DA180 series basic AC servo drive
In the expression,

S : Feed corresponding to each rotation motor (mm/rotation)
In this example: g1=50, g2=3
The servo drive has four groups of electronic gear ratio. You can determine which parameters are
selected from P0.25, P0.26, P0.27 P0.28, and P0.29 to make up the electronic gear ratio through
the electronic gear ratio selection terminals SC1 and SC2 of the CN1 plug.

Note:

This group of parameters is valid only when P0.22

If SC1 and SC2 are used for electronic gear ratio switching, P4.10 must be set to 0.

smooth filter time
This parameter specifies the time constant for a first-order low pass filter corresponding to a
position command, reducing the mechanical shock caused by sudden input pulse command
frequency changes.
