(2) Phase initialization
If the servo drive is used with incremental encoder, when its power is turned on for the first time, the
procedure of finding electrical angle or phase initialization must be done. For HIWIN linear servo
motor, electrical angle can be successfully found without moving the motor for a long distance.
Another commonly-used method for phase initialization is by using Hall sensor. Normally phase
initialization and enabling can be completed via an output signal from controller (such as I1 input of
D1 servo drive).
