ABB VDF

ABB VARIABLE FREQUENCY DRIVES

F9 EXAMPLE CALCULATIONS AND SETTING THE PARAMETERS

1. Set the VFD parameters for the minimum and maximum SPEEDS of the VFD:

• Set Parameter 1104 REF1 MIN to "20Hz". The motors will never run below this speed.

• Set Parameter 1105 REF1 MAX to "50Hz". The motors will never run above this speed.

2. Next calculate the ACTION LEVEL SIGNAL, the value of the analog signal from the controller

when CO2 = 600ppm:

Therefore:

3. The calculated ACTION LEVEL SIGNAL now needs to be expressed as a percentage of the SIGNAL RANGE,

but since the MINMUM SIGNAL VALUE = 4.0, calculate as follows:

4. Calculate the MAXIMUM RESPONSE LEVEL SIGNAL: the value of the analog signal from the controller

when CO2 = 1000ppm:

Therefore:

5. This calculated MAXIMUM RESPONSE LEVEL SIGNAL now needs to be expressed as a percentage

of the SIGNAL RANGE, but since the MINIMUM SIGNAL VALUE = 4.0, calculate as follows:

6. Set the parameters that will scale the response of the VFD to the inputs from the CO2 controller:

• Set Parameter 1301 MINIMUM AI 1 to "55%" (the MINIMUM SIGNAL VALUE).

• Set Parameter 1302 MAXIMUM AI 1 to "91%" (the MAXIMUM SIGNAL VALUE).
