(4) If the "new acceleration/deceleration time" is set to "0" and the speed is
changed after the "new acceleration/deceleration time" is validated, the
operation will be controlled with the previous "new acceleration/deceleration
time".
Example
Acceleration/deceleration time

change value during speed
change,enable/disable
Cd.10 New acceleration time value
Cd.11 New deceleration time value
(5) The acceleration/deceleration change function cannot be used during speed
control mode, torque control mode or continuous operation to torque control
mode.
Refer to Section 12.1 "Speed-torque control" for the
acceleration/deceleration processing during speed control mode or
continuous operation to torque control mode.
POINT
If the speed is changed when an acceleration/deceleration change is enabled, the
"new acceleration/deceleration time" will become the acceleration/deceleration time
of the positioning data being executed. The "new acceleration/deceleration time"
remains valid until the changeover to the next positioning data. (The automatic
deceleration processing at the completion of the positioning will also be controlled
by the "new acceleration/deceleration time".)
