Chapter 9 Major Positioning Control
(4) When either of three axes exceeds the speed limit, that axis is controlled with
the speed limit value. The speeds of the other axes are limited at the ratios of
"
Da.8
Command speed
".
(Examples)
Axis
Setting item
Axis 1 setting
Axis 2 setting
Axis 3 setting
Pr.8
Speed limit
value
4000.00mm/min
5000.00mm/min 6000.00mm/min
Da.8
Command
speed
8000.00mm/min
6000.00mm/min 4000.00mm/min
With the settings shown above, the operation speed in speed control is as
follows.
Axis 1: 4000.00 mm/min (Speed is limited by
Pr.8
.)
Axis 2: 3000.00 mm/min (Speed is limited at ratios in axes 1, 2, and 3
command speeds.)
Axis 3: 2000.00 mm/min (Speed is limited at ratios in axes 1, 2, and 3
command speeds.)
(Note): Operation runs at speed 1 when a reference axis speed is less than 1
as a result of speed limit.
In addition, when "
Pr.7
Bias speed at start
" is set, the set value will be
the minimum speed.
(5) An error "No command speed (error code: 503)" will occur if a current speed
(-1) is set in "
Da.8
Command speed
".
(6) The software stroke limit check is not carried out when the control unit is set to
"degree".
