Parameters 175
22.06 Shape time acc1 Defines the shape of the acceleration ramp at the beginning
of the acceleration.
0.000 s: Linear ramp. Suitable for steady acceleration or
deceleration and for slow ramps.
0.001…1000.000 s: S-curve ramp. S-curve ramps are ideal
for lifting applications. The S-curve consists of symmetrical
curves at both ends of the ramp and a linear part in between.
Acceleration:
Deceleration:
0.000 … 1800.000
s
Ramp shape at start of acceleration. 1000 = 1 s
22.07 Shape time acc2 Defines the shape of the acceleration ramp at the end of the
acceleration. See parameter 22.06 Shape time acc1.
0.000 … 1800.000
s
Ramp shape at end of acceleration. 1000 = 1 s
22.08 Shape time dec1 Defines the shape of the deceleration ramp at the beginning
of the deceleration. See parameter 22.06 Shape time acc1.
0.000 … 1800.000
s
Ramp shape at start of deceleration. 1000 = 1 s
