The default parameter settings (Table 1) on the VFD68 drive are configured to operate a condenser fan motor on an R410 condensing unit, using a P499RCP-107 or P499RAP-107 ratiometric transducer (Figure 1).

For high-pressure refrigerants other than R410a, you must calculate and change the P.90x parameters. For medium and low pressure refrigerants, you must determine the proper P499R transducer and then calculate and change the P.90x parameters.
