AC100 HIGH-PERFORMANCE VC INVERTER MANUAL
FA.04 Fan control
Select fan run mode.
0: Fan run after electrify No matter temperature of module is high or not, fan runs when inverter power on.
1: Fan stop related to temperature Work when running. When inverter stops, fan runs when module temperature is
over 50 degree and stops 30 seconds after module temperature is lower than standard. When inverter runs, fan runs.
2: Fan stop when machine stop, run related to temperature When inverter runs, fan runs when module temperature
is over 50 degree and stops 30seconds after module temperature is lower than standard. When inverter stops, fan
stops.
Note: This function can prolong fan life.
FA.05-FA.06
FA.07
Running OV protection point
Inverter DC bus rated voltage=inverter input rated voltage*1.414
DEC OV protection: Set OV protection point when DEC. Only valid when [FA.01] LED "0" digit is 1.
Running OV protection point: Set OV protection point when ACC or running at constant speed. Only valid when
[FA.01] LED "0" digit is 1.
FA.07 magnetic flow braking gain
Magnetic flow braking is a brake control method of induction motor, valid in induction motor control mode; set [FA.07] to
0 to disable this function. Appropriately increasing [FA.07] can significantly improve the deceleration braking effect;
FA.08 Energy braking act voltage
FA.09
Energy braking action voltage: Inverter energy braking begins when DC bus voltage rises and exceeds (rated voltage
× FA.08). It is only valid for inverter with inner braking parts. Inverters under AC100-T3-018G have build in braking parts.
AC100-S2-3R7G and inverters under than that with 220V input have built-in braking parts. All inverters do not have
braking resistance. If need energy braking, please use optional resistance.
Note: Otherwise overvoltage suppression is possible to suppress the rise of the bus voltage, thus the brake
action point can't be reached.
FA.10
Bus under-voltage protection
This parameter specifies the lower voltage allowed by bus voltage during operation, for some low power occasions,
appropriate under-voltage protection level can be reduced to ensure the normal working of the inverter.
Note: When the grid voltage is too low, the motor output torque will decrease. For constant power load and
constant torque load, low grid voltage will increase the frequency converter input and output current, thereby
reducing the reliability of the inverter operation.
