NE200/300 Series Drive User Manual
118 Chapter 6 Parameter description
1: Enabled
2: Disabled only at speed-down
AVR means automatic output voltage regulation. When the input voltage
deviates from rated value, AVR function can maintain constant voltage
output. Normally AVR function is recommended to be active. At process of
“deceleration to stop”
F2.18 Over modulation Range: 0~1【1】
0: Enabled
1: Disabled
When the over modulation function is enabled, the drive voltage output
capacity can be improved. However, if the output voltage is too high, the
output current harmonics will increase.
F2.19 Droop control Range: 0.00～10.00Hz【0.00Hz】
When multiple drives drive the same load, the unbalanced load
distribution due to difference speed causes the drive with faster speed to
carry heavier load. The droop control characteristics makes the speed
droop change along with the addition of load, which can lead to balanced
load distribution.
This parameter is used to adjust the frequency change value of the drive
with droop speed.
F2.20 Fan control mode Range: 0～1【0】
0: Auto mode
The fan always runs when the drive is running. After the drive stops
three minutes, the internal temperature detection program will be
activated to stop the fan or keep the fan running according to the
IGBT’s temperature.
