• Speed accuracy is
insufficient
Set the parameters following the procedure below and check the
operation.
When the motion improves, end the adjustment. There is
no need to proceed to the next step.
Step 1: Change Parameter No. 32 "Velocity Loop Integral Gain",
set the following 5 values in order and check the operation.
If the operation does not improve, perform step 2.

or at low speed (20 mm/s
or less
)
Change Parameter No. 31 "Velocity Loop Proportional
Gain" and Parameter No. 32 "Velocity Loop Integral Gain"
to the following values and confirm.
Velocity Loop Proportional Gain: 32
Velocity Loop Integral Gain: 231
