Explanation
- Display of the servo axes

Servo axis load meters as many as the maximum number of controlled
axes of the path can be displayed. One screen displays load meters for
up to five axes at a time. By pressing the soft key [MONITOR], load
meters for the 6th axis and up are displayed.

- Display of the spindle axes

When serial spindles are used, the reading on the load meter and
speedometer can be displayed only for the main serial spindle.

- Unit of graph

The bar graph for the load meter shows load up to 200% (only a value
is displayed for load exceeding 200%).
The bar graph for the speedometer shows the ratio of the current
spindle speed to the maximum spindle speed (100%).

- Load meter

The reading on the load meter depends on servo parameter No. 2086
and spindle parameter No. 4127.

- Speedometer

Although the speedometer normally indicates the speed of the spindle
motor, it can also be used to indicate the speed of the spindle by setting
bit 6 (OPS) of parameter No. 3111 to 1.
The spindle speed to be displayed during operation monitoring is
calculated from the speed of the spindle motor (see the formula below).
The spindle speed can therefore be displayed, during operation
monitoring, even when no position coder is used.
To display the correct spindle speed, however, the maximum spindle
speed for each gear (spindle speed at each gear ratio when the spindle
motor rotates at the maximum speed) must be set in parameters No.
3741 to No.3744.
The input of the clutch and gear signals for the first serial spindle is
used to determine the gear which is currently selected. Control the
input of the CTH1A and CTH2A signals according to the gear
selection, by referring to the table below.
(Formula for calculating the spindle speed to be displayed)

operation monitoring, only for the first serial spindle and the spindle
switching axis for the first serial spindle. It cannot be displayed for the
second spindle.

- Color of graph

If the value of a load meter exceeds 100%, the bar graph turns purple.

Explanation
- Tool tip position

The addresses of the three basic machine configuration axes for
performing three-dimensional manual feed and the current position of
the tool tip are displayed.

- Tool axis reference (number of pulses)

The amount of travel in the tool axis direction in tool axis
direction handle feed, tool axis direction jog feed, or tool axis
direction incremental feed is displayed.
The unit is the least input increment of the axis in the direction
specified by parameter No. 19697.

The amount of travel in the first axis direction in tool axis
right-angle direction handle feed, tool axis right-angle direction
jog feed, or tool axis right-angle direction incremental feed is
displayed.

The unit is the least input increment of the axis in the first axis
direction normal to the direction specified by parameter No.
19697.

The amount of travel in the second axis direction in tool axis
right-angle direction handle feed, tool axis right-angle direction
jog feed, or tool axis normal direction incremental feed is
displayed.

The unit is the least input increment of the axis in the second axis
direction normal to the direction specified by parameter No.
19697.

- Tool tip center (number of pulses)

The angular displacement in tool tip center rotation handle feed,
tool tip center rotation jog feed, or tool tip center rotation
incremental feed for rotation of the first rotary axis is displayed.
The unit is the least input increment of the first rotary axis.

The angular displacement in tool tip center rotation handle feed,
tool tip center rotation jog feed, or tool tip center rotation
incremental feed for rotation of the second rotary axis is
displayed. The unit is the least input increment of the second
rotary axis.

table reference vertical direction handle feed, table reference
vertical direction jog feed, or table reference vertical direction
incremental feed is displayed.

The unit is the least input increment of the axis in the direction
specified by parameter No. 19697.

The amount of travel in the first axis direction in table reference
horizontal direction handle feed, table reference horizontal
direction jog feed, or table reference horizontal direction

- Amounts of machine axis travel

The addresses of machine configuration axes used for
three-dimensional manual feed and the sum of the amount of travel of
each axis used for three-dimensional manual feed are displayed.
The values of the basic three axes (X-axis, Y-axis, and Z-axis), the
first rotary axis, and the second rotary axis are displayed in this order.
For the definition of the first rotary axis and second rotary axis, see
