6.2.2. Direction of Position Scale
You can reverse the sign of the position scale not to observe unpredicted operations when the
Motor mounting direction is reversed.
◊ CW and CCW are the direction when you look the Motor from the Motor output axis
(rotor).
◊ The parameter DI (Direction inversion) specifies counting direction of the position
scale.
◊ The table below shows the relation between the DI data and the counting direction.

When the direction of position scale reading is reversed, the position scale of the following
functions is reversed as well.
◊ All directions of positioning operation
◊ Directions of software travel limits
！
Caution : This manual expresses the rotational direction of the Motor in plus or
minus direction, not by the CW or CCW direction which is seen from
the Motor output axis side. The plus and minus directions depend on
the setting of the parameter DI. So always be careful for the setting of
the DI.
！
Caution : The plus and minus directions of hardware over travel limit and the
phase of position feedback signal output do not reverse even the
position scale direction is reversed.
◊ Input OTP: prevents the CW rotation of the Motor seen from the
Motor output axis.
◊ Input OTM: prevents the CCW rotation of the Motor seen from the
Motor output axis.
When counting the CCW direction as plus
Input the parameter DI to reverse the position scale.
