Initialization (Precautions)
In the operation of initialization (returning to the home position), if the initialization signal (Z-phase signal from the encoder) is entered
before the motor is not substantially decelerated (after the proximity sensor is activated), the motor may not stop at the required
position. To avoid this, determine the positions with the proximity sensor on and initialization signal on in consideration of the number
of pulses required for successful deceleration. The parameters for setting the acceleration/deceleration time also affect the operation
of initialization, so that these parameters should be determined in consideration of both the positioning and initializing operations.
The motor will start to decelerate with the proximity sensor ON, and stop with the first initialization signal (Z-phase).
The motor will start to decelerate with the proximity sensor ON, and stop with the first initialization Z-phase
signal after the proximity sensor OFF.

If the initial (home) position could not be found within the proximity range, the motor
will repeat deceleration and acceleration while going back and forth (stop with the
proximity sensor (dog) OFF (moving beyond the proximity range) and move in the
opposite direction).
