E-STOP

Hardware

The AutomatePro features an onboard E-STOP input, allowing it to read the state of an external E-STOP. While the E-STOP state disables the Digital Drives, its primary function is as an input and it has not been designed to meet any functional safety standards.

The E-STOP input is located on Pin A5 (main connector A) and requires an input voltage ranging from 5-24VDC. If the E-STOP pin does not need to be sensed, it must be connected to the onboard 12V_IO supply.

Software Interface

E-STOP is a hardware function: the E_STOP signal gates the digital-drive drivers directly.

• Release E-STOP:

  gpioset --mode=exit gpiochip0 102=1

• Read E-STOP status:

  gpioget gpiochip1 25

  Returns 1 when engaged and 0 when released.
