The device consists of a button fitted below the display of the machine, which is composed by 2 NC
micro switches connected in series. On the same button is connected a rope: if pulled act exactly as

rope, the NC contact is opened then the CPU/ARM board realize about the emergency status.
3.16.1. C
ONTROL LOGIC
The control block diagram is as follows:
When the user press the emergency stop device, the NC contacts is opened, changing the state of the
two signals output by them to the CPU. Each of the two micro switch outputs a distinct signal,
interpreted as follows: one is an "SW Emergency" signal, and one is an "HW Emergency" signal.
The two signals are managed as follows:
SW Emergency: The CPU board detects the emergency condition and signals it by
displaying the message "Reposition the emergency stop device and touch the screen" and
sends the information to the drive over the 485 serial link to halt the motors..
HW Emergency: The CPU board sends the emergency signal directly to the drive to halt
the motors.
To reinstate the machine's operation, it is necessary to reposition the emergency stop device on the
control panel and press any key on the display, as prompted.
