CHAPTER 3 OPERATION

3.4.11 Immediate Value Data Operation

To enable operation with immediate value data, enter “0” to parameter PA2_40 (internal positioning

data selection), or enter "1" to that parameter and "3" (immediate value data operation) to parameter

PA2_41 (sequential start selection). Point-to-point (PTP) positioning operation is made according to

commands sent via RS-485 communications. When In-position [INP] is active, enter desired

positioning data and so on and turn start positioning [START] on (activating edge) to execute

3

positioning.

To enable immediate value data operation, you can allocate “77” (positioning data selection) to a CONT

signal and turn the signal off. Use the Modbus-RTU protocol. (Immediate value data operation is

impossible with the PC Loader protocol.)

To perform immediate value data operation with the Modbus-RTU protocol in a system

consisting of two or more servo system axes, you can use broadcasting to start multiple

axes simultaneously, so that pseudo interpolation operation is realized.

For details, refer to “CHAPTER 13 RS-485 COMMUNICATIONS.”
