11. All input signals are ignored during
auto tuning. The variable is automatically
changed to 0 after auto tuning is completed.
Sets the variable to other values to end auto
tuning.
d0.04
Vc_Loop_BW
Sets the bandwidth of the velocity loop in
Hz. The variable can only be set after auto
tuning is performed properly; otherwise the
actual bandwidth goes wrong, which causes
abnormal working of the driver. If the auto
tuning result is abnormal, setting this
parameter may also cause abnormal
working of the driver.
Note: This parameter cannot be applied
when auto tuning is unavailable.

Proper increase in this data will reduce the
tuning error, but machine vibration will
become severer. This data can be adjusted
properly according to actual conditions of
machines. If the data is too small, the auto

Auto tuning is a process where the suitable and stable K_Load value is automatically calculated. In the auto
tuning mode, the data of numeric display is automatically switched to the real-time display mode of K_Load
data. When K_Load data gradually becomes stable, the driver automatically adjusts Kvp and Kvi data of a
velocity loop, so that the actual bandwidth of the velocity loop is 50Hz. When K_Load data becomes stable,
the driver automatically stops auto tuning operation; then you need to customize Vc_Loop_BW, representing
the desired bandwidth of the velocity ring. Finally, run the test system in the actual environment, and save the
parameters.
Precautions:
1. Auto tuning applies when both forward rotation and reverse rotation of a motor are allowable, and the
loadings do not change much during the operation. When forward rotation or reverse rotation of the
motor is not allowable on a device, it is recommended to adjust the parameters manually.
2. During auto tuning operation, pulse signals, digital input signals, and analog signals of the external
controller are temporarily unavailable, so safety must be ensured.
3. Before auto tuning operation, it is recommended to properly adjust the Kvp, Kvi and Speed_Fb_N (a
