Current feedback configuration in MCEWizard for EVAL-M1-101TF and EVAL-M1-05-065D

2.4.3

Motor internal current feedback amplifier gain configuration

For the current feedback, the iMOTION™ controller on this board has the internal amplifier which has four
programmable gain settings: 1x, 3x, 6x and 12x.

The internal current-feedback amplifier gain can be configured in MCEWizard as shown in Figure 15.
