For motors with salient pole structures, aligning the motor BEMF voltage with the motor current may not achieve

the best efficiency. In these applications, the timing advance should be adjusted accordingly. Accomplish this by

operating the system at constant speed and load conditions and by adjusting tadv until the minimum current is

achieved.

Figure 28. Advance Time (tadv) Definition

The DRV10983-Q1 device has two options for adjusting the motor commutate advance time. When

CommAdvMode = 0, mode 0 is selected. When CommAdvMode = 1, mode 1 is selected.

Mode 0: tadv is maintained to be a fixed time relative to the estimated BEMF zero cross as determined by

Equation 5.

tadv = tSETTING

(5)

Mode 1: tadv is maintained to be a variable time relative to the estimated BEMF zero cross as determined by

Equation 6.

tadv = tSETTING × (U - BEMF) / U.

where

•

U is the phase voltage amplitude

•

BEMF is phase BEMF amplitude

(6)

tSETTING (in µs) is determined by the configuration of the TCtrlAdvShift [2:0] and TCtrlAdvValue [3:0] bits as

defined in Equation 7. For convenience, the available tSETTING values are provided in Table 6.

tSETTING = 2.5 µs × [TCtrlAdvValue[3:0]] << TCtrlAdvShift[2:0]
