- Examples of setting if the limited acceleration curve differs depending on whether
acceleration or deceleration is in progress and whether the movement is in the
minus or plus direction
If the limited acceleration curve differs depending on whether
acceleration or deceleration is in progress or whether the movement is
in the plus or minus direction, the parameters may be set as follows.
The differences from the above example are explained.
(1) For acceleration and movement in the plus direction
If the limited acceleration curve is as shown in the figure below,
set the parameters as follows:
(0.01-% units)
Parameter No. 6714
= 6364 (ratio to the reference acceleration 1750mm/sec
2
at P0)
Parameter No. 6715
= 6364 (ratio to the reference acceleration 1750 mm/sec
2
at P1)
Parameter No. 6719
= 1818 (ratio to the reference acceleration 500 mm/sec
2
at P5)
