(2) Monitor data

"[Md.22] Feedrate"

"[Md.27] Current speed"
 "[Md.28] Axis feedrate"

"[Md.33] Target speed"

"[Md.122] Speed during command"
: For the above monitoring data, "[Pr.83] Speed control 10 x multiplier
setting for degree axis" is evaluated whether it is valid for each axis. If valid,
unit conversion value is changed ( 10
-3
10
-2
). The unit conversion
table of monitor value is shown below.

(3) Speed limit value
 "[Pr.8] Speed limit value"
 "[Pr.31] JOG speed limit value"
 "[Cd.146] Speed limit value at torque control mode"
: For the speed limit value, "[Pr.83] Speed control 10 x multiplier setting for
degree axis" is evaluated whether it is valid for each axis. If valid, the
positioning control will be performed at decuple speed of setting value
(max. speed).
[2] Setting method of "Speed control 10 x multiplier setting for degree
axis function"
Normally, the speed specification range is 0.001 to 2000000.000[degree/min],
but it will be decupled and become 0.01 to 20000000.00[degree/min] by setting
"[Pr.83] Speed control 10 x multiplier setting for degree axis" to valid.
To use the "Speed control 10 x multiplier setting for degree axis function", set the
parameters shown in the following table.
