The rounding coefficient is fixed,
t1 = 0.6 set ramp time (linear)
t2 = 0.4 set ramp time (round)
t3 = 1.4 set ramp time
The rounding coefficient is fixed,
t1 = 0.5 set ramp time (linear)
t2 = 1.0 set ramp time (round)
t3 = 1.5 set ramp time
tA1: adjustable from 0 to 100%
tA2: adjustable from 0 to (100% - tA1)
tA3: adjustable from 0 to 100%
tA4: adjustable from 0 to (100% - tA3)
t12 = ACC * (tA1(%) / 100 + tA2(%) / 100 + 1)
t34 = DEC * (tA3(%) / 100 + tA4(%) / 100 + 1)

This parameter is valid for [Acceleration] (ACC), [Deceleration] (dEC), [Acceleration 2] (AC2) and
[Deceleration 2] (dE2).
[0,01]: Ramp up to 99.99 seconds
[0,1]: Ramp up to 999.9 seconds
[1]: Ramp up to 6,000 seconds
ACC

[Acceleration]
0.00 to 6,000 s (2) 3.0 s
Time to accelerate from 0 to the [Rated motor freq.] (FrS) (page 74). To have repeatability in ramps, the value of this
parameter must be set according to the possibility of the application.
dEC

[Deceleration]
0.00 to 6,000 s (2) 3.0 s
Time to decelerate from the [Rated motor freq.] (FrS) (page 74
) to 0. To have repeatability in ramps, the value of this
parameter must be set according to the possibility of the application.
tA1 [Begin Acc round]

g
T
(1)
Rounding of start of acceleration ramp as a % of the [Acceleration] (ACC) or [Acceleration 2] (AC2) ramp time.
Can be set between 0 and 100%.
This parameter can be accessed if the [Ramp type] (rPt) is [Customized] (CUS).
