d2-01: Frequency Reference Upper Limit
No.
Name
(Hex.)
d2-01 Frequency Reference
Upper Limit
(0289)
The drive operates at the value set in d2-01 even if the frequency reference exceeds the value set in d2-01.
■
d2-02: Frequency Reference Lower Limit
No.
Name
(Hex.)
d2-02 Frequency Reference
Lower Limit
(028A)
The drive operates at the value set in d2-02 even if the frequency reference falls below the value set in d2-02. The
motor will accelerate up to d2-02 after the Run command is switched ON and a lower frequency reference than
d2-02 has been entered.
■
d2-03: Analog Speed Reference Low Limit
No.
Name
(Hex.)
d2-03 Analog Speed
Reference Low Limit Sets the lower limit of the master frequency reference (Multi-Step Speed 1)
(0293)
The lower limit of Jog reference, frequency reference for multi-step speed operation and the auxiliary frequency
reference will not be adjusted.
The drive operates at the value set in d2-03 even if the frequency reference falls below the value set in d2-03.
Note:
When lower limits are set to both parameters d2-02 [Frequency Reference Lower Limit] and d2-03, the drive uses the greater of those
two values as the lower limit.

d3: Jump Frequency

The Jump frequency is a function that sets the dead band to a certain frequency band. Performing variable speed
operation of the machine that was running at a constant speed may make resonance. To run the machine avoiding
resonance due to the natural frequency of the machinery mechanical system, perform a specific frequency band
jump.
The drive can be programmed with three separate Jump frequencies. Sets d3-01 to d3-03 [Jump Frequencies] to
the median value for the jumped frequency and set d3-04 [Jump Frequency Width] to the Jump frequency width.
If a frequency reference was input that is the same as or close to the Jump frequency width, the frequency
reference changes automatically.
The drive accelerates or decelerates the motor smoothly until the frequency reference falls outside the range of the
Jump frequency band. The drive will use the active accel/decel time to pass through the specified dead band
range. If the frequency reference falls outside the range of the Jump frequency band, switch to constant speed
operation.
