What Does the ABZ Output Signal of a Magnetic Grating Ruler Mean?

The ABZ output signal of a magnetic grating ruler refers to a common encoding method used in industrial automation to measure position and motion. ABZ represents three channels of output that indicate incremental position pulses (A and B) and an index or zero reference (Z). In industrial equipment, ABZ signals enable accurate position monitoring for precise control and positioning.

In ABZ encoding, A and B are quadrature signals used to determine motion direction. By detecting phase changes between A and B, the system can identify forward or reverse movement. The Z signal is an index pulse used to mark an absolute reference point; after a full rotation, Z generates a pulse indicating the original position.

ABZ signals are widely applied in precision machinery such as CNC machines, laser cutters, and robots. Real-time monitoring of ABZ signals ensures high-precision positioning and motion control, improving production efficiency and product quality.
