7 MEMORY CONFIGURATION AND DATA PROCESS
(10) Transmitting servo parameter from the buffer memory area to
servo amplifier ( )
The servo parameter in the buffer memory area is transmitted to the servo
amplifier by the following timing.
1) The servo parameter transmitted to the servo amplifier when communications
with servo amplifier start.
The servo parameter in the buffer memory area is transmitted to the servo
amplifier.
2) The following servo parameter in the buffer memory area carried out to the
servo amplifier when the PLC READY signal [Y0] turns from OFF to ON.

About the communication start with servo amplifier
Communication with servo amplifier is valid when following condition is realized
together.
1) The power of QD75MH and servo amplifier is turned ON.
2) When the servo parameter "
Pr.100
Servo series" inside the buffer memory
area is set to the value other than "0" in QD75MH.
When the power is turned ON or the PLC CPU is reset, the data stored in the
flash ROM is transmitted to the buffer memory.
Therefore the servo parameter "
Pr.100
Servo series" inside the flash ROM is
stored to the value other than "0", and communication with servo amplifier is
started when the power is turn ON in order of the servo amplifier, QD75MH.
After the servo parameter stored in the flash ROM is transmitted to the servo
amplifier.
How to transfer the servo parameter setup from PLC program to the
servo amplifier
The servo series of servo parameter "
Pr.100
Servo series" inside the flash ROM
set to "0".
(Initial value: "0")
The setting values of the parameters that correspond to the servo parameter
"
Pr.100
Servo series" inside the flash ROM are not started when the power is
turned ON or the PLC CPU is reset, after the communication with servo amplifier
is not started.
