8.3.2 Adjustment of Brushless DC Electric Motor
No.
Situation that requires
adjustment
How to Adjust
1 Hunching occurs at
positioning stop
Fluctuation in speed
occur during operation 2
Speed is inaccurate
Set the parameter in the following steps, and check the operation.
If an improvement is confirmed in operation, finish the adjustment.
It is not necessary to proceed to the next step.
Procedure 1 : Change Parameter No. 32 “Velocity Loop Integrated Gain”
Set the five types of values below in order, and check the operation.

Go onto Procedure 2 if there is no improvement in operation.
Procedure 2 : Change Parameter No. 31 “Velocity Loop
Proportional Gain” and Parameter No. 32 “Velocity
Loop Integrated Gain”
Set the six types of values below in order, and check the operation.

Contact IAI if there is no improvement in operation.
3 Abnormal noise is
generated / Especially,
when stop or operation in
low speed (less than
20mm/sec), comparatively
high noise is generated.
Change the values for
Parameter No. 31 “Velocity Loop
Proportional Gain” and
Parameter No. 32 “Velocity Loop
Integrated Gain” to the following.
Speed loop proportional gain : 32
Speed loop integral gain : 231
