Parameters 159
23.16 Shape time acc 1 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.
Note: For safety reasons, shape times are not applied to
emergency stop ramps.
