10.3 Asynchronous emulation
(INPUT TYPE = 7)
Through this setting the slip is proportional to the analog voltage.
10.3.1 Analog asynchronous emulation
Through this mode there is the possibility to emulate the behavior of an asynchronous induction motor with a slip and a power
limitation dependent on the load and speed (therefore there could be some differences from each size). The control is expressed
in percentage instead of a defined measure unit. The lower is the slip the higher is the performance and vice versa.
(INPUT TYPE = 8)
Through this setting the fan emulates an ACIM motor and the slip is defined by modifying the Holding Register 66 .
The setting is maintained meanwhile the fan is powered on and it is lost when the fan is powered off.
10.3.2 Modbus temporary asynchronous emulation
(INPUT TYPE = 9)
Through this setting the fan emulates an ACIM motor and the slip is defined by modifying the Holding Register 30 .
The setting is permanent and fan starts at the defined constant slip each time it is powered on.
10.3.3 Modbus fixed asynchronous emulation
The following figures show 6 constant airflow curves randomly chosen and the relationship between the voltage signal and the
corresponding airflow.
