 The position memory function is available for coordinate system that remains at the mechanical
origin after the drive’s power-off when using incremental encoder.
For example:
For example, if the motor stops at the absolute position 100000 before power-off, then the
motor’s initial position remains at 100000 and homing has been completed after the drive is
powered on again. With the position memory function, you do not need to do the homing again.
It is time-saving and more efficient.
 The position memory function is valid only when the homing has been completed. Any
incomplete homing cannot work with this function.
 The position memory function only works with motor that has braking mechanism. If you move
the motor by hands or by other methods when the drive is powered off, the saved origin will be
different from the actual origin after power resumes because the drive cannot realize the moving
distance during power-off, further causing a risk of collision when executing position commands.
 When Pr.11-60 bit1 = 0, the single-turn pulse number refers to encoder’s Z-phase signal. But the
communication type encoder does not have Z-phase signal, which makes the setting bit1 = 0
unable to position.
