What is the primary purpose of an emergency stop pushbutton?

• A. To power down the system completely
• B. To retrace the last step
• C. To stop the machine safely and quickly
• D. To enable auto-start

Answer: (C)

The main idea is safety through a rapid halt. An emergency stop pushbutton is a safety device designed to stop machine motion and de-energize the drive system as quickly as possible, bringing the equipment to a safe state. It’s built to be easily triggered in an urgent situation and typically latches off, requiring a deliberate reset before normal operation can resume. This is different from a normal shutdown or powering down, and it is not meant to enable automatic restart or to retrace steps. In short, its purpose is to stop the machine safely and quickly to protect people and equipment.
