GSA-S Series Single-Turn SSI Absolute Rotary Encoder
GSA-S Series Single-Turn SSI Absolute Rotary Encoder3
Synchronous Serial Interface (SSI) is point-to-point so slaves cannot be bussed together. SSI is uni-directional, data transmission being only from slave to master. It is therefore not possible for a master to send configuration data to a slave. Communication speeds are limited to 2 Mbits/sec.Many SSI devices implement double transmissions to improve communication integrity. The master compares the transmissions to detect errors. Parity checking (Appendix) further improves error detection.SSI is a relatively loose standard and many modified versions exist including the option for an incremental AqB or sin/cos interface. In this implementation absolute position is only read at startup.

▶Adopt elastic soft connection shall be applied between encoder shaft and output shaft of user end to avoid damage of encoder shaft system due to serial movement and run out of user shaft.
▶Please pay attention to the allowable axle load during installation.
▶Make Sure that the difference Between Axial Degree of encoder shaft and user output shaft shall be no more than 0.20mm, and the deviation angle with axis shall be less than 1.5 °.
▶Try to avoid knocking and falling collision during installation;
▶Do not connect the power line and the ground wire in reverse.
▶The GND wire shall be as thick as possible, generally larger than φ 3.
▶Output lines of encoder shall not be overlapped with each other to avoid damaging output circuit.
▶Signal line of encoder shall not be connected to DC power supply or AC current to avoid damaging output circuit.
▶The motor and other equipment connected to the encoder shall be well grounded without static electricity.
▶Shielded cable shall be used for wiring.
▶Before starting the machine, carefully check whether the wiring is correct.
▶During long-distance transmission, the signal attenuation factor shall be considered, and the output mode with low output impedance and strong anti-interference ability shall be selected.
▶Avoid using in strong electromagnetic wave environment.
Five steps let you know how to select your encoder:
1.If you’ve already used encoders with other brands, plz feel free to send us the information of the brand info and encoder info, like model no, etc, our engineer will advise you with our euqivalent replacement at a high cost performance;
2.If you want to find an encoder for your application, plz first select encoder type: 1) Incremental encoder 2) Absolute encoder 3) Draw Wire Sensors 4) Manual Pluse Generator
3. Choose your output format(NPN/PNP/LINE DRIVER/PUSH PULL for incremental encoder) or interfaces(Parallel, SSI, BISS, Modbus, CANopen, Profibus, DeviceNET, Profinet, EtherCAT, Power Link, Modbus TCP);
4. Select the resolution of the encoder, Max.50000ppr for Gertech incremental encoder, Max.29bits for Gertech Absolute Encoder;
5. Select the housing Dia and shaft dia. of the encoder;
