    Low level width not less than 7.5µs. 11. Protection Functions To improve reliability, the Drive incorporates some built-in protection functions. The DM422C uses one RED LED to indicate what protection has been activated. The periodic time of RED is 3 s (seconds), and how many times the RED turns on indicates what protection has been activated.
