(3) Cautions
(a) In the following cases acceleration time or deceleration time does not
change when a speed change is executed. The acceleration time or
deceleration time at the time of speed change accept is maintained.
• When setting of the acceleration/deceleration time change enable device
was omitted.
• When setting of new acceleration time value device or new deceleration
time value device was omitted.
• When the device set by new acceleration time value device or new
deceleration time value device is set to "0".

(b) During interpolation control, change of acceleration/deceleration time is
executed by the acceleration/deceleration time change parameter of the axis
No. specified with the speed change command.
(c) Acceleration/deceleration time change function becomes invalid for axes
executing the following servo instructions:
• Circular interpolation control (including point during CPSTART)
• Helical interpolation control (including point during CPSTART)
• Speed control with fixed position stop
(d) Acceleration/deceleration time change function becomes invalid for axes
executing the following acceleration/deceleration methods:
• FIN acceleration/deceleration
• Advanced S-curve acceleration/deceleration control
