5.1.2 Reference Limits
These parameters limit the frequency range as a percentage of maximum output frequency (E01-04). If the lower
limit is below the DC Inj Start Freq (D01-01), then operation will continue according to B03-05.
An alternate upper limit frequency can be used during operation when a Multi-Function Digital Input (MFDI) is set to
59 (Alt F-Ref Up Lmt) and the MFDI is on.
Table 5-3: Reference Limits Parameter Settings
* Initial value is determined by X-Press Programming (
Table 4-6 on page 58
,
Table 4-7 on page 59
or
Table 4-8 on page 60
).

Parameter Display Function Range Default
B02-01 Ref Upper Limit Percentage of the maximum output
frequency (E01-04), which determines the
maximum frequency at which the VFD is
able to run. 0.0–110.0% 100.0*
B02-02 Ref Lower Limit Frequency reference lower limit as a
percentage of maximum output frequency
(E01-04). 0.0–110.0% 0.0
B02-03 Ref1
Lower Limit Frequency reference lower limit, from
analog inputs, as a percentage of
maximum output frequency (E01-04). 0.0–110.0% 2.0*
B02-04 Alt Upper Limit Alternate of B02-01 set by MFDI=59. 0.0–110.0% 0.0
