Introduction
The control parameters fields allow you to define the maximum speed and the maximum acceleration of the axes control.
NOTE: the terms speed and frequency are used interchangeably to characterize the ideas of speed.
Control parameters selection screen
The control parameters selection screen for the translator is as follows:
Description
Two fields are to be completed.
Selection
Meaning
Max. speed
The maximum speed (frequency) depends on the translator – motor – moving part as a whole.
The pulse generation circuit has a resolution of 1024 pulses on the frequency dynamic (zero frequency included).
The selection of a maximum speed has an influence on the frequency resolution of the channel. The following list gives the frequency resolution (Minimum Frequency) for a given max. frequency interval:
  • [1 Hz …936 Hz] mini frequency 0.92 Hz
  • [937 Hz …1873 Hz] mini frequency 1.83 Hz
  • [1874 Hz …4682 Hz] mini frequency 4.58 Hz
  • [4683 Hz …9365 Hz] mini frequency 9.16 Hz
  • [9366 Hz …46829 Hz] mini frequence 45.78 Hz
  • [46830 Hz …93658 Hz] mini frequence 91.55 Hz
  • [93659 Hz … 187316 Hz] mini frequency 183.11 Hz
Example: for a max. frequency of 20 KHz, the resolution (Min. Frequency) is 45.78 Hz.
Max. acc.
The effective acceleration of the axis that is defined in adjustment, must always be less than or equal to the maximum acceleration defined in the configuration.
The TSX CFY 11 and 21 modules are capable of modifying the rate of acceleration or deceleration every 5 ms. The dynamic resolution is 63 point, which means that when the selected unit of acceleration is the Hertz/s, in a given interval of maximum speed the acceleration can be between 1 and 63 times the minimum acceleration. The following list gives the authorized minimum accelerations for a given speed interval:
  • [1 Hz …936 Hz] minimum acceleration 183 Hz/s
  • [937 Hz …1873 Hz] minimum acceleration 366 Hz/s
  • [1874 Hz …4682 Hz] minimum acceleration 916 Hz/s
  • [4683 Hz,9365 Hz] minimum acceleration 1831 Hz/s
  • [9366 Hz,46829 Hz] minimum acceleration 9155 Hz/s
  • [46830 Hz …93658 Hz] minimum acceleration 18311 Hz/s
  • [93659 Hz …187316 Hz] minimum acceleration 36621 Hz/s
When acceleration is given in ms, the maximum acceleration corresponds to the minimum time taken to reach maximum speed when accelerating from the start stop frequency (SS_FREQ).
