You can use the default parameter setting with the P499RxP-107C transducer and R410a refrigerant within a range of operation that depends on the specific model of P499 transducer selected. All other applications require some parameter changes and may require different transducers.

| P. 32 | Frequency Jump 1B: Maximum frequency to skip over to avoid very low fan
airflow and unnecessary motor overheating. (9999: frequency jump not
enabled)1
Note: Ensure that this is set equal to P.902 (screen

1 If P. 32 = 9999, then the speed
of the motor controlled by the VFD68 will not drop below P. 2
(minimum motor speed), regardless of the mode selected.
2 If the VFD68 supply voltage is
greater than the motor rating voltage (such as when using a 208 VAC
motor with a 230 VAC supply), enter the motor rating voltage for P.
19. This allows the motor to run cooler.
3 A setting value of 0 indicates
0.7 kHz. A setting value of 1 indicates 1 kHz. A setting value of 15
indicates 15 kHz.
