[11] Editing the operation mode of each axis (checkboxes)
One of four operation modes can be set. Select a desired operation mode for each address using the corresponding
checkbox.
Left-click the applicable cell to place an asterisk (*) in the cell.
The occupied I/O size per axis in each mode is as follows:
(1)
Positioner 1 mode ---
4 words each for input and output
(2)
Simple direct mode ---
4 words each for input and output
(3)
Direct numerical specification (positioning) mode --- 8 words each for input and output
(4)
Positioner 2 mode ---
2 words each for input and output
(5)
Solenoid valve mode 1 --- 2 words each for input and output
(6)
Solenoid valve mode 2
2 words each for input and output
Caution
1. If the positioner 1 mode, simple direct mode and direct numerical specification (positioning) mode are combined, set
positioner 1 mode and simple direct mode axes sequentially starting from the youngest axis number, and then specify
direct numerical specification (positioning) mode axes.
Setting cannot be made in the reverse order.
2. Modes in the group that contains the positioner 1 mode, simple direct mode and direct numerical specification
(positioning) mode cannot be combined with modes in the group that contains the positioner 2 mode, solenoid valve
mode 1 and solenoid valve mode 2.
(Example) The positioner 1 mode and solenoid valve mode 1 cannot be combined.
Number of connectable axes
x
Number of axes in positioner 1 mode or simple direct mode = X
Number of axes in direct numerical specification (positioning) mode = Y
Under the above conditions, the numbers of connectable axes X and Y should satisfy the following formula:
X + 2Y d 16 (axes)
The number of I/O words is calculated by the formula below:
4 (X + 2Y) + 8 (words)
x
If the number of axes in the positioner 2 mode, solenoid valve mode 1 or solenoid valve mode 2 is 7:
Z d 16 (axes)
The number of I/O words is calculated by the formula below:
2Z + 8 (words)
