3.7.2 Power lines
The three phases of the motor’s power cable have to be connected to
the servo amplifier in such a way that the positive three phase direction
of the motor conforms the positive direction of the linear encoder. This
polarization has to be tested, it cannot be seen at first sight.
Testing the polarization is very important, because a wrong
polarization will result in an uncontrolled run out of the slide.
The power cable can be confectioned by the user to fit on the servo drive.
The power cables are not suited for use in cable chains.
