Memo data
The data is set with the sequence program or peripheral device.
In this chapter, the method using the peripheral device will be explained.
(Refer to "Point" on the next page.)
The basic parameters 1, detailed parameters 1, and OPR parameters become valid
when the PLC READY signal [Y0] turns from OFF to ON.
The basic parameters 2 and detailed parameters 2 become valid immediately when
they are written to the buffer memory, regardless of the state of the PLC READY
signal [Y0].
Even when the PLC READY signal [Y0] is ON, the values or contents of the
following can be changed: basic parameters 2, detailed parameters 2, positioning
data, and block start data.
Set according to the machine and applicable
motor when system is started up.
If the setting of the basic parameters 1 is incorrect, the rotation direction
may be reversed, or no operation may take place.
Set according to the system configuration when
the system is started up.
Set the data for "major positioning control".
Set the data for "high-level positioning control".
)
Set the condition data for "high-level positioning control".
)
Set the condition judgment values for the condition
data used in "high-level positioning control".

MELSEC-Q
Set the data that is determined
by the specification of the servo
being used.
Set the values required for carrying
out OPR control.
