If the integral value Y < -32768, H8000 is stored in Y, H0000 is stored in YR, and the execution output is switched ON. 228 PROSEC T SERIES Results of integral calculation Y (integral value) X D0777 ­10 10 ­23 ­5 5 5 5 M RW010 3 3 3 3 3 3 N RW011 10 10 10 10 10 10 Y RW020 ­43 83 67 83 66 50 YR RW021 ­2 ­1 ­1 0 1 2 0 80 Initial value First calculation Second calculation Third calculation Fifth calculation Sixth calculation Fourth calculation Number of calculations 0 ­50 3 10 ­10 * If N or X is 0, the integral value Y and the value of the remainder YR do not change, but the execution output goes ON. * When this instruction is executed, please ensure that the value of YR (the initial value before execution) is such that -M < YR < M. This depends on the values of Y and YR being calculated by the following procedure. Here, |N|·X a = ­­­­­­ |M| As can be seen from this procedure, if the integral value of the remainder, | YR |, is greater than the divisor | M |, +1 (or -1) is added to the integral value Y, and processing is executed in such a way that | YR | < | M|. Accordingly, to obtain the initially held integral value Y, -M < YR < M must hold true (| integral value of remainder | is smaller than divisor | M |). Instruction Set 229 RAMP FUNCTION FUN169 Ramp Function (RAMP) Executes ramp function calculation. Related Instructions Input Completion output Function * The ramp function calculation is executed repeatedly as outlined below, on Input Action Output the basis of the mode/rate M and the rate N stored in the 2 consecutive registers starting with the operand B. Each scan a calculation finishes, and OFF no execution OFF the contents of the 5 consecutive registers starting with the operand C are execution: Not completed OFF updated(present value P, present value remainder Pr, increase K, increase ON remainder Kr and target value Sx). If the present value P reaches the execution: Completed ON target value S specified by the operand A, the calculation is completed, and the completion output is switched ON. * The data range of each operand is from -32768 to 32767. * There are 2 modes of calculation, the rate specification mode and the scan specification mode. In the rate specification mode, the approaching rate (increment) to the target is specified by |N|/M. On the other hand, in the scan specification mode, the calculation times to reach to the target is specified by N. The mode is selected by the data of M; M>0. . . scan specification mode Operand opr B C A name X Y Device (for digit specification) T3 only S L R Z T.

In the same way, the increase remainder Kr is added to the present value remainder PrO, the result is stored in RW058, and the completion output is switched OFF. This calculation is repeated, and when the present value P has reached the target value S (contents of register D0123: 10000), the completion output is switched ON.
