CHAPTER 4 TYPES AND FUNCTIONS OF SETTING DATA
Setting data refers to data required for positioning control by QD75 and there are eight
types of setting data as shown below. (Block start data is not explained.)
The "Setting data" can be created for each axis and is stored in the QD75 buffer
memory.
Some types of the setting data can be changed only while the PLC READY Y0 is OFF.
Also note that writing the setting data from a peripheral device can only be executed
when the PLC CPU is in the STOP state.

* : For the block start data, refer to the QD75 User's Manual.
(1) The parameter and the OPR parameter are determined by the design of the
positioning hardware.
(2) The positioning data is determined by how the positioning machine is controlled
and operated.
(3) At the time of shipment from the factory, the initial value is set. (The initial value is
same from axis 1 to 4.)
(4) When all the memory addresses are cleared, the initial value is stored.
(5) Setting data change can be performed by the peripheral device or by the TOP or
DTOP instruction of the sequence program.
(Refer to the above chart for information on whether setting data change is
available while the PLC CPU READY Y0 is ON.)
