RUN Value/Range Description
Factory Setting
(P1.3)
P11.4 604 X — V/Hz characteristic curve, mean frequency value 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 V/Hz-characteristic
curve (P11.1 = 2, see characteristic P11.1 = 2)
P11.5 605 X — V/Hz 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 V/Hz-characteristic
curve (P11.1 = 2, see characteristic P11.1 = 2)
P11.6 606 X — 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
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 X — Torque increase 0
0 Deactivated
1 Enabled
Automatic increase of the output voltage (Boost) with an
increased load and low speed (for example, 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
P11.8 600 X — Control mode 0
0 Frequency control (V/Hz)
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 (vector)
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 motor ratings
plate information must be set in the parameter group P7 in this
case
