    GMA-D Series DeviceNet Interface Bus-Based Multi-turn Absolute Encoder

    GMA-D Series encoder is a DeviceNET interface cooper-gear-type mult-turn absolute encoder with housing Dia.:58mm; Solid Shaft Dia.:10mm, resolution: Max.29bits; This protocol is mainly used by Allan Bradley / Rockwell. DeviceNet uses the same physical layer as CAN, combined with CIP. The Communications and Information Protocol (CIP) is a communications protocol for transferring automation data between devices. Communication is also done by message telegrams (11 bits of identifier and 8 subsequent bytes).

    Controller Area NetworkCAN stands for Controller Area Network and was developed by the company Bosch for applications within the automobile area. In the meantime CAN has become increasingly used for industrial applications. CAN is a multi-masterable system, i.e. all users can access the bus at any time as long as it is free. CAN doesn’t operate with addresses but with message identifiers.
    Bus AccessAccess to the bus is performed according to the CSMA/CA principle (carrier sense multiple access with collision avoidance), i.e. each user listens if the bus is free, and if so, is allowed to send messages. If two users attempt to access the bus simultaneously, the one with the highest priority (lowest identifier) receives the permission to send. Users with lower priority interrupt their data transfer and will access the bus when it is free again. Messages can be received by every participant. Controlled by an acceptance filter the participant accepts only messages that are intended for it. POSITAL rotary encoders support two CAN protocols: CANopen and DeviceNet.
    Supported Telegram TypesWith a POSITAL rotary encoder this number is assigned with by numerical coded turn switches in the connection cap. The function code varies according to the type of message transmitted: PDOs (Process Data Objects) are needed for real time data exchange. Since this messages possess a high priority, the function code and therefore the identifier are low. SDOs (service data objects) are necessary for the bus node configuration (e.g. transfer of device parameters). Because these message telegrams are tranferred acyclicly (usually only while powering up the network), the priority is low.

    Ordering Code

    Dimensions

     

    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;
    Gertech is popular equivalent replacement for similar foreign products such as Sick/Heidenhain/Nemicon/Autonics/ Koyo/Omron/Baumer /Tamagawa/Hengstler /Trelectronic/Pepperl+Fuchs/Elco/Kuebler ,ETC.
