Setting with object dictionary
[Polarity (Obj. 607Eh)] enables the rotation/travel direction to be changed without changing the polarity of the command from
the controller. The setting of [Polarity (Obj. 607Eh)] for the position information and speed information corresponds to [Pr.
PA14 Travel direction selection]. The setting of [Polarity (Obj. 607Eh)] for the torque information corresponds to [Pr. PA14
Travel direction selection] and "Torque POL reflection selection" in [Pr. PC29].
A change in the setting of [Polarity (Obj. 607Eh)] is not applied immediately.
The table below shows the relations between the object definition, object setting values, and the servo parameters. Settings
can only be made with the combinations indicated here.
