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 Input (MFI)
is set to 59 (Alt F-Ref UpLimit) and the MFI is on. Alternate Upper Limit Frequency = (B02.04)% x
(E01.04).

B02.01 Frequency Reference
Upper Limit
Sets as a percentage of the maximum
output frequency (E01.04), the
maximum frequency at which the
drive is able to run.

B02.02 Frequency Reference
Lower Limit
Sets as a percentage of the maximum
output frequency (E01.04), the
minimum master frequency reference
only.
0.0–110% 0.0 Basic/Adv
B02.03 Reference 1
Lower limit
Sets as a percentage of the maximum
output frequency (E01.04), and
determines the minimum frequency
the drive is able to run when an analog
signal is below this level.
