Code
FU2-79 Displays the inverter software version.
FU2-91 [FU2-91], [FU2-92]: Copying parameters from other
FU2-92 inverter
FU2-93 [FU2-93]: Initializing parameters to factory setting values
FU2-94 [FU2-94]: Parameter write disabled
Code
FU1-50
Protection of the motor from overheating without the use of
FU1-51
external thermal relay. Refer to parameter descriptions for
FU1-52
more detail.
FU1-53
FU1-54, FU1-55
Warning alarm outputs and displays the trip message when
FU1-56, FU1-57
overcurrent above the threshold value keeps on.
FU1-58
Set the output current level at which the output freq will be
adjusted to prevent the motor from stoping due to over-
FU1-59, FU1-60
current etc. it activates during accel/ constant speed/ decel
to prevent the motor stall.
Code
5 types of Accel/ Decel pattern: ' Linear' , ' S-curve' , ' U-
FU1-05
curve' , ' Minimum ' , ' Optimum ' settable according to
FU1-06
appplication and load characteristic. If ' S-curve' is selected,
the desired value of [FU2-17], [FU2-18] is settable.
3 types of stopping method ' Decel' , ' DC-brake' , ' Free-run'
FU1-07 selectable. If ' DC-brake' is selected, the desired value of
[FU1-8]~ [FU1-11] is settable.
The motor accelerates after the preset [FU1-12] for the
FU1-12
preset [FU1-13] is applied. Starting DC injection braking is
FU1-13
inactive when the value is set to 0 in control mode other
than V/F and Slip compensation.
Limits the active frequency. Inverter operates at the freq
FU1-23 range between upper freq limit [FU1-25] and bottom freq
FU1-24
limit [FU1-24] and higher/ lower freq value is entered, it is
FU1-25
automatically replaced by limit value. Setting range: [FU1-
20] Maximum freq to [FU1-21] Base freq.
FU2-75 Select the DB resistor mode when the regenerative load. Is
FU2-76 connected. Refer to DBU manual for more details.
