External Trip Input Activated

What does Ext Trip mean?

This fault indicates that a digital input configured as an 'External Trip' has been activated, signaling that an external safety device or interlock has detected an abnormal condition. This is a generic trip initiated by an external system. The specific cause depends on what the external input monitors. It functions to prevent the drive from operating under unsafe external conditions, safeguarding both personnel and equipment.
