Description of function
The converter di󹪜erentiates two modes for specifying the 󹪝xed speed setpoints:
• Direct mode
• Binary mode
Direct mode
Direct mode is recommended for selecting the 󹪝xed speed setpoints via digital inputs.
In the direct mode, precisely one selection bit c1020 … c1023 is assigned to each 󹪝xed speed
setpoint p1001 ... p1004.
With multiple selection, the converter adds the corresponding 󹪝xed speed setpoints. This
results in an e󹪜ective setpoint with up to 16 di󹪜erent values.
