Description
z The format of floating point number of Fatek-PLC follows the IEEE-754 standard. For detail explanation of the
format please refer to 5.3 (Numbering System) page 5-9.
z When operation control "EN" = 1 or "EN↑" ( P instruction) from 0 to 1, take the COS value of the angle data
specified by the S register and store the result into the register D~D+1 in floating point number format. The
valid range of the angle is from –18000 to +18000, unit in 0.01 degree.
z If the S value is not within the valid range, then the S value error flag "ERR" will be set to 1, and do not
execute the operation.
