2.4 d: Reference Settings
u 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.
d2-01: Frequency Reference Upper Limit
n
Sets the maximum frequency reference as a percentage of the maximum output frequency (E1-04). This limit applies to
all frequency references. The drive internal frequency reference will not exceed this value even when the frequency
reference is set to a higher value.
No.
d2-01 Frequency Reference Upper Limit
d2-02: Frequency Reference Lower Limit
n
Sets the minimum frequency reference as a percentage of the maximum output frequency (E1-04). This limit applies to
all frequency references. Entering a lower reference than this value will cause the drive to run at the limit set in d2-02. If
the drive is started with a lower reference than d2-02, it will accelerate up to d2-02.
No.
d2-02 Frequency Reference Lower Limit
Figure 2.32
d2-03: Master Speed Reference Lower Limit
n
Sets a lower limit that will only affect a frequency reference entered from the analog input terminals (analog input 1 and
analog input 2).
Set as a percentage of the maximum output frequency (E1-04).
Note: When lower limits are set in both parameters d2-02 and d2-03, the drive uses the greater of those two values as the lower limit.
No.
