NE200/300 Series Drive User Manual
Chapter 6 Parameter description 177
Note：Only OC, OU has auto reset function.
FC.14 Under-voltage fault treatment Range:0~2【0】
0: No treatment
1: Auto reset after power recovery (reset the UU fault only, do not run
after fault reset.)
2: Auto run after power recovery (Auto run time interval is F1.16)
FC.15 Fast current limit Range:50.0~100.0%【80%】
FC.16 Fast current limit time Range:0.01~1.00s【0.10s】
This function is to protect the drive from tripping by fast current limit in
case of large impact. If the drive is in fast current limit for a long time, the
drive will give fast current limit fault (LC).
The smaller the fast-current-limit value, the smaller loss to the IGBT is.
But too small current limit value will also cause the abnormal working of the
drive. When the fast-current-limit value is set to 100%, there is no fast
current limit function.
FC.17 Overvoltage suppression
mode
Range:0.01~1.00s【0.20s】
When the motor is in generating status, the drive will raise the output
frequency automatically to avoid tripping with over-voltage fault. When this
parameter is set to 0.00Hz, the suppression function is disabled.
6.14 Communication parameters group (Fd)
Fd.00 RS485 communication Range: 0～1【0】
Disable 485 communication function can effectively reduce the
interference, when MODBUS communication is not used.
