arious function setting and Description
4.3.1 Basic function parameter setting
It is the basic function setting. All settings are factory defaults unless users make
change. It is recommended to use factory setting value unless the parameter
change is necessary.
1) Common parameter setting
The following table shows common parameter setting that should be checked
before use regardless of control mode.
Parameter Name Code Description
Line Freq. FU1-29 Sets a freq of the inverter input power source.
Base Frequency FU1-31 Sets the Motor Base Frequency
1)
.
Motor Rated
Voltage
FU1-50 Sets the Motor Rated Voltage
1)
.
Motor Selection FU2-40
Selects motor and voltage rating suitable to the desired
inverter.
Motor
Parameters
FU2-41
~ 46
Basic parameter value setting when selecting the motor
rating.
Note : If there is any discrepancy between parameter
preset value and the actual motor parameter value, change
the parameter value according to the actual motor.
Drive Mode DRV-3
Operation via Keypad, Fx/Rx-1, Fx/Rx-2 and Int 485
setting.
Frequency Mode DRV-4 Frequency reference source setting parameter
Accel/Decel Time
Setting
DRV-1
DRV-2
Accel/Decel time setting
1) If FU1-31 and FU1-50 are set higher than motor nameplate value, it may cause motor
overheat and if it is set smaller than that, it may cause Over voltage trip during
deceleration. Make sure to enter the actual motor value.
2) V/F control
FU2-60 [Control mode] is set to 0
“V/F” as factory setting. Operation via V/F
control is activated after the above common parameter setting is done and the
followings are set.
Parameter Name Code Description
Starting freq. FU1-32 Set frequency to start the motor.
Torque boost FU2-67 Manual or Auto torque boost settable in this parameter.
Torque boost value
FU2-68
FU2-69 If FU1-67 [torque boost] is set to
“manual”, user sets the
desired value and the direction in code FU1-68 and 69.
3) Slip compensation
Operation is done via Slip compensation if FU2-60 is set to 1 {Slip compen}. This
control keeps motor speed constant regardless of load change.
