7.5.4 FREQUENCY RAMPS
Group of parameters number [106]
Setting the times for ramp-up, ramp-down and the output frequency limits.

[110]
Minimal frequency. 0,00 Hz

frequency
[111]
Using the minimal frequency, it is possible to define the maximal operating speed of the
drive, which is superior to all other ways of entering the speed. For example, defining the
minimal speed of the pump during the pressure regulation, to ensure lubrication and cooling
of bearings and sealings.
Max.
frequency
[111]
Maximal frequency. 50,00 Hz
0,00 Hz ÷
500,00 Hz
Using the maximal frequency, it is possible to define the maximal operating speed of the
drive, which is superior to all other ways of entering the speed.
Ramp type
[107]
Setting the method of entering the frequency ramp parameters. Time adherent
Time adherent
For setting the ramp speed, the ramp-up ( Ramp-up 1 time [116] (page 69), Ramp-up 2 time
[118] (page 69)) and ramp-down ( Ramp-down 1 time [119] (page 70), Ramp-down 2 time
[120] (page 70)) time parameters [s] for single sections will apply.
Slope
adherent
For setting the ramp speed, the ramp-up ( Ramp-up 1 slope [124] (page 69), Ramp-up 2
slope [126] (page 70)) and ramp-down ( Ramp-down 1 slope [127] (page 70), Ramp-down 2
slope [129] (page 70)) slope parameters [Hz/s] for single sections will apply.
RAMP-UP
Group of parameters number [108]
Ramp-up settings. Restriction of motor acceleration.

Ramp-up 1 time
[116]
Ramp-up time for the first section of the frequency ramp. 15,00 s
0,00 s ÷ 3000,00 s First section of the ramp-up is from 0 Hz till the Ramp-up break [117] (page 69) value.
Ramp-up 2 time
[118]
Ramp-up time for the second section of the frequency ramp. 15,00 s
0,00 s ÷ 3000,00 s
Second section of the ramp-up is from the value Ramp-up break [117] (page 69) to the
parameter value Max. frequency [111] (page 69).
Ramp-up break
