The machine has forgotten the reference point, what can I do?
Machines have reference reminder procedures depending on control units, for example a machine with Fanuc control. Firstly, It gives the 306 Battery voltage low alarm, and after the battery voltage decreases, 300 APC switches to Need ZRN error and informs that the reference should be reminded. The following steps should be followed in order to eliminate this problem.
First of all, the battery of the machine is changed.
The relevant axis is moved manually to the reference position (Depending on the brand model of the machines, there is a mutual arrow),
Press the Off-Set key on the keyboard,
Press the Setting button from the bottom of the screen,
On the screen Parameter Write:…. Section, type 1 and press the Input key,
Press the SYSTEM key on the keyboard (the parameter page will open),
By typing 1815, No SRH button is pressed from the bottom of the screen,
APC and APZ columns are set as 1 by accessing the relevant axis row and the machine is turned off and turned on again by using the main switch.

The machine gives an Emergency Stop alarm. What can I do?
This alarm is usually caused by forgetting the emergency stop button pressed, which we call the Emergency Stop button on the machines.
Furthermore, depending on the brand and model of the machine, EMG switches that enable stopping in cases of limit excess on the axes may be pressed. In this case, the problem can be solved by moving the axis to the opposite direction with the switch recovery key that enables the axis to move.
