Functions may be combined with mathematical expressions. The order of execution of mathematical expressions is from left to right and can be over-ridden by using parentheses.

Instruction

Interpretation

V1=@ABS[V7]

The variable, V1, is equal to the absolute value of variable V7.

V2=5*@SIN[POS]

The variable, V2, is equal to five times the sine of the variable,

 

POS.

V3=@IN[1]

The variable, V3, is equal to the digital value of input 1.

V4=2*(5+@AN[5])

The variable, V4, is equal to the value of analog input 5 plus 5,

 

then multiplied by 2.

Variables

For applications that require a parameter that is variable, the DMC-3425 provides 126 variables. These variables can be numbers or strings. A program can be written in which certain parameters, such as position or speed, are defined as variables. The variables can later be assigned by the operator or determined by program calculations. For example, a cut-to-length application may require that a cut length be variable.

Instruction

Interpretation

PR POSA

Assigns variable POSA to PR command

JG RPMB70

Assigns variable RPMB multiplied by 70 to JG command.
