(2) Setting the Direction of Coordinate Systems
It is possible to reverse the rotation direction of the motor.
<Setting method>
STEP 1 Select [#parameter] from the main menu of the utility software.
STEP 2 Open the Register parameter tab and then the System Setup Register 1 panel.
STEP 3 Set the rotation direction in Coordinate System Forward Direction Setting from the
System Setup Register 1 panel.

(3) Scaling
Conversion
By using the scaling conversion function, it is possible to freely set the ratio of the amount of
motor movement relative to the instructed amount.
The unit system consists of two types of coordinate systems: command unit coordinate
system and pulse unit coordinate system.
The command unit coordinate system is used for the commands by the built-in controller, and
the pulse unit coordinate system is used for the coordinate system between the drive and the
motor.
The conversion rate of these two unit systems is set in scaling conversion.
Scaling Conversion Formula
