Function 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.
Function Code Parameter Name Setting Range Default
A5-09 2YHUYROWDJHWKUHVKROG 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.

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.
