10.7 Acceleration, deceleration, braking, stopping
10.7.1 Setting of acceleration times, deceleration times and S-shaped ramps
The acceleration times and deceleration times determine the controller response
after a setpoint change.
The ramp functiongenerator for the main setpoint canbeset linearly orS-shaped.
The S-shape selection of the main setpoint enables the drive to start and stop
smoothly.
When operating with application I/O three additional deceleration times and
acceleration times can be activated via digital signals.
