The P8-18 parameter determines the acceleration or deceleration times that will be followed for the
individual phases in the simple PLC program. In the 16-bit word, every 2-bit data corresponds to the
acc/dec time selection for the respective phase. The 2-bit data corresponds to 4 distinct Acc/Dec
times as shown in the table below.

User Manual
In the example given above, phases 4 through 7 will follow acc/dec times 0;phases 0 and 1 will follow
acc/dec times 1; phase 2 will follow time combination 2; phase 3 will follow time 3. Converting the
time selection word from binary to decimal, we get (0000000011100101)2 = (229)10, which is the
value that needs to be stored in the parameter P8-18.
