F unction Code Parameter Name Setting Range Default
A5-08 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.
F unction Code Parameter Name Setting Range Default
A5-09 Overvoltage threshold 200.0–2500.0 V 2000.0 V
It is used to set the overvoltage threshold of the AC drive. The default values of different
voltage classes are listed in the following table.
Table 6-12 Overvoltage thresholds for different voltage classes
Voltage Class Default Overvoltage Threshold
Single-phase 220 V 400.0 V
Three-phase 220 V 400.0 V
Three-phase 380 V 810.0 V
Three-phase 480 V 890.0 V
Three-phase 690 V 1300.0 V
Note
The default value is also the upper limit of the AC drive's internal overvoltage protection voltage.
The parameter becomes effective only when the setting of A5-09 is lower than the default value. If
the setting is higher than the default value, use the default value.
