Setting the Frequency Reference Function (d2)
The frequency reference function sets the output frequency upper and lower limits.
When the frequency reference is zero and a run command is input, the motor operates at the frequency
reference lower limit (d2-02). The motor will not operate, however, if the lower limit is set lower than the
minimum output frequency (E1-09).

d2-01 Ref Upper Limit 0.0 to

d2-02 Ref Lower Limit 0.0 to

These parameters cannot be changed during operation.
Note The frequency reference upper and lower limits are set as a percentage of the maximum output
frequency (E1-04), in increments of 1%.

Setting Prohibiting Frequency (Jump Frequencies) (d3)
This function allows the prohibition or “jumping” of certain frequencies within the Inverter’s output fre-
quency range so that the motor can operate without resonant vibrations caused by some machine sys-
tems. It is also used for deadband control.

d3-04 Jump Bandwidth 0.0 to
20.0 Hz 1.0 Basic or Advanced
These parameters cannot be changed during operation.
To disable this function, set the jump frequency references (d3-01 to d3-03) to 0.0 Hz.
For d3-01 to d3-03, set the center values of the frequencies to be jumped.
For d3-04, set the jump frequency bandwidth. The jump frequency
±
the jump bandwidth becomes the
jump frequency range.
Operation is prohibited within the jump frequency range, but changes during acceleration and decelera-
tion are smooth with no jumps.
