Chapter 6 Applied Instructions API 1508 Symbol: S ： Source value Double word D ： Hyperbolic tangent value Double word 1. Hyperbolic tangent value=(e s -e -s )/(e s +e -s ). 2. If the conversion result is 0, SM600 is ON. Explanation: Example: 1. When X0.0 is ON, the hyperbolic tangent of the floating-point number in (D1, D0) is stored in (D11, D10). The hyperbolic tangent value in (D11, D10) is the floating-point number. Single-precision floating-point number S D 2. If the conversion result is 0, SM600 is ON. Hyperbolic tangent value Additional remark:
If the value in S exceeds the range of values which can be represented by the floating-point numbers, the instruction is not executed, SM0 is ON, and the error code in SR0 is 16#2013. 6-337 Instruction code Operand Function FTANH P S, D Hyperbolic tangent of the floating-point number Device X Y M S T C HC D L SM SR E PR K 16# “$” DF S D Pulse instruction 16-bit instruction (5-6 steps) 32-bit instruction AH500 AH500 - D1 D0 D11 D10
