Note:
The function is used to decide whether need to display alarm when analog signal is
abnormal.
When the setting is 1, warning AE1 and AE2 will display respectively if
analog signal 1 or 2 is abnormal; when the setting is 0, warning will not display.
Pd.14 Auto reset times
Range: 0~10【0】
Pd.15 Reset Interval
Range: 2.0~20.0s every time【5.0s】
Note:
It means there is no auto-reset function when auto reset times is zero. Only three
faults: OC, OU and GF can be auto reset.
Auto reset function can reset these three faults in preset times (Pd.14) and interval
(Pd.15). During the reset interval, the inverter stops output and runs at zero-speed.
It will restart according to start mode after reset. When Pd.14 is set to 0, it means
“auto reset” is disabled and the protective function will be activated in case of fault.
Tips:
Be careful in using auto-reset function, otherwise human injury or material loss may
occur.
SC fault need 10 seconds waiting time for manual reset.
Pd.16 acceleration over-current
counting
Setting range: 0~250【100】
Notes:
In the acceleration process, when the output current reaches the current limiting action
level Pd.05, the inverter’s frequency stops changing, and if continuous current limiting
time reaches the set delay Pd.16, the inverter begins to decelerate. After the current
recovers to the normal value, the inverter continues to accelerate and control current is
not higher than Pd.05.
If OL、OC appears in current limitation during acceleration, the value of Pd.16 should
be reduced appropriately; If the frequency or current oscillate frequently or sharply, the
value of Pd.16 should be increased appropriately; the adjustment of Pd.16 should not
be too large.
