7.1.3.7 Arithmetic operation (Statement)

The PR mode has arithmetic operations commands, including addition, subtraction,

multiplication, division, AND, OR, MOD, and logic conditions. The available operands are user

variables, parameters, data arrays, monitoring variables, and constants. Among them, the user

variable is the register only for arithmetic operations. There are 64 sets of user variables, with a

data size of 32 bits. The data size of a constant is also 32-bits. After all arithmetic operation

commands are executed, you can set a jump condition in the path so that execution jumps to

different PR path and then continues or stops once the operation is done. You can also use it as

a loop function. The arithmetic operation commands support negative integer operations but not

floating point operations. Negative integer operations are calculated by “two’s complement”.

Figure 7.1.3.7.1 is the Arithmetic Operations screen in ASDA-Soft. Arithmetic operations must

be created in ASDA-Soft. To avoid errors, do not use the servo panel or RS-485 for arithmetic

operations. Once you complete the arithmetic operation, click Download All PR to write all PR

paths to the servo drive.
