Description
Control Mode Selection
FU2-39
Selects Vector_SPD or Vector_TRQ.
Forward/ Reverse
Torque Limit
EXT -27, EXT -28
Sets the FWD/REV limit to the torque current.
P-Gain/ I-Gain for
(Sensored) Vector_SPD
EXT -25, EXT -26 Sets P/I Gain for Vector_SPD control.
Speed Limit setting
EXT -50, EXT -51
EXT -52, EXT -53
Sets speed limit for Vector_TRQ.
Zero Speed Detection
Level/ Bandwidth
EXT -54, EXT -55
Sets on/off of Multi-function output terminal relay when the
motor speed reaches to 0.
Torque Detection
Level/Bandwidth
EXT -56, EXT -57 Detects certain level/bandwidth of Torque.
3.1.2
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.
1) V/F control
Parameter Name
Code
Description
V/F Pattern
FU1-29
Use it according to load characteristics. If User V/F is
selected, user can select the optimum output V/F
characteristic for the application and load characteristics
in [FU1-30]~[FU1-37].
Dwell operation
FU2-07
FU2-08
Used to output torque in an intended direction. Inverter
stops acceleration for the preset [FU2-08] Dwell time
while running at Dwell frequency [FU2-07] and starts
acceleration at commanded frequency. Setting [FU2-08]
Dwell time to 0 disable the Dwell operation.
Frequency jump
FU2-10
FU2-11~16
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
to three areas can be set, with the jump frequencies set to
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].
S-curve Accel/Decel
pattern
FU2-17/ FU2-18
This pattern has an effect on the prevention of cargo
collapse on conveyor etc and reduction in an acceleration/
deceleration shock.
