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.
No. Parameter Name Setting Range Default
d2-01 Frequency Reference Upper Limit 0.0 to 110.0% 100.0%
n
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.
No. Parameter Name Setting Range Default
d2-02 Frequency Reference Lower Limit 0.0 to 110.0% 0.0%
