Reference Limits - Magnetek Impulse G+ series 4 Instruction Manual

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.

Function
Sets as a percentage of the
maximum output frequency (E01-
04), which determines the
maximum frequency at which the
drive is able to run.
Sets as a percentage of the
maximum output frequency (E01-
04), which determines the
minimum master frequency
reference only.
Sets as a percentage of the
maximum output frequency (E01-
04), which determines the
minimum frequency at which the
drive is able to run.
Alternate of B02-01 set by
