Functional Description Set Value and Ramp Adjustment

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 Value Mode Reference frequency
0 or 2 const. ascent 100 / 200 / 400 Hz
Acc. 0 + 1 1 const. time (B) actual set value
forward 3 *const. time (V) last set value at constant run
0 or 8 const. ascent 100 / 200 / 400 Hz
Dec. 2 + 3 4 *const. time (B) actual set value
forward 12 const. time (V) last set value at constant run
0 or 32 const. ascent 100 / 200 / 400 Hz
Acc. 4 + 5 16 const. time (B) actual set value
reverse 48 *const. time (V) last set value at constant run
0 or 128 const. ascent 100 / 200 / 400 Hz
Dec. 6 + 7 64 *const. time (B) actual set value
reverse 192 const. time (V) last set value at constant run
* 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.
