7.7 Acceleration/deceleration time selection (Ver. 1.30 or later)
Note
• Enable the acceleration/deceleration time setting before starting positioning operation.
→ For the method to enable changed positioning parameters, refer to Subsection 7.1.7
• Do not change the status of the acceleration/deceleration time change command during positioning
operation.
Select the acceleration /deceleration time before starting positioning operation.
If the acceleration/deceleration time selection is changed during positioning operation, the system will
perform the following operation depending on the operation status:
- When the acceleration/deceleration time selection is changed during acceleration/deceleration
The system will operate using the new acceleration/deceleration time. However, attention should be
paid to positioning operation because the acceleration time setting may not be changed with the
intended timing.
- When the acceleration/deceleration time selection is changed during positioning operation at operation
speed
The system will operate using the new deceleration time. If the acceleration/deceleration time selection
is changed just before start of deceleration, the deceleration time setting may not be changed.
If the time needed for the remaining travel distance is shorter than the time needed for deceleration after
a change, the pulse output may decrease suddenly during deceleration.
For 2-speed positioning operation, interrupt 2-speed constant quantity feed, variable speed operation
and multi-speed operation, the system will operate using the new acceleration/deceleration time.
- When the acceleration/deceleration time selection is changed during deceleration
The system will operate using the deceleration time before the change.
However, for 2-speed positioning operation, interrupt 2-speed constant quantity feed, variable speed
operation and multi-speed operation, the system will operate using the changed acceleration/
deceleration time.
