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.
