed shaft, and we can solve the problem by recalibrating the shaft.

2.2 The feed shaft is unstable.

The cause of the instability of the feed shaft may be due to the shaft's fastening screws not being tightened, in which case the problem can be fixed by checking all the screws and re-tightening.

2.3 The machine is running unstable.

This situation can be caused by system lag or interruption. The problem can be resolved by clearing the cache and restarting the machine.

3. The machine tool operation panel is faulty.

3.1 The boot panel has a black screen and no display, and you can't enter the operation interface.

This is often the result of a failure related to the power supply or cable connection. First check if the power supply is connected reliably, and then check if the cable is damaged or too long. If these causes are ruled out, it may be because the operator panel is faulty and needs to be repaired or replaced.
