Description
0: Disable
1: Enable
The function code is used to set the starting bus
voltage of dynamic braking. Adjust this value
properly to achieve effective braking for the
load. The default value varies depending on the
voltage class.
Setting range: 200.0–2000.0V
0: Normal mode
1: The fan keeps running after power-on
2: Run mode 2
0x0000–0x1121
