【#3057】 sptc4 Spindle synchronization multi-step acceleration/deceleration changeover
speed 4
Set the speed which switches from 4th step to 5th step in spindle synchronization multi-step
acceleration/deceleration control. Set the same value for the reference axis and synchronous axis.
Set the value of limit rotation speed (slimit) or higher not to carry out a step shift.
---Setting range---
0 to 99999 (r/min)
【#3058】 sptc5 Spindle synchronization multi-step acceleration/deceleration changeover
speed 5
Set the speed which switches from 5th step to 6th step in spindle synchronization multi-step
acceleration/deceleration control. Set the same value for the reference axis and synchronous axis.
Set the value of limit rotation speed (slimit) or higher not to carry out a step shift.
---Setting range---
0 to 99999 (r/min)
【#3059】 sptc6 Spindle synchronization multi-step acceleration/deceleration changeover
speed 6
Set the speed which switches from 6th step to 7th step in spindle synchronization multi-step
acceleration/deceleration control. Set the same value for the reference axis and synchronous axis.
Set the value of limit rotation speed (slimit) or higher not to carry out a step shift.
---Setting range---
0 to 99999 (r/min)
【#3060】 sptc7 Spindle synchronization multi-step acceleration/deceleration changeover
speed 7
Set the speed which switches from 7th step to 8th step in spindle synchronization multi-step
acceleration/deceleration control. Set the same value for the reference axis and synchronous axis.
Set the value of limit rotation speed (slimit) or higher not to carry out a step shift.
---Setting range---
0 to 99999 (r/min)
【#3061】 spdiv1 Time constant magnification for changeover speed 1
Set the acceleration/deceleration time constant to be used at the speed of changeover speed 1
(sptc1) and higher in spindle synchronization multi-step acceleration/deceleration control. Set this as
a magnification in relation to the spindle synchronization acceleration/deceleration time constant
(spt).
---Setting range---
0 to 127
【#3062】 spdiv2 Time constant magnification for changeover speed 2
Set the acceleration/deceleration time constant to be used at the speed of changeover speed 2
(sptc2) and higher in spindle synchronization multi-step acceleration/deceleration control. Set this as
a magnification in relation to the spindle synchronization acceleration/deceleration time constant
(spt).
---Setting range---
0 to 127
【#3063】 spdiv3 Time constant magnification for changeover speed 3
Set the acceleration/deceleration time constant to be used at the speed of changeover speed 3
(sptc3) and higher in spindle synchronization multi-step acceleration/deceleration control. Set this as
a magnification in relation to the spindle synchronization acceleration/deceleration time constant
(spt).
---Setting range---
0 to 127
