Current feedback configuration in MCEWizard for EVAL-M3-302F and EVAL-M3-CM615PN

6.1.3

Internal 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.
