#127500 - not life and limb Responding to: ???'s previous message |
Emergency stop should act directly on the power lines, bypassing the mcu and stuff.
YES, YES, if the emergency may affect life and limb. but the emergency I referred to was an emergency stop of an industrial knitting machine to activate when it screwed up. A 10 ms delay had no effect but 1000 more threads to fish out before restart. Pulling power would have made it MUCH worse. Erik |
