JOG FREQUENCY REFERENCE.
the frequency reference when the multi function inputs jog frequency reference selection f jog command and r jog command are on.
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%.
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.
to set the center values of the frequencies to be jumped in unit of Hz.
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.
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 .
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).
