How to set the CS signal direction by using Pr3.26 “Feedback scale & CS reversal”
There are two types of wiring patterns among CS1, CS2, and CS3 as shown in the figure below. In the figure above,
the wiring among CS1, CS2, and CS3 is correct for the induced voltage, so set the CS signal direction to “not
reversed” using Pr3.26.
On the contrary, in the figure below, the wiring between CS2 and CS3 is the reverse of the figure above, so set the
CS signal direction to “reversed” by using Pr3.26.
The “reversed” CS direction exchanges CS2 and CS3 on the inside of the servo amplifier, so the motor works
properly.
