6.4 S-shaped ramp generator characteristic
For the ramp generator of the main set-value you can select two
different characteristics under C134:
• linear characteristic for all constant accelerations
• S-shaped characteristic for all jerk-free accelerations.

6.5 Limitation of the frequency setting range
If the drive must rotate in only one direction, because a reversal
may damage material or machine parts, you can restrict the setting
range of the output frequency to one direction of rotation under
C239.
Especially for configurations with closed-loop speed control the drive
may reverse for a short time.
