guaranteeing uninterrupted running of the Inverter.
However, long-time rapid current limit may cause the Inverter to overheat, which is not
allowed. In this case, the Inverter will report 40=E.CbC, indicating the Inverter is overloaded and
needs to stop.
B5.05
Current detection

0~100
5
☆
It is used to set the Inverter current detection compensation. Too large value may lead to
deterioration of control performance. Do not modify it generally..
B5.06
Undervoltage threshold
60.0%~140.0%
100.0%
☆
It is used to set the undervoltage threshold of 9=E.LU. The undervoltage threshold 100% of the
Inverter of different voltage classes corresponds to different nominal values, as listed in the
following table.

1: Optimization mode 1
It is used when the requirement on torque control linearity is high.
2: Optimization mode 2
It is used for the requirement on speed stability is high.
B5.08
Dead-zone time adjustment
100%~200%
150%
☆
It is only valid for 1140 V voltage class.
You can modify the value of this parameter to improve the voltage utilization rate. Too small
value may system instability. Do not modify it generally.
B5.09
Overvoltage threshold
