(P1.3)<br />
P11.4 604 X — V/Hz characteristic curve, mean frequency value 60.00<br />
0.00–P11.2 (Hz) Definition of a frequency value for the voltage value set under<br />
P11.5<br />
Defined ratio (break-point) for the defined V/Hz-characteristic<br />
curve (P11.1 = 2, see characteristic P11.1 = 2)<br />
P11.5 605 X — V/Hz characteristic curve, mean voltage value 100.00<br />
0.00–P11.3 Definition of a voltage value for the frequency value set under<br />
P11.4<br />
Defined ratio (break-point) for the defined V/Hz-characteristic<br />
curve (P11.1 = 2, see characteristic P11.1 = 2)<br />
P11.6 606 X — Output voltage at 0 Hz 0.00<br />
0.00–40.00% Definition of a start voltage at 0 Hz (zero frequency voltage)<br />
Note: A high start voltage enables a high torque at the start<br />
Caution: A high torque at low speed causes a high thermal<br />
load on the motor. If temperatures are too high, the motor<br />
should be equipped with an external fan<br />
P11.7 109 X — Torque increase 0<br />
0 Deactivated<br />
1 Enabled<br />
Automatic increase of the output voltage (Boost) with an<br />
increased load and low speed (for example, heavy starting duty)<br />
Caution: A high torque at low speed leads to a high thermal<br />
load on the motor<br />
Note: If temperatures are too high, the motor should be fitted<br />
with an external fan<br />
P11.8 600 X 0 Control mode<br />
<strong>Frequency</strong> control (V/Hz)<br />
The setpoint entry controls the output frequency of the<br />
frequency inverter (resolution of the output frequency =<br />
0.01 Hz)<br />
Note: In this mode, multiple motors, with varying outputs, can<br />
be connected in parallel in the output of the frequency inverter<br />
0<br />
1 Speed control with slip compensation (vector)<br />
The setpoint entry controls the motor speed depending on the<br />
load torque (calculation by motor model)<br />
Note: In this mode, only one motor with the assigned power<br />
(current) may connected in the output of the frequency inverter<br />
Note: The speed control requires a precise electrical<br />
reproduction of the connected motor. The motor ratings<br />
plate information must be set in the parameter group P7 in this<br />
case<br />
