Chapter 6 A5 control optimization
It is used to set the voltage value of the inverter undervoltage fault Err09. The inverter
with different voltage levels is 100.0%, corresponding to different voltage points:
Single phase / three phase 220V
:
200V
Three phase 380V
:
350V
Three phase 480V
:
450V
Three phase 690V
:
650V

Optimization Mode 1: Used when there is a higher torque control linearity requirement.
Optimization Mode 2: Use when there is a requirement for higher speed stability.

Default
:
150%
Set for 1140V voltage level. Adjusting this value can improve the effective voltage usage. If
the adjustment is too small, the system may be unstable. User modification is not recommended
A5-09
Overvoltage setting
200.0V

2200.0V
Default
:
depend
Used to set the voltage value of the inverter overvoltage fault. The different voltage levels
are respectively:
Default is also the upper limit of the internal overvoltage protection of the inverter. This
parameter setting takes effect only when the A5-09 setting value is less than the respective
voltage level Default. Above Default, the Default is the standard.
