Schematics

The schematics of IMD112T control board, EVAL-M7-D112, include digital Hall feedback inputs and analog
position feedback input terminals. The onboard debug circuitry is placed on the control board and users can
conveniently tune the board using a USB cable. The onboard debug circuitry has an isolation function between
the computer's USB port and the IMD112T control board. An optional communication interface, iMOTION
connector (J5) is also on the board. The two resistors, R110 and R111, should be removed when using the
iMOTION Link debug tool.
