p2051[3] = r0053
1 1 = |n_act | > p1226 Absolute current speed > stationary
state detection
2 1 = |n_act | > p1080 Absolute actual speed > minimum
speed
3 1 = i_act ≧ p2170 Actual current ≥ current threshold
value
4 1 = |n_act | > p2155 Absolute actual speed > speed
threshold value 2
5 1 = |n_act | ≦ p2155 Absolute actual speed < speed
threshold value 2
