7 MEMORY CONFIGURATION AND DATA PROCESS
(1) Transmitting data when power is turned ON or PLC CPU is reset
(
)
When the power is turned ON or the PLC CPU is reset, the "parameters",
"positioning data" and "block start data" stored (backed up) in the flash ROM is
transmitted to the buffer memory.
(2) Transmitting data with TO command from PLC CPU (
The parameters or data is written from the PLC CPU to the buffer memory using
the TO command. At this time, when the "parameter area (b)
data (No. 1 to 600)", "block start data (No. 7000 to 7004)", "control data" and
"PLC CPU memo area" are written into the buffer memory with the TO command,
it is simultaneously valid.
1 Parameter area (b) ...... Parameters validated simultaneously with the writing
POINT
When a value other than "0" has been set to the motor capacity of servo parameter
inside the flash ROM, the power is turned ON or PLC CPU is reset to
Pr.104
transmit the servo parameter inside the flash ROM to the servo amplifier (servo
amplifier LED indicates "b ").
After that, the TO instruction writes the servo parameter from the PLC CPU to the
buffer memory so that the servo parameter in the buffer memory is not transmitted
to the servo amplifier even if the PLC READY signal [Y0] is turned OFF then ON.
Change the servo parameter with the above method, after setting the motor
capacity of servo parameter
to the buffer memory with the TO command.
