34Magtrol Model DSP7000 Dynamometer ControllerChapter3 – Installation/Con gurationSETUPFigure 3–27 RPM vs PPR ChartFigure 3–27 provides a reference for allowable maximum RPMs when using an encoder with a givenPPR. Theses combinations keep the input frequency within the allowable limits for the DSP7000.quad Deg is designed to be used with very slow RPM applications with a quadrature encoder in thesystem. The speed of the system is limited to 100 RPM. The pulse per revolution (ppr) can be setfrom 1000 to 99999 ppr. The angle to perform the measurement can be set from 10 to 90 degrees.The maximum frequency from the encoder can be as high as 200 khz.AI 1 is designed to take the analog voltage from the Io card associated with the channel being setupand use that analog voltage as the speed input. A scale factor can be applied to the input.1. Starting from main menu, press ShIFT.2. Press SETUP to display the setup menu.3. Select DYNo to display the dynamometer setup menu.4. Select ENCoDERS. The display should appear as follows:
