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, 3 and 4
Axis 3: 2000.00 mm/min (Speed is limited at ratios in axes 1, 2, 3 and 4
Axis 4: 750.00 mm/min (Speed is limited at ratios in axes 1, 2, 3 and 4
Note: Operation runs at speed 1 when a reference axis speed is less than 1 as
a result of speed limit.
In addition, when a bias speed is set, it 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".
