Emergency stop circuit wiring example

Postby om_tech_support_JT » Tue Jun 09, 2015 10:36 am

Q: I need to set up an emergency stop circuit for your stepper motors and controls electronics in my 3D printer with a light curtain so that if the light curtain detects something like an operator's hand or debris in the work area, the motor stops immediately. Do you offer any wiring examples with regards to how to do this exactly?

A: There is no specific wiring example that would work for all emergency stop categories (ISO 13850, IEC 60204-1, EN 60204-1, NFPA 79), groups (category 0, 1, 2) and types of machines. It depends on how your machine would need to operate safely in an emergency stop situation and what safety standards/requirements you're trying to satisfy. Since we are a machine components manufacturer and not machine experts, we would rely on the expertise of the machine designer to provide an emergency stop circuit. We can offer advice as far as how to command the motor to do what you want in order to satisfy your requirements.

Here's an example of an emergency stop circuit (reference only, click for full image)*:

*Please do not use this wiring diagram for your own emergency stop circuit for your machine as we do not know what type of equipment you have.

Here's some general information I found online that explains the topic more in depth:
