Lenze i550

Example: Using the funcon with a 400-V inverter
With the sengs indicated below, the motor is accelerated aer the start to 50 Hz. As the
base frequency, however, is set very high (here: 599 Hz), the motor voltage at 50 Hz only
amounts to 20 VAC.
Now, the analog input 1 serves to change the motor voltage at constant frequency within a
wide range:

Selecon of an addive voltage setpoint in percent via analog input 1
The seng range (here: 0 ... 100 %) can be adapted via the parameters "Min PID value" and "Max PID value".
Parameter Designaon Seng for this example
0x2636:004 (P430.04) Analog input 1: Min PID value 0 %
0x2636:005 (P430.05) Analog input 1: Max PID value 100 %
0x2860:001 (P201.01) Frequency control: Default setpoint source Frequency preset 1 [11]
0x2911:001 (P450.01) Frequency setpoint presets: Preset 1 50 Hz
0x2B01:002 (P303.02) V/f shape data: Base frequency 599 Hz
0x2B13:001 Addive voltage impression: Enable Funcon Enable [1]
0x2B13:002 Addive voltage impression: Setpoint source Analog input 1 [1]
