*1 : Resolution of position “0” will be different according to the resolution of encoder adopted to the product.
But in case of the encoder with 10,000[ppr] resolution, it will be set as 500.
※ When selected resolution is more then encoder resolution, motor shall be operated by microstep between pulses.
