D2 Reference Limit; D3 Jump Frequencies - YASKAWA VS-616G5 Series Programming Manual

D2 Reference Limits
D2-01 Frequency Reference Upper Limit
Setting Range:
Factory Default:
The frequency reference upper limit is set as a percentage of the maximum output frequency (E1-04)
in increments of 1%.
D2-02 Frequency Reference Lower Limit
Setting Range:
Factory Default:
The frequency reference lower limit is set as a percentage of the maximum output frequency (E1-04)
in increments of 1%. When a run command is input and the frequency reference is less than the lower
limit, operation continues at the frequency reference lower limit. However, when the lower limit is set
to less than the minimum output frequency (E1-09), operation discontinues.
D3 Jump Frequencies
D3-01 Jump Frequency Reference 1
D3-02 Jump Frequency Reference 2
D3-03 Jump Frequency Reference 3
D3-04 Jump Frequency Reference Bandwidth
This function allows the prohibition or "jumping" of critical frequencies so that the motor can operate
without resonant vibrations caused by some machine systems. This function is also used for dead-band
control. Setting the value to 0.0Hz disables this function.
