Setting with servo parameters
The rotation/travel direction can be changed without changing the polarity of the command from the controller. With regards to
the commands from the controller, and in the feedback information to be transmitted to the controller, the position/speed
information is changed with the setting of [Pr. PA14 Travel direction selection].
The torque information is changed with the combination of [Pr. PA14 Travel direction selection] and [Pr. PC29.3 Torque POL
reflection selection].
The rotation/travel direction setting is common for all the control modes. For example, when the torque polarity is changed
with [Pr. PA14] and [Pr. PC29.3], the torque information polarity will also change in the position mode.
The servo parameters related to the setting of the rotation/travel direction selection are as follows:
The following tables show the rotation/travel direction of the position information, speed information, and torque information
that is changed in servo parameter settings.

*POL
Travel direction selection
The rotation direction of the servo motor and the travel direction of the linear servo
motor can be set.
Initial value: 0 (CCW or positive direction)

*COPB
Torque POL reflection selection
Torque POL reflection selection can be set.
The torque polarity can be changed with the combination of this servo parameter and
[Pr. PA14].
