FREQUENCY REFERENCE LOWER LIMIT AND JUMP FREQ .






FREQUENCY REFERENCE LOWER LIMIT.

the frequency reference lower limits are set as a percentage of the maximum output frequency (e 1- 0 4), in increments of 1%.

NOTE:
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 (d 2-0 2), the motor will not operate however , if the lower limits is set lower than the minimum output frequency (e 1-0 9). the upper limit and lower limit of output frequency are set as a percentage of the maximum output frequency (e 1-0 4)in increments of 1%

the upper and lower limits of the frequency reference are shown in below fig.



                  upper limit of output frequency(d 2-0 1)







               lower limit of output frequency (d 2-0 2)


                                                                                                                                                                                                set frequency command.



JUMP FREQ.

to set the center values of the frequencies to be jumped in unit of Hz.

NOTE:
to disable this function , set the jump frequency references (d 3-0 1 to d 3-0 3) to 0.0 Hz . be sure to set the jump frequency  so tat d 3-0 3 ~d 3-0 2 ~d 3-0 1. operation is prohibited  with in the jump frequency range  , but changes during acceleration are smooth with no jumps.
jump freq 1,2,3 setting range is 0.0~400.0, and factory setting is 0.00.
