12 CONTROL SUB FUNCTIONS
[2] Control precautions
If any axis exceeds "
Pr.8
Speed limit value" during 2- to 4-axis speed control,
the axis in excess of the speed limit value is controlled at the speed limit value.
For the other axes which perform interpolation, the speed can be suppressed
by the ratio of a command speed.
If any axis exceeds "
Pr.8
Speed limit value" during 2- to 4-axis linear
interpolation control, 2- to 4-axis fixed-feed control, 2-axis circular interpolation
control, or 3-axis helical interpolation control, the axis exceeding the speed
limit value is controlled at the speed limit value. For the other axes performing
interpolation, the speed can be suppressed by the ratio of a movement
distance.
In 2- to 4-axis linear interpolation control or 2- to 4-axis fixed-feed control, the
speed limit value for the interpolation axis may not function under the following
condition: "1: Reference axis speed" is set in "
Pr.20
Interpolation speed
designation method" or "
Da.29
Interpolation speed designation method", and
the reference axis is the minor axis and the interpolation axis is the major axis.
In 3-axis helical interpolation control, control the composite speed of the
circular interpolation axis or the speed of the linear interpolation axis so that
the speeds do not exceed "
Pr.8
Speed limit value".
[3] Setting method
To use the "speed limit function", set the "speed limit value" in the parameters
shown in the following table, and write them to the QD75.
The set details are validated after they are written to the QD75.

Factory-set
initial value
Pr.8 Speed limit value
Set the speed limit value (max. speed during control).
200000
Pr.31
JOG speed limit
value
Set the speed limit value during JOG operation (max.
speed during control). (Note that " Pr.31 JOG speed
limit value" shall be less than or equal to " Pr.8
Speed limit value".)
20000
Refer to Section 5.2 "List of parameters" for setting details.
REMARK
Parameters are set for each axis.
It is recommended that the parameters be set whenever possible with GX
Configurator-QP. Execution by sequence program uses many sequence programs
and devices. The execution becomes complicated, and the scan times will
increase.
