0 ASR control at sensorless torque
0:use PI as ASR; 1:use P as ASR
1~10 NA
11 Activate DC braking when executing zero torque command
0:ON , 1:OFF
12 FOC Sensorless mode, cross zero means speed goes from negative to
positive or positive to negative (forward to reverse direction or reverse to
forward direction). 0: determine by stator frequency , 1: determine by speed
command
13 NA
14 NA
15 Direction control at open loop status
0: Switch ON direction control 1: Switch OFF direction control
Except Bit=0 set to be used in closed loop, other Bit settings are for open loop.
FOC Bandwidth of Speed Observer
Settings 20.0~100.0Hz
Setting speed observer to higher bandwidth could shorten the speed response time but will create
greater noise interference during the speed observation. .
FOC Minimum Stator Frequency
Settings 0.0~10.0%fN
This parameter is used to set the minimum level of stator frequency at operation status. This
setting ensures the stability and accuracy of observer and avoid interferences from voltage,
current and motor parameter. fN is motor rated frequency.
FOC Low-pass Filter Time Constant
Settings 1~1000ms
This parameter sets the low-pass filter time constant of a flux observer at start up. If the motor can
not be activated during the high-speed operation, please lower the setting in this parameter.
