Inovance MD300 - Group F4 Input Terminal

Parameter Description MD320/MD320N User Manual
110
It is enabled only for V/F control. Setting this parameter can compensate the slip in the V/F
control mode due to load and reduce the change of rotation speed of the motor following the
load change. In general, 100% corresponds to the rated slip of the motor with rated load. Slip
coefcient adjustment can refer to the following principles: When the load is rated load and the
slip compensation coefcient is set to 100%, the rotation speed of the motor in the inverter is
close to the given speed.

AVR(Automatic Voltage
Regulation)
Factory default value 2
Setup range
0 Inactive
1 Enabled
2 Inactive only at the time of deceleration
In the V/F control mode, when it needs fast stop and there is no brake resistor, selecting “Inactive
only at the time of deceleration” can greatly reduce the possibility of over voltage fault alarm.
When there is brake resistor or it has not need for fast deceleration, select “Active”.
F3-11
Oscillation suppression gain Factory default value
Setup range 0 ~100
Select “0” for this gain when the motor has no oscillation. Only when the motor has obvious
oscillation and cannot run normally can this gain be properly increased. The bigger the gain is,
the better oscillation suppression result will be. The method of selecting this gain is to select
the smallest one on the premise that there is effective oscillation suppression measure, so as
to ease the negative effect on the VF operation.
Group F4 Input Terminal
The standard unit of MD320 series inverter has ve multifunctional digital input terminals (DI5
of which can be used as high-speed pulse input terminal) and two analog input terminals. If the
system needs more input/output terminals, optional multifunctional input/output expansion card
can be used.
The multifunctional input/output expansion card has 5 multifunctional digital input terminals (DI6
to DI10) and 1 analog input terminal (AI3).
