0.00 - 40.00 %
Definition of a start voltage at 0 Hz (zero frequency voltage)
Note:
A high start voltage enables a high torque at the start.
h
Caution:
A high torque at low speed causes a high thermal
load on the motor. If temperatures are too high, the motor should
be equipped with an external fan.

Active
Automatic increase of the output voltage (Boost) with an
increased load and low speed (e.g. heavy starting duty).

Caution:
A high torque at low speed leads to a high thermal
load on the motor.
Note:
If temperatures are too high, the motor should be fitted
with an external fan.

Frequency control (U/f-characteristic curve)
The setpoint entry controls the output frequency of the frequency
inverter (resolution of the output frequency = 0.01 Hz).
Note
: In this mode, multiple motors, with varying outputs, can be
connected in parallel in the output of the frequency inverter.
1
Speed control with slip compensation,
The setpoint entry controls the motor speed depending on the load
torque (calculation by motor model).
Note
: In this mode, only one motor with the assigned power
(current) may connected in the output of the frequency inverter.
Note: The speed control requires a precise electrical
reproduction of the connected motor
. The ratings plate
information for the motor must be set in the parameter group P7
in this case.
