Speed change program
This program is used to change the speed within the " Pr. 5 Speed limit value"

during JOG operation.
Set the new speed in " Cd. 7 New speed value". A speed change is executed
according to " Cd. 6 Speed change request".
The acceleration and deceleration times after speed change are the values set in
" Cd. 8 ACC/DEC time at speed change" and " Cd. 9 DEC/STOP time at speed
change".
(Refer to "Section 11.3 Speed change function" for details of the speed change
