JOG speed limit value
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.
The use the "
