17.1.118.7 S-shaped ramp
A PT1 element is connected downstream of the linear ramp function generator. This arrangement
implements an S-shaped ramp for a nearly jerk-free acceleration and deceleration.
• The PT1 element can be switched on/off via the bSShapeActive input.
• The corresponding S-ramp time can be set under C00182
.

The ramp function generator runs to 0 within the set
deceleration time.
