Hardware description of EVAL-M3-CM615PN

The high side resistors R23 and R24 for the DC bus sensing resistor divider on the controller board EVAL-M3-

CM615PN are 2000kΩ, and should be configured in MCEWizard as shown in Figure 20. For the low side resistor

value, please refer to the User Manual of the corresponding control board.

Motor External Current feedback configuration and calculation

The current input value is product of the shunt resistance in milliohms and gain of External current sense

amplifier for EVAL-M3-102T as shown in Figure 21.

Figure 21 Current shunt feedback and sample timing for EVAL-M3-102T

The External Amplifier Gain circuit can be found in the schematics or User Manual for the control board (For

example, EVAL-M3-102T see Figure 22).

Figure 22 depicts IU+ current feedback sensing circuity on EVAL-M3-102T evaluation board. Please note that the

default external amplification gain is less than 1 for current sense in this evaluation board.
