6-5-4 Reference Parameters (d)

H 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).
Parameter Display name p y
number
d2-01 Ref Upper Limit
d2-02 Ref Lower Limit
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%.
Frequency reference upper limit (d2-01)
Frequency reference lower limit (d2-02)
H 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.
Parameter Display name p y
number
d3-01 Jump Freq 1
d3-02 Jump Freq 2
d3-03 Jump Freq 3
d3-04 Jump Bandwidth
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
jump frequency range.
Operation is prohibited within the jump frequency range, but changes during acceleration and decelera-
tion are smooth with no jumps.
