Ramp-down 1
time [119]
Ramp-down time for the first section of the frequency ramp. 15,00 s
0,00 s ÷ 3000,00
s
First section of the ramp-down is from the value Ramp-down break [121] (page 70) to 0
Hz.
Ramp-down 2
time [120]
Ramp-down time for the second section of the frequency ramp. 15,00 s

Second section of the ramp-down is from the value Max. frequency [111] (page 69) to the
parameter value Ramp-down break [121] (page 70).
Ramp-down
break [121]
Ramp-down break of the frequency ramp.

frequency [111]
If the ramp should be simple (single section), set this parameter to its maximum value.
Ramp-down 1
slope [127]
Setting the ramp-down slope Ramp-down break [121] (page 70) to zero frequency.
5,000
Hz/s
0,001 Hz/s ÷
30000,000 Hz/s
The frequency ramp deceleration in the first ramp-down section.
Ramp-down 2
slope [129] Setting the ramp-down slope from frequency Max. frequency [111] (page 69) to
the frequency Ramp-down break [121] (page 70). 5,000
Hz/s
0,001 Hz/s ÷
30000,000 Hz/s
The frequency ramp deceleration in the second ramp-down section.
Quick reverse
[807]
Setting of the accelerated ramp-down speed against the defined ramp-down, when
the frequency setpoint has the opposite symbol as the frequency ramp output
(Quick reverse command).

The Quick reverse function serves for better drive control on manual control, mainly in
cranes and transport vehicles. For the Quick reverse function it is necessary to dissipate
the kinetic energy through a braking module or flux braking.
S-CURVE
Group of parameters number [872]
Setting the curvature of the frequency profile to the S shape.
Serves for the drive recoil restriction and a smoother operation of the device. It is mainly used for lift, traction
and crane applications.

Name [ID] Description Def.
S-curve
mode [874]
Turning on / off and the selection of the S-curve operation mode.
□ Turning on
the S-curve
Turning on the curvature of the ramp functions. This option is superior to other optional S-
curve modes in individual quadrants of the drive.
□ S -curve
ramp-up +
Turning on / off the S-curve for ramp-up from 0 to positive frequency.
□ S -curve
ramp-down +
Turning on / off the S-curve for ramp-down from positive frequency to 0.
