It is used to set the undervoltage threshold of Err09. The undervoltage threshold 100% of the
AC drive of different voltage classes corresponds to different nominal values, as listed in the
following table.
Voltage Class Nominal Value of Undervoltage threshold
Single-phase 220 V 200 V
Three-phase 220 V 200 V
Three-phase 380 V 350 V
Three-phase 480 V 450 V
Three-phase 690 V 650 V
Three-phase 1140 V 1350V
A5-07
SFVC optimization mode selection Default 1
Setting Range
0 No optimization
1 Optimization mode 1
2 Optimization mode 2
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.
A5-08
Dead-zone time adjustment Default 150%
Setting Range 100%–200%
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.
A5-09
Overvoltage threshold Default 2000.0 V
Setting Range 200.0–2500.0 V
