◆ d2: Frequency Upper/Lower Limits
By entering upper or lower frequency limits, the user can keep motor speed from going above or below levels that may
cause resonance or equipment damage.
■
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.
