Structure of an Applied Instruction


An applied instruction is composed of an instruction name and operands.
Instruction name: An instruction name represents a function.
Operand:
An instruction name occupie one step. The number of steps an operand occupies can be two or three,
depending on the instruction used is a 16-bit instruciton or a 32-bit instruction.

Descriptions of the applied instructions
API number
1
The upper cell indicates a 16-bit instruction. If the upper cell is a dotted cell, there will be
2
no 16-bit instruction.
The lower cell indicates a 32-bit instruction. If the lower cell is a dotted cell, there is no
32-bit instruction. If there is a 32-bit instruction, D is displayed in the lower cell, e.g. API
10 DCMP.
Applied instruction name
3
If  is displayed in the upper cell, a pulse instruction is generally used.
4
The lower cell indicates a pulse instruction. If there is a pulse instruction, P is displayed in
the lower cell, e.g. API 12 MOVP.

Typing an applied instruction
Some applied instructions are composed of instruction names, e.g. BRET and SRET, but most applied
instructions are composed of instruction names and operands.
The applied instructions that a DVP-20PM series motion controller can use are assigned the instruction
numbers API 00~API 260. Besides, every applied instruction is assigned a mnemonic. For example,
