d2: Frequency Upper/Lower Limits
Upper and lower frequency limits prevent motor speed from going above or below levels that may cause resonance or
equipment damage.
n
d2-01: Frequency Reference Upper Limit
Sets the maximum frequency reference as a percentage of the maximum output frequency. This limit applies to all frequency
references.
Even if the frequency reference is set to a higher value, the drive internal frequency reference will not exceed this value.

d2-02: Frequency Reference Lower Limit
Sets the minimum frequency reference as a percentage of the maximum output frequency. This limit applies to all frequency
references.
If a lower reference than this value is entered, the drive will run at the limit set to d2-02. If the drive is started with a lower
reference than d2-02, it will accelerate up to d2-02.
