4.3.1. TWR-MC-LV3PH module
The 3-Phase Low-Voltage Motor Control module (
) is a peripheral Tower System
module, interchangeable across the Tower System. The phase voltage and current feedback signals are
provided. These signals enable a variety of algorithms to control the 3-phase PMSM and BLDC motors.
A high level of board protection (over-current, under-voltage, over-temperature) is provided by the
MC33937 pre-driver. Before you insert the TWR-MC-LV3PH module into the Tower System, ensure
that the jumpers on your TWR-MC-LV3PH module are configured as follows:
