Electrical Hardware:
The safety loop adopts dual loop redundancy design, and the signal source type is test pulse.
The signal output by the safety relays S11 and S21 first passes through the WD signal of the controller
(commonly known as "watchdog"; this signal is disconnected when the controller has an error, and the
emergency stop is triggered). Then passes through the teach pendant emergency stop double circuit, and
series the emergency stop on the panel of the electric cabinet, the user emergency stop, and finally the
circuit returns to the safety relay S12, S22 to realize the control of the safety circuit.
The output adopts a dual-circuit design that takes into account both hardware and software. In terms of
hardware, the safety relay output controls the servo drive STO. When an emergency stop is photographed,
the STO signal is directly cut off, an emergency stop instruction is issued to make the robot stop urgently,
and the motor brake is closed at the same time.

Software:
In terms of software control, the emergency stop button will receive emg1 and emg2 double-loop
signals when pressing the safety board, and any action will trigger the emergency stop signal. The
dual-loop watch dog communicates with the robot controller. When an error occurs in the robot software,
the watch dog (equivalent to a normally closed contact) is disconnected, and the robot will stop
immediately.
