Actual speed value (N_Act_A, N_Act_SMOOTH)
● Actual speed value with 16-bit resolution incl. sign bit.
● Bit 15 determines the actual value sign:
– Bit = 0 -> positive actual value
– Bit = 1 -> negative actual value
● The actual speed value is normalized via parameter p2000.
N_act_A = 4000 hex or 16384 dec = speed in p2000
Actual speed (N_act_B)
● Actual speed value with 32-bit resolution incl. sign bit.
● Bit 31 determines the actual value sign:
– Bit = 0 -> positive actual value
– Bit = 1 -> negative actual value
● The actual speed value is normalized via parameter p2000.
N_act_B = 4000 0000 hex or 1073741824 dec = speed in p2000
Actual current value (Ia_Act, Ia_Act_SMOOTH)
● Actual current value with 16-bit resolution
● The actual current value is normalized via parameter p2002.
Ia_act = 4000 hex or 16384 dec = current in p2002
