d2: Frequency Upper/Lower Limits

By entering upper or lower frequency limits, the drive programmer can prevent operation of the drive above or below levels
that may cause resonance and 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.
d2-01
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 input, the drive will run at the d2-02 level. If the drive is started with a lower reference
than d2-02, it will accelerate up to d2-02.
