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".

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). 

(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".
