The following parameter is only available in FC 302:
-
Parameter 14-59 Actual Number of Inverter Units
Perform a power cycle after changing any of the parameters in this parameter group.
Use these parameters when operating the drive under special environmental conditions.
Parameter 14-50 RFI Filter
Table 742: Parameter 14-50 RFI Filter
14-50 RFI Filter
Default value: [1] On
Conversion index: -
Turn the RFI filter on or off. The RFI filter ensures that the drive complies with EMC standards. Select [0] Off only when the drive is
connected to an isolated mains source (IT mains).
Option
[0]

Parameter 14-51 DC-link Compensation
Table 743: Parameter 14-51 DC-link Compensation
14-51 DC-link Compensation
Default value: [1] On
Conversion index: -
The rectified AC-DC voltage in the DC link of the drive is associated with voltage ripples. These ripples can increase in magnitude
with increased load. These ripples are undesirable because they can generate current and torque ripples. A compensation method
is used to reduce these voltage ripples in the DC link. In general, DC-link compensation is recommended for most applications, but
pay attention when operating in field weakening as it can generate speed oscillations at the motor shaft. In field weakening, turn off
DC-link compensation.
