Number
of
elements
2 integers Number of tracking buffers and their sizes (KB)
<Buffer number>
Specify the number of buffers where the tracking
data is stored.
Mainly the tracking data for each conveyors is
saved at the buffer. Change the set value, when
the conveyor for tracking is increased.
However, if the value is enlarged, the memory
area where the tracking data is saved will be
secured. Be careful because the program number
which can be saved decreases.
Setting range: 1 to 8
<Buffer size>
Specify the size in which the tracking data is
preserved.
Change this element when there is larger tracking
data saved by TrWrt command than reading by
TrRd command.
Be careful because the memory is secured like the
above-mentioned [Buffer number].
Setting range: 1 to 200
8 integers The minimum external encoder data value (pulse)
The range of the encoder value which can be
acquired in state variable "M_Enc"
(minimum value side)
8 integers The maximum external encoder data value (pulse)
The range of the encoder value which can be
acquired in state variable "M_Enc"
(maximum value side)
