Installation and Wiring Precautions

Precaution
Use an elastic soft coupling between the encoder shaft and the user output shaft to prevent damage to the encoder shaft system due to misalignment and run-out.
Ensure the allowable axial load is observed during installation.
The axial deviation between the encoder shaft and the user output shaft should not exceed 0.20 mm, and the deviation angle must be no more than 1.5°.
Avoid collisions, impacts, or drops during installation.
Do not reverse the connection of the power line and ground wire.
The ground wire should be as thick as possible, generally recommended to be larger than φ3.
Ensure that encoder output wires do not overlap with each other to avoid damaging the output circuit.
Do not directly connect the signal lines to DC or AC power supplies to prevent damage to the output circuit.
All motors and other equipment connected to the encoder must be properly grounded to prevent static interference.
Use shielded cables for wiring.
Verify that all wiring is correct before starting the equipment.
For long-distance transmission, consider signal attenuation and choose an output mode with low output impedance and strong anti-interference capability.
Avoid using the encoder in strong electromagnetic environments.

Encoder Selection Steps

Step
1. Provide Existing Encoder Information: If you have previously used encoders from other brands, please provide the brand and model information so that our engineers can recommend high cost-performance equivalent replacement products.
2. Determine the Encoder Type: Choose the encoder type based on your application (incremental encoder, absolute encoder, draw-wire sensor, or manual pulse generator).
3. Choose the Output Format/Interface: For incremental encoders, you can select output formats such as NPN, PNP, line driver, push-pull, etc.; alternatively, choose the appropriate interface such as Parallel, SSI, BISS, Modbus, CANopen, Profibus, DeviceNET, Profinet, EtherCAT, Power Link, or Modbus TCP.
4. Choose the Resolution: Gertech incremental encoders can achieve up to 50,000 ppr, while Gertech absolute encoders offer a maximum resolution of 29 bit.
5. Choose the Form Factor: Determine the required enclosure diameter and shaft diameter for your application.
