The different ramp functions can be adjusted separately for every frequency change
(acceleration forward, deceleration forward and so on). The selection is made with
oP.10 and is adjustable separately in each set. The function is activated after pressing
„ENTER". In case of several selections the sum of the values must be entered:
Ramp Bit-No
Acc. 0 + 1
forward
Dec. 2 + 3
forward
Acc. 4 + 5
reverse
Dec. 6 + 7
reverse
* Do not adjust these values
If the mode constant time is activated for a ramp, then the s-curve function is
deactivated for this ramp. The ascent is limited to minimum 100 Hz / 300 s.
