    If 2 safely limited speed functions are active at the same time, the function with the lowest speed limit has higher priority than the function with higher speed limit. If 2 equal safety functions have to be configured, they must be parameterized as SS1-a and SS1-b, or as SLS-a and SLS.b. 16 | Danfoss A/S © 2018.09 AQ279747441421en-000101 / 130R0292...
