1 SERVO PARAMETER DETAILS
1.2 Basic setting servo parameters group ([Pr. PA_ _ ])
[Pr. PA14_Travel direction selection (*POL)]
The rotation/travel direction can be changed without changing the polarity of the command from the controller.
The polarities of the position and speed information are changed by the setting value of [Pr. PA14 Travel direction selection].
Torque information changes with the combination of [Pr. PA14] and [Pr. PC29.3 Torque POL reflection selection].
The rotation/travel direction is enabled regardless of 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 and positioning mode.
