HVAC Products 7 Application examples 26.02.2003
7.2 Application example 2
A motor shall run at 4 fixed speeds.
− Control is accomplished via digital inputs
− Error message via relay output 1
− Indication of operation via relay output 2
Note: With the settings for this application example, the assumption is made that the parameters use their de-
fault values and that the connected motor has been commissioned with the standard parameters.
If several digital inputs are active at the same time, the setpoint will be added up.
The VSD is started when one of the inputs assumes the ON position.
