Doc ID 15870 Rev 4

Table 6 below shows the jumper settings for three-shunt based FOC of any high-voltage

PMSM, BLDC, or AC IM motor. 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.

Table 7 shows jumper settings for three-shunt based FOC of any low-voltage PMSM or

BLDC. Please confirm that the input voltage of the demonstration board in this case is in the

range of 18 VDC to 35 VDC. If it is necessary to supply the motor with a voltage lower than

18 VDC, please remove the W3 jumper and connect the auxiliary voltage to the J3

connector.

In this configuration it may be necessary to modify R2, R4, and R7 resistors according to the

applied supply voltage.
