​Stopping Travel and Stopping Time (Safety Critical)

Shutdown category: STOP   0 (category 0 cuts off the drive, locks the brake); STOP   1 (Category 1 path controlled deceleration stop).

Assessment objects A1/A2/A3; The stopping stroke of multi axis compound motion will increase.

The STOP0 value serves as a reference for testing and simulation; The brake wears out with the number of STOP0 triggers; Require annual on-site testing to stop travel.

Project Planning

Planning risk warning: Long term temperature limit operation, high-frequency short cycle reciprocating, static loading, external process forces will accelerate component wear, and maintenance cycles need to be shortened. If necessary, consult KUKA. Automatic shutdown protection for over limit robots.
