Current speed (user unit)
This indicates the positioning operation speed.
The user unit is set by unit setting. (Page 385 Unit Setting) The range is 0 to 2147483647 (200 kpps
*1
or lower in pulse).
*1 100 kpps for the FX5S CPU module
The following table lists the corresponding devices.
When the unit system is machine system unit, the current speed can be calculated from the equation below.
• Current speed (machine system unit) = Actual output frequency 60 Pulse No. of per Rotation Movement Amount per
Rotation 10
4
Before being stored in the current speed, the command speed in user unit is converted into pulse unit (pps), and then
converted again into user unit. Thus, because of an error due to this calculation process, a value that is lower than the
command speed may be stored.
In a program with interruption priority 1, the HCMOV/DHCMOV instruction specified with this device for high-speed pulse
input/output module cannot be executed. (Page 115 Interrupt priority)
Max. Speed
Setting method: High Speed I/O Parameter, Special Device
Set the upper limit (maximum speed) for command speed, OPR speed, and creep speed. The user unit is set by unit setting.
(Page 385 Unit Setting)
The setting range is as follows.
Even within the setting range, each of the following relations must be followed: bias speed creep speed OPR speed
maximum speed for the DSZR/DDSZR instruction and bias speed command speed maximum speed for the other
instructions.
