No. Name/Value
23.16 Shape time acc 1
0.000 ...1800.000 s Ramp shape at start of acceleration.
23.17 Shape time acc 2
0.000 ...1800.000 s Ramp shape at end of acceleration.
23.18 Shape time dec 1
0.000 ...1800.000 s Ramp shape at start of deceleration.
Description
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.
