Significance Description P No.
0 1 DC braking active --
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
6 1 |n_act| ≧ r1119 Speed setpoint reached
7 1 DC link voltage ≦ p2172 Actual DC link voltage ≦ threshold value
8 1 DC link voltage > p2172 Actual DC link voltage > threshold value
9 1 Ramping completed Ramp-function generator is not active.
