Speed Limit (Frequency Reference Limit Function)
6-31
Limiting Minimum Frequency
If you do not want the motor to rotate at below a given frequency, use parameters d2-02 or d2-03.
There are two methods of limiting the minimum frequency, as follows:
Adjust the minimum level for all frequencies.
Adjust the minimum level for the master speed frequency (i.e., the lower levels of the jog frequency, multi-
step speed frequency, and auxiliary frequency will not be adjusted).

Adjusting Frequency Lower Limit Using an Analog Input
If you set parameter H3-09 (Multi-function Analog Input Terminal A2 Function Selection) or H3-05 (Multi-
function Analog Input Terminal A3 Function Selection) to 9 (output frequency lower level), you can adjust the
frequency lower level using the terminal A2 input level.

Lower Limit
Determines maximum frequency
reference, set as a percentage of
maximum output frequency
(E1-04). If the frequency
reference is above this value,
actual Drive speed will be limited
to this value. This parameter
applies to all frequency reference
sources.
