■About the communication start with servo amplifier
Communication with servo amplifier is valid when following conditions are realized together.
• The power of Simple Motion module and servo amplifier is turned ON.
• The servo network composition parameter "[Pr.100] Connected device" in the buffer memory of the Simple Motion module
is set with a value other than "0".
When the power is turned ON or the CPU module is reset, the data stored in the flash ROM/internal memory (nonvolatile) is
transmitted to the buffer memory/internal memory.
Therefore, when the servo network composition parameter "[Pr.100] Connected device" stored in the internal memory
(nonvolatile) is set with a value other than "0" and the module is started up in order of the servo amplifier and the Simple
Motion module (even before the RUN LED of the CPU module is turned ON), the communication with the servo amplifier is
started and the servo parameter stored in the internal memory (nonvolatile) is transmitted to the servo amplifier.
■How to transfer the servo parameter setup from the program/engineering tool to the servo
amplifier
The servo series of servo network composition parameter "[Pr.100] Connected device" inside the internal memory
(nonvolatile) set to "0". (Initial value: "0")
The setting value of the parameters that correspond to the servo network composition parameter "[Pr.100] Connected device"
inside the internal memory (nonvolatile) becomes valid when the power is turned ON or the CPU module is reset, after the
communication with servo amplifier is not started.
However, the PLC READY signal [Y0] is changed from OFF to ON after setting the servo network composition parameters
("[Pr.100] Connected device": except for 0) with the program/engineering tool the communication with servo amplifier starts.
■How to transfer the servo parameter which wrote it in the internal memory (nonvolatile) to
servo amplifier
Flash ROM writing carried out after the servo parameter is set up in the buffer memory/internal memory.
After that, when the power is turned ON or the CPU module is reset, the servo parameters stored in the internal memory
(nonvolatile) is transmitted to the buffer memory/internal memory.
When the servo parameter is written in the internal memory (nonvolatile), it is unnecessary to use a setup from the program/
engineering tool.
