PE6000 User Manual Description of Function Codes
171
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.

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
