TMS320F28377D: What is "Base_Speed" means in M-method velocimetry?

Part Number: TMS320F28377D
Other Parts Discussed in Thread: C2000WARE

Dear team：

In the encoder M method, there is a formula: speed = Base_Speed* (x2-x1)/4000. So how do I determine this Base_Speed when actually calculating it?

Best regards

    Hi,

    I believe you are referring to the eQEP example files.
    Please refer to 
    C:\ti\c2000\C2000Ware_2_00_00_02\device_support\f2837xd\examples\cpu1\eqep_pos_speed\cpu01
    Example_posspeed.xls
    This file has definitions for all parameters. Base RPM is defined as maximum required speed 6000rpm in the example.
