Chapter 7 Memory Configuration and Data Process
How to transfer the servo parameter setup from sequence
program/GX Works2 to the servo amplifier
The servo series of servo parameter "[Pr.100] Servo series" inside the internal
memory (nonvolatile) set to "0". (Initial value: "0")
The setting value of the parameters that correspond to the servo parameter
"[Pr.100] Servo series" inside the internal memory (nonvolatile) becomes valid
when the power is turned ON or the PLC CPU 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 parameters ("[Pr.100] Servo series": except for 0) with sequence
program/GX Woroks2 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 PLC CPU 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 sequence program/GX Works2.
Servo parameter of the buffer memory/internal memory
The followings show details about the operation timing and details at transmitting
the servo parameter of the buffer memory/internal memory.
POINT
(1) When the servo parameter is written in the internal memory (nonvolatile), it is
unnecessary to use a setup from the sequence program/GX Works2.
(2) Axis connection time varies depending on the number of axes and the servo
amplifier's power supply ON timing. And, time when "20: Servo amplifier has not
been connected/servo amplifier power OFF" is set in "[Md.26] Axis operation
status" is also varies.
