There are two ways to exit:
A Power off.
B Reset command (FF).
Z-axis Input Function : The Z0-Z7 limit value is ±7
Z-axis counter accumulates the Z1, Z2 phase changed by movement. This mode
includes noise immunity.
Z/2 : 2 dot per count. The wheel should stay at Z1=0, Z2=0 or Z1=1, Z2=1 Phase
Z/4 : 4 dots per count. the wheel should stay at Z1=0, Z2=0 phase.
