How Incremental Rotary Encoders Work

Incremental rotary encoders use quadrature encoding to track position and direction. This means they generate two signals, A and B, which output square waves shifted by 90°. The phase difference between these quadrature A/B signals lets you detect whether the shaft is rotating clockwise or counterclockwise.

Key Signal Features:

• A/B signals: Two channels with a 90° phase difference for direction detection.
• Index/Z pulse: A single pulse per revolution used as a reference mark for exact positioning.

Pulses per Revolution (PPR) and Counts per Revolution (CPR)

• PPR counts how many pulses the encoder emits in one full shaft turn.
• CPR is the total count including quadrature multiplication:
  • x1 = count each pulse on channel A only
  • x2 = count on both A and B channels
  • x4 = count every rising and falling edge on A and B signals (highest resolution)

Incremental vs. Absolute Encoders

Incremental shaft encoders provide fast, reliable feedback of shaft rotation and direction, with an optional index/Z pulse helping with homing or zero-reference setups. This makes them ideal for applications needing relative movement tracking and speed measurement.

Installation & Mounting Guide

Proper installation is key for your incremental rotary encoder to deliver accurate and reliable feedback. Here are some simple guidelines to ensure smooth setup:

Shaft Coupling Recommendations

• Use flexible couplings to connect the encoder shaft to your motor or equipment shaft; this helps absorb misalignment and reduces wear.
• Avoid using rigid couplings unless shafts are perfectly aligned to prevent damage.
• Check that the shaft diameter matches your incremental shaft encoder (commonly Ø6mm, Ø8mm, or Ø10mm).
• For hollow shaft incremental encoders, secure the shaft properly with the supplied key or set screw.

Wiring Diagrams for A/B/Z Outputs

• The quadrature A/B signals provide direction and speed information, while the index (Z) pulse signals one pulse per revolution for reference.
• Connect the encoder outputs to your controller (PLC, servo drive, or microcontroller) following the specific wiring color codes in the datasheet.
• Choose output type compatible with your system: TTL, HTL, Line Driver (RS-422), or open collector.
• Ensure proper power supply voltage (5VDC, 12V, or 24V depending on model) and observe proper grounding to minimize electrical noise.

Alignment and Calibration Tips

• Align the encoder shaft carefully for smooth rotation without wobble.
• Use the index/Z pulse to establish a home or zero position—this is critical for repeatable positioning in automation and CNC applications.
• After installation, run several revolutions to verify the encoder outputs correctly count pulses and detect direction.
• Calibrate your controller to match the encoder’s Pulses per Revolution (PPR) or Counts per Revolution (CPR).

Following these steps ensures your incremental rotary encoder works perfectly from day one, providing precise relative position, speed feedback, and direction signals for your system.

Frequently Asked Questions (FAQ)

What is the difference between PPR and CPR?

PPR stands for Pulses Per Revolution, which counts the number of pulses generated by the incremental rotary encoder for each full turn of the shaft. CPR, or Counts Per Revolution, refers to the total counts after considering quadrature multiplication (x1, x2, or x4), effectively giving a higher resolution for position tracking.

How do A/B signals detect direction?

Incremental rotary encoders use quadrature A/B signals with a 90° phase difference. By checking which signal leads or lags, the system can determine the rotation direction—forward or reverse.

What happens on power loss?

Since incremental shaft encoders track relative position, they lose their exact position reference on power loss. That’s why the Z pulse (index pulse) is used for homing or reference resetting when the power is restored.

How do I choose the right resolution?

Choosing resolution depends on your application’s precision needs and speed. Higher Pulses Per Revolution (PPR) values offer better accuracy but may require more processing power. For typical speed feedback or motor control, 100 to 1000 PPR works well; precision tasks might need 5000 PPR or more.
