*1 If the value ÑForì is adjusted in these parameters (limit values rotation direction
reverse), then the adjusted values for rotation direction forward (oP.6, oP.10
and oP.14) are valid.
In case of setpoint adjustment in percent the minimal and maximal values form the
characteristic for the setpoint calculation (0% = minimal value; 100% = maximal
value). In case of absolute setpoint adjustment the minimal and maximal values
limit the setpoint. Separate limits can be adjusted for both directions of rotation. If
the value ÑForì is adjusted for rotation direction ÑReverseì, then the values for
ÑForwardì are valid.
Setting range:
After the minimal and maximal values the setpoint is limited through the absolute
maximal value and subsequently transferred to the ramp generator. Since the ana-
log setpoint is always calculated onto the maximal values (oP.10, oP.11), it is
possible, to adjust the characteristic of the analog setpoint with the same gain for
both directions of rotations (see Fig. 6.4.5.a) in spite of different maximal output
speeds. If the value ÑForì is adjusted in oP.15, then the absolute maximal speed of
oP.14 is valid for both directions of rotation.
