Advanced function setting

SV-iS5 inverter features advanced function parameters to maximize efficiency and performance of the motor. It is
recommended to use as factory setting unless parameter value change is necessary.

Code
FU2-39 Selects Vector_SPD or Vector_TRQ.
Sets the FWD/REV limit to the torque current.
EXT -27, EXT -28
EXT -25, EXT -26 Sets P/I Gain for Vector_SPD control.
EXT -50, EXT -51
Sets speed limit for Vector_TRQ.
EXT -52, EXT -53
Sets on/off of Multi-function output terminal relay when the
EXT -54, EXT -55
motor speed reaches to 0.
EXT -56, EXT -57 Detects certain level/bandwidth of Torque.
Code
Use it according to load characteristics. If User V/F is
selected, user can select the optimum output V/F
FU1-29
characteristic for the application and load characteristics
in [FU1-30]~[FU1-37].
Used to output torque in an intended direction. Inverter
stops acceleration for the preset [FU2-08] Dwell time
FU2-07
while running at Dwell frequency [FU2-07] and starts
FU2-08
acceleration at commanded frequency. Setting [FU2-08]
Dwell time to 0 disable the Dwell operation.
When it is desired to avoid resonance attributable to the
natural frequency of a mechanical system, these
parameters allow resonant frequencies to be jumped. Up
FU2-10
to three areas can be set, with the jump frequencies set to
FU2-11~16
either the top or bottom point of each area. To enable the
function, set [FU2-10] to ' Yes' and set the value in [FU2-
11]~[FU2-16].
This pattern has an effect on the prevention of cargo
FU2-17/ FU2-18 collapse on conveyor etc and reduction in an acceleration/
deceleration shock.
