    Default Regarding encoder input to kflop

    Dear all


    Presently we are using KFLOP board and KMOTION. And we need to find the simple Encoders. For Finding the Encoders we need to know:*


    1. what are the Communication Protocols supports KFLOP board and KMOTION for interfacing the Encoders?

    2. How many Encoders we can interface which supports KFLOP & KMOTION?

    3. Which type of Encoder interfacing you will suggest for the KFLOP?

    *

    4.**Can we use EnDat 2.2 – Bidirectional Interface Type and TTL interface Type?


    Regards

    Hi Amit,

    what are the Communication Protocols supports KFLOP board and KMOTION for interfacing the Encoders?
    KFLOP only directly supports digital incremental encoders. See:
    http://dynomotion.com/faq.html#Encoders



    How many Encoders we can interface which supports KFLOP & KMOTION?
    KFLOP has 8 encoder inputs. There are some pinout limitations based on your configuration. The Encoder input pins normally on JP7 and JP5 can be multiplexed over to KFLOP JP4 and JP6. See the MuxEncoders.c example.

    Which type of Encoder interfacing you will suggest for the KFLOP?
    Differential digital incremental quadrature encoders

    Can we use EnDat 2.2 – Bidirectional Interface Type and TTL interface Type?
    No. Except sometimes they may include incremental quadrature signals.

    Hi Tom,

    Thanks for the information.

    As i was planning to use the following series of encoder from heidenhain.

    LC415/ LC485/ LF485/ LS487

    https://www.heidenhain.com/en_US/pro...lc-400-series/
    https://www.heidenhain.com/en_US/pro...-tools/lf-485/
    https://www.heidenhain.com/en_US/pro...ls-400-series/

    Please help me out with

    1. How to use the above encoders with the KLFOP/KANALOG ?

    2. Are these encoders compatible with KFLOP/KANALOG Board ?

    Waiting for your kind reply.

    Regards

    Amit Kumar

    Hi Amit,

    The encoders with the Incremental signals TTL would be compatible with KFLOP/Kanalog.

    From the Heidenhain Manuual:

    Regarding encoder input to kflop-heidmanual-png

    Connect:

    Heidenhain Ua1 to Kanalog A+
    Heidenhain Ua2 to Kanalog B+
    Heidenhain /Ua1 to Kanalog A-
    Heidenhain /Ua2 to Kanalog B-

    if the reference mark (Ua0 /Ua0) is required it may be connected to any spare A or B input

    KFLOP/Kanalog inputs have a max count rate of 1000000 quadrature counts per second. So for example if the resolution is 1um the max velocity would be 1 m/sec.

    Hi Tom,

    Thanks for your reply.

    I will connect that encoder to Kanalog and will try to run.

    And also let you know if any problem occurs.

    Regards

    Amit Kumar
