Example: set of set-points control bit change on set-point control bit change set immediately =0 = 0/1 The travel profile is changed during an active positioning operation. Change on set point = 0 The current target position is approached with a Stop. Once the position has been reached, the new reference value is set. Change on set point = 1 The current target position is approached at the active speed. Once the current target position has been reached, the new reference value is applied without reducing the speed to zero. The gray line in the segment “Actual speed” shows the speed behaviors when the control bit “Switch at reference value” is set to 1. new set point (control bit 4) PLC t target position (set point) t Drive current target position processed t set point acknowledge (status bit 12) t target reached status bit 10 t actual speed t change on set point = 92 CM-PROFINET 0 change on set point = 1 10/13
