B. Working Principle

The Autonics E50S8-500-6-L-5 incremental rotary encoder converts rotation of its shaft into a sequence of electrical pulses.

When the motor, roller, or machine shaft rotates, the encoder shaft rotates with it.

The internal sensing mechanism detects this rotation and generates electrical pulse signals.

The working sequence can be understood as:

Machine shaft rotates → Encoder shaft rotates → Pulse signals are generated → Line driver transmits signals → PLC or controller receives pulses → Speed, direction or position is calculated

500 PPR Resolution

The encoder provides 500 pulses per revolution.

This means that for every complete mechanical revolution, the encoder generates 500 basic pulse cycles.

The connected controller can count these pulses to determine how much the shaft has rotated.

A and B Phase Signals

The encoder provides A and B phase signals.

These two signals are electrically phase shifted from each other.

By comparing the timing of the A and B phases, a compatible controller can determine whether the shaft is rotating clockwise or counterclockwise.

Z Phase Signal

The Z phase provides a reference or index pulse.

It can be used when the control system needs a repeatable reference point during each revolution.

Differential Line Driver Output

The encoder provides complementary signal pairs:

• A and inverse A
• B and inverse B
• Z and inverse Z

The receiving device compares each normal signal with its inverse signal.

This differential transmission method provides reliable pulse communication and helps reduce the effect of electrical noise in industrial environments.
