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.
