JUMP FREQUENCY WIDTH AND FREQUENCY REFERENCE HOLD FUNCTION SELECTION.



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).
