Figure 21-11. Current Flow when STEP = 0, DCOIL = 1, ITG = 0, RCIR = 0
Figure 21-12 shows the current flow in the SINx and COSx H-bridges when STEP = 1, DCOIL = 1,
ITG = 0 and RCIR = 1.
Figure 21-12. Current Flow when STEP = 1, DCOIL = 1, ITG = 0, RCIR = 1
Figure 21-13 shows the current flow in the SINx and COSx H-bridges when STEP = 2, DCOIL = 1 and
ITG = 1.
