T1 stands for F5-07, during which the output frequency change slope (that is, speed change
rate) increases gradually. T2 is stands for F5-08, during which the output frequency change
slope reduces gradually to low speed frequency. Between T1 and T2, the output frequency
change slope keeps unchanged.
Function Code Parameter Name Setting Range Default Min. Unit
F5-16 Speed deviation threshold 0%–80% 50% 0%
F5-17
Time for determining speed
deviation too large
0–5000 ms 400 ms 1 ms
The speed deviation detection function of the NICE900 is effective only in the CLVC mode.
The controller determines whether the deviation between the running frequency and the
frequency reference is too large based on the value of F5-16. If the deviation remains too large
for more than the time set in F5-17, the controller reports Er32 and performs protection for too
large speed deviation.
When F5-16 is set to 0, the controller does not detect speed deviation.
Function Code Parameter Name Setting Range Default Min. Unit
F5-18 Door close steady speed delay 0–9999 ms 200 ms 1 ms
It is used to set the steady speed delay at door close. The controller determines whether door
close is hindered only after the steady speed delay in F5-18.
Function Code Parameter Name Setting Range Default Min. Unit
F5-19 Fault braking current 0.1%–150.0% 100% 0.1%
After detecting overspeed, reversal or encoder signal abnormality, the controller performs
braking with the current set in this parameter and reports the fault after completion of braking.
If this parameter is set to 0, this function is invalid.
Group F6: Distance Control Parameters
Function Code Parameter Name Setting Range Default Min. Unit
F6-00 Door width auto-tuning function 0, 1 0 1
It is used to enabled or disable the door width auto-tuning function.
