Startvoltage
Startvoltage
The start voltage is used to apply enough torque to the motors to insure they will run at
low speed.
Attention! In order to prevent over current and unnecessarily high thermal load of the
motor, do not select to high a setting.
Adjustment range: 0 - 25 % (percentage of the maximum output voltage)
Factory setting: 0 %

i.e linear curve pre-programmed.
In the case of linear characteristic curves, the motor achieves full torque
throughout the entire speed range. For fans operation a optimal speed control is
generally achieved through this.
Switching over to square characteristic curve (only permisible in fans and pumps with
square torque moment) might make sense in order to reduce the electromagnetic
motor noises.

Setting for Rampup time and Rampdown time
By separate menus for Rampup time and Rampdown time an adjustment is possible to individual
system conditions.
This function is switched behind the actual controller function.
Rampup time
Rampup time
Time setting in which the automatic controller output from 0 % to 100 % rises.
Setting range: 0...250 sec.
Factory setting: 10 / 20 / 30 / 40 sec. (depending on device type)
Rampdown time
Rampdown time
Time setting in which the automatic controller output from 100 % to 0 % reduces.
Setting range: 0...250 sec.
Factory setting: 10 / 20 / 30 / 40 sec. (depending on device type)
