7 MEMORY CONFIGURATION AND DATA PROCESS
(3) Validate parameters when PLC READY signal [Y0] changes from
OFF to ON
When the PLC READY signal [Y0] changes from OFF to ON, the data stored in
the buffer memory's "parameter area (a) 2" is validated.
2: Parameter area (a) ..... Parameters validated when PLC READY signal [Y0]
changes from OFF to ON.
( Pr.1 to Pr.7 ,
Pr.11
to
Pr.24
,
Pr.43
to
Pr.57
, Pr.200 )
When the motor capacity of servo parameter
Pr.104
inside the flash ROM is set to 0 and a value other
than 0 is set to
Pr.104
in the above step (2), the
servo parameter data is transmitted to the servo
amplifier.
POINT
The setting values of the parameters that correspond to parameter area (b) are
valid when written into the buffer memory with the TO command.
However, the setting values of the parameters that correspond to parameter area
(a) are not validated until the PLC READY signal [Y0] changes from OFF to ON.
(4) Accessing with FROM command from PLC CPU ( )
The data is read from the buffer memory to the PLC CPU using the FROM
command.
(5) Reading the servo parameter from the servo amplifier ( )
When 1 is written to
Cd.102
, the servo parameter is read from the servo amplifier
to the buffer memory.
