5.1.2 Reference Limits
These parameters will limit the frequency range as a percentage of maximum output frequency (E01.04).
An alternate upper limit frequency can be used during operation when a Multi-Function Digital Input (MFDI) is set to
59 (Alt F-Ref UpLimit) and the MFDI is on. Alternate Upper Limit Frequency = (B02.04) % x (E01.04).
