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. Note, however, that the
only valid value of the "
the PLC READY signal [Y0] turns from OFF to ON for the first time after the power
is switched ON or the CPU module is reset. Once the PLC READY signal [Y0] has
been turned ON, the value will not be reset even if another value is set to the
parameter and the PLC READY signal [Y0] is turned from OFF to ON.
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 block start 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".
