P11.4 604 - U/f characteristic curve, mean frequency value 50.00
60.00
0.00 – P11.2 [Hz]
Definition of a frequency value for the voltage value set under
P11.5
Defined ratio (break-point) for the defined U/f-characteristic curve
(P11.1 = 2, see characteristic P11.1 = 2)
P11.5
605 - V/f characteristic curve, mean voltage value 100.00
0.00 - P11.3 %
Definition of a voltage value for the frequency value set under
P11.4
Defined ratio (break-point) for the defined U/f-characteristic curve
(P11.1 = 2, see characteristic P11.1 = 2)
P11.6 606 - Output voltage at 0 Hz 0.00
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.
P11.7 109 - Torque increase 0
0 Deactivated
1 Active
Automatic increase of the output voltage (Boost) with an
increased load and low speed (e.g. heavy starting duty).
h 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.
P11.8 600 - Control mode 0
0 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.
