Basic Parameter 2 - Mitsubishi Electric MELSEC iQ-F Series FX5 User Manual

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
positioning module, Outside speed limit value range (Error code: 1A6AH) occurs. The maximum output pulse rate of the
positioning module is 200 kpulse/s.
■Buffer memory address
The following table shows the buffer memory address of this area.
Buffer memory name
[Pr.8] Speed limit value
■Setting range
The setting range depends on the setting of [Pr.1] Unit setting.
Setting of [Pr.1] Unit setting
0: mm
1: inch
2: degree
3: pulse
*1 When this buffer memory area is set with programs, a calculation is performed in the positioning module 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.
