P2.24 Frequency Reference 4 Selector
Range: 0 to 9 Default: 0 (None)
These four parameters can be used to configure four individual references that the drive can use for speed control. For information on selecting
between these references see Frequency Reference 1 to 4 Switch (P2.20).
For inputs 0 - 4, the frequency references are transferred directly into the reference system. For inputs 5 - 9, the percentages selected are
converted to Hz using parameters Minimum Frequency Limit (P2.01) and Maximum Frequency Limit (P2.02).
Figure 7-6 Percent to Frequency scaling
If this parameter is set to 0 (None), the drive will run at the Minimum Frequency Limit (P2.01).
The value of these parameters can be set by Frequency Reference Configuration (P2.03).
