trochoidal milling with 5-axis machining

I want to use trochoidal milling with 5 Axis machining. Is this function given in Creo 5.0? I added "trochoidal_milling" in the config.pro. After selecting the trajectory milling the two parameters "trochoid_width" and "trochoid_depth appear, where i can configure my milling path. When I switch to 5-axis machining the parameters disappear. Why is this happening? I am using Creo Parametric 5.0. Thank you in advance!
