Timing Chart
In the following timing chart, X-axis positioning with a 4-axis PCU for an
ABSOLUTE MOVEMENT command is stopped by a deceleration stop.
If the STOP Bit is turned ON during memory operation, the Deceleration Stop
Execution Flag for axes for which pulse output is being made will turn ON after
those axes are decelerated to a stop. For example, when memory operation
(started from the X axis) is being performed for the X, Y, and Z axes, if the
STOP Bit for the X axis is turned ON, the Deceleration Stop Execution Flags
for each of the axes will turn ON after all 3 axes have decelerated to a stop.
9-6
Override
The override operation is used for changing the speed of an active axis.
9-6-1
Outline of Operation
While the Override Enable Bit is ON, the target speed is changed by applying
the override value that is set in the operating data area. The override can be
set from 0 to 999%. The speeds set for memory operation, direct operation,
jogging, and so on, are taken to be 100%.
Target speed = Speed setting x Override/100
If the override is greater than the maximum speed for an axis, the target
speed will be the maximum speed.
Override is not enabled for pulse output during origin search. It is enabled,
however, for the pulse output for the amount of compensation when origin
compensation is used.
Normally, override operates immediately. Depending on the function being
used, however, there may be cases where there is a time lag before it oper-
ates, or cases where it does not operate at all.
Note
1.
During override, the acceleration and deceleration times are automatically
adjusted so that the acceleration and deceleration rates are kept constant.
For details on calculating the actual acceleration and deceleration times,
refer to
7-6 Acceleration/Deceleration
and
8-9 Acceleration/Deceleration
.
2.
If the Override Enable Bit is turned OFF, the override value returns to
100%.
