Immediate Value Data Operation

Enter "0" to parameter PA2_40 (internal positioning data selection) to enable operation with
immediate value data. 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 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.)
For details, refer to "CHAPTER 13 MODBUS RTU COMMUNICATION"

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.
