The ELTRA encoder then subdivides the pulses and chops them to produce higher frequency pulses. Typically, the outputs are A-phase, B-phase, and Z-phase. A-phase and B-phase are pulse outputs that are delayed by 1/4 cycle. The forward and reverse directions can be distinguished based on the delay relationship. Furthermore, the frequency can be multiplied by 2 or 4 by taking the rising and falling edges of A-phase and B-phase. Z-phase is a single-turn pulse, that is, one pulse is emitted per revolution.

Common ELTRA Encoder Faults
1. Encoder Intrinsic Fault: This refers to a fault in the encoder's components,
causing it to fail to generate and output the correct waveform. In this case, the encoder needs to be replaced or its internal components repaired.
2. Encoder Connection Cable Fault: This is the most common fault and frequently encountered during repairs, and should be the first consideration. It is usually caused by an open circuit, short circuit, or poor contact in the encoder cable. In this case, the cable or connector needs to be replaced. Special attention should also be paid to whether the cable is loosely secured, causing a break in the solder joint or an open circuit; in this case, the cable needs to be tightened.
3. Encoder +5V power supply drop: This refers to a +5V power supply that is too low. It should typically not be lower than 4.75V. The cause of this low voltage is a power supply failure or excessive resistance in the power transmission cable, leading to power loss. In this case, the power supply needs to be repaired or the cable replaced.
4. Absolute encoder battery voltage drop: This fault usually has a clear alarm message.
In this case, the battery needs to be replaced. If the reference point position memory is lost, a re-reference point operation must be performed.
5. Encoder cable shield not connected or detached: This introduces interference signals, causing waveform instability and affecting communication accuracy. Reliable soldering and grounding of the shield wire must be ensured.
6. Loose encoder installation: This fault affects position control accuracy, causing excessive position deviation during stopping and movement, and may even trigger a servo system overload alarm immediately upon power-on. Please pay special attention.
7. Grating contamination: This will reduce the signal output amplitude. Oil stains must be gently wiped away with a cotton swab.
Eltra encoders from Italy are devices that encode signals (such as bit streams) or data, converting them into a signal format suitable for communication, transmission, and storage. An encoder converts angular or linear displacement into electrical signals; the former is called a code disk, and the latter a code scale. Encoders can be classified into contact and non-contact types according to their readout method; and into incremental and absolute types according to their working principle. Incremental encoders convert displacement into periodic electrical signals, then convert these signals into counting pulses, using the number of pulses to represent the magnitude of the displacement. Absolute encoders assign a unique digital code to each position; therefore, their reading depends only on the starting and ending positions of the measurement, and is independent of the intermediate steps.
