JOG FREQUENCY REFERENCE.

the frequency reference when the multi function inputs jog frequency reference selection f jog command and r jog command are on.

NOTE:
the frequency reference default value and set value will change when 0 1-0 3 is changed, for example if preset reference 1 is set to 6.00 Hz and 01-03 is changed to 1 (0.01%units ,the setting for preset reference 1 will become 10.00%. when using preset reference 2 through 8 be sure to set multi step speed reference 1, 2 and 3 in the multi function inputs (h 1-0 1 through h 1-0 6 ) as required. when using the jog function set the jog frequency reference in constant d 1-0 9 when jogging from an external terminal set the multi function inputs (h 1-0 1 through h 1-0 6)to jog frequency reference forward jog or reverse jog as required . the multi function input setting is unnecessary when jogging from the operator.

FREQUENCY REFERENCE UPPER LIMIT.
the frequency reference upper is set as a percentage f the maximum output frequency (e 1- 0 4) in increments of 1%.
setting range is 0.00~110.0 .
factory setting is 100
change during operation is x.
v/f is b .
f/f with pg is b.
open loop vector is b ,
flux vector is b .

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.

JUMP FREQUENCY WIDTH.

to set the range of the frequency to be jumped in unit of Hz .the jump frequency +- the jump frequency band width becomes the jump frequency range.

NOTE:
to jump the mechanical resonance frequency which is with in the output frequency range of inverter. to set the dead band of frequency , to set prohibited frequency (d 3-0 1~0 3) to 0.0 Hz . the frequency jump function will not work . be sure to set the center value of prohibited frequency and make sure that  d 3- 0 3 <d 3-0 2<d 3-0 1. d 3-0 4, set the jump frequency band width , the jump frequency+- the jump frequency range . operation is prohibited with in the jump frequency range but changes during acceleration and deceleration are smooth with no jumps . the relation between the internal frequency reference.

FREQUENCY REFERENCE HOLD FUNCTION SELECTION.

to set whether he holds status frequency command needs to be retained or not , 0:disable restart after operation stoppage or power up begins at zero, 1:enabled, restart after operation stoppage or power up begins at the held frequency reference .

NOTE:
constant d 4-0 1 is enabled by making either of the following setting for the multi function inputs (h 1-0 1 to h 1-0 6). acceleration/deceleration ramp hold (setting ,a, up command (setting ,10)/down command (setting , 11)when hold status is established by these external signals, specify whether or not the output frequency is to be retained , when this function is enabled operation is restarted after power up using the frequency reference value that was retained, for information regarding the acceleration/deceleration stop (hold) command and the up/down command , after to the description of multi function inputs (h 1).
