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
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 RS-485 COMMUNICATIONS”
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.”
