Figure 21 Three input thresholds configuration for VSP analog input control mode For Analog VSP control input mode, the motor speed can be calculated by measuring the frequency of PGOUT signal output of control IC IMC101T-T038. And the pulse generation number per revolution for motor can be configured in MCEWizard as shown in Figure 22. Figure 22 User Manual PG Pulse Per Revolution configuration 23 of 32 Revision 1.4 2018-03-29 EVAL-M1-101T User Manual iMOTIONTM Modular Application Design Kit Hardware description of EVAL-M1-101T Motor speed can be calculated as shown below. () = () For example, PGOUT frequency is about 80 Hz and Pulse per Revolution is 6, and then the motor speed will be 800 RPM. By default, VDD is 3.3V for EVAL-M1-101T. The input of VSP and PGOUT (pulse generation output) should be limited within the voltage range of 0 and 3.3V. While for some application, PGOUT should be connected to speed measurement circuit. The evaluation board EVAL-M1-101T provides FG (Frequency Generation) signal with an open drain structure controlled by PGOUT as shown in Figure 23. And FG signal can be pull up to 30V. The frequency of FG is the same as PGOUT, and the calculation equation for motor speed is the same.
