A100%00P1
B1100%10P2
B2100%−10P3
C33.3%00P4
D66.7%00P5
E100%−1−1P6

Output P1: normal state.
Output P2: armatures resistance increase.
Output P3: armatures resistance decrease.
Output P4: bus current is zero during four of all the six states of one cycle; one MOSFET break is possible.
Output P5: bus current is zero during four of all the six states of one cycle; one armature break is possible.
Output P6: interarmatures short.
