Frequency Reference 1 (set in b1-01)
Frequency Reference 2
(d1-02 or input terminal A1, A2)
Frequency Reference 3
(d1-03 or input terminal A1, A2)
Frequency Reference 4 (d1-04)
Jog Frequency Reference (d1-17)
<1> The Jog frequency overrides all other frequency references.
d2 Fre uency Upper/Lo er Limits
Upper and lower frequency limits prevent motor speed from going above or below levels that may cause resonance or
equipment damage.
d2 1 Fre uency e erence 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
d2 2 Fre uency e erence Lo er 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.
