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.
No.
d2-02
n d2-03: Master Speed Reference Lower Limit
Unlike frequency reference lower limit (d2-02) which will affect the frequency reference no matter where it is sourced
from (i.e., analog input, preset speed, Jog speed, etc.), the master speed lower limit (d2-03) sets a lower limit that will only
affect the analog input (terminals A1 and A2) that is the active master speed frequency.
