Description

=

P1.1=P2.1+V1.1

Equals. Sets P1.1 to the result of the following operation

+

P1.1=P2.1+V1.1

Addition. Sets P1.1 to the sum of P2.1 and V1.1

-

P1.1=P2.1-V1.1

Subtraction. Sets P1.1 to the difference of P2.1 and V1.1

*

P1.1=P2.1*V1.1

Multiplication. Sets P1.1 to the product of P2.1 and V1.1

/

P1.1=P2.1/V1.1

Division. Sets P1.1 to the quotient of P2.1 and V1.1

U1

Sine

This function will calculate the sine of the operand.

The functions is scaled such that:

B1
X0
S1.1=U1(V1.1)
V1.1=V1.1+1
X-
END

This bank will set speed S1 to the sine of V1. V1 is then incremented. The bank is then looped indefinitely.

U2

Cosine

This function will calculate the cosine of the operand.

The functions is scaled such that:

B1
X0
S1.1=U2(V1.1)
V1.1=V1.1+1
X-
END

This bank will set speed S1 to the cosine of V1. V1 is then incremented. The bank is then looped indefinitely.

U3

Square Root

This function will calculate the square root of the operand.

The value returned by this function is an integer value. For example √7=2. For higher accuracy it is suggested to scale the solution by orders of 10.

P1.1=P2.1+U3(V1.1)

Position one is equal to position two plus the square root of variable one.

U4

Absolute Value

This function returns the absolute value (magnitude) of the operand. The returned value is an integer.

For example, U4(-25) returns 25 and U4(25) returns 25.

V2.1=-2
V1.1=U4(V2.1)

Variable one is set to the absolute value of variable two. With V2.1=-2, V1.1 becomes 2.
