flashes (1 Hz)

Configuration error, e.g.:
- Value for motor full steps is 0 (R33)
- Value for encoder increments is 0 (R34)
- Value for min. velocity v_min is 0 (R38)
- Value for max. velocity v_max is 0 (R39)
- Value for max. acceleration a_max is 0 (R40)
- Value for coil current I_S for a > a_th is 0 (R42)
- Value for coil current I_S with a ≤ a_th is 0 (R43)

Power (green)

off

flashes (1 Hz)

The current load angle (SB.3 to SB.1) is greater than the configured load angle threshold (R47).

Error B (red)

flashes (1 Hz)

Supply or load error
- Supply voltage (24 V_DC) too low (bit SW.9 in the status word is set)
- Open load at bridge A (bit SW.11 is set in the status word)
- Open load at bridge B (bit SW.12 is set in the status word)
- Overcurrent at bridge A (bit SW.13 is set in the status word)
- Overcurrent at bridge B (bit SW.11 is set in the status word)
