Basic parameter 2
This section describes the details on the basic parameter 2.
[Pr.8] Speed limit value
Set the maximum speed during positioning control and OPR control. If the specified speed exceeds the speed limit value,
positioning is limited at the speed limit value.
Positioning control speed must be limited properly depending on the device and control subject.
When the command pulse frequency (pulse/s) converted from the speed limit value exceeds the maximum output pulse of the
RD75, Outside speed limit value range (Error code: 1A6AH) occurs. The maximum output pulse of the RD75 is 200kpulse/s
for the RD75P
 and 5Mpulse/s for the RD75D  .
■
Buffer memory address
The following table shows the buffer memory address of this area.
■
Setting range
The setting range depends on the setting of [Pr.1] Unit setting.
*1 When this buffer memory area is set with programs, a calculation is performed in the RD75 to convert a setting value to the value in
each unit. For setting this buffer memory area, take the value after the unit conversion into consideration.
■
Default value
The default value is 200000 for all the axes.
