Hardware settings for “Field Oriented Control” (FOC) in

single-shunt topology current reading configuration

To drive any motor, the user must ensure that:

●

The motor control demonstration board is driven by a control board that provides the

six output signals required to drive the three-phase power stage

●

The motor is connected to the J2 motor output connector

●

If using an encoder or Hall sensor connection, it is connected to connector J4

●

If using a tachometer connection, it is connected to connector J8

●

If using the brake control feature, connect a dissipative power load to J6 connector

Table 4 below shows the jumper settings for any high-voltage motors in single-shunt FOC

configuration. Please confirm that the demonstration board input voltage is in the range of

125 VDC to 400 VDC or 90 VAC to 285 VAC. If the voltage doubler is applied, the input

voltage must be in the range of 65 VAC to 145 VAC.
