Bit Meaning
9 Control request
"1" is always present
10 n setpoint reached or exceeded
Note:
The message is parameterized as follows: p50373 (threshold value), p50374 (hysteresis)
See FP8020 and FP2537
11 I or M limit not reached (when
p0922 = 1 or 352)
I or M limit not reached (when
p0922 = 20)
12 Holding brake released
(when p0922 = 1 or 352)
Reserved (when p0922 = 20)
13 Reserved
14 Motor rotates forward
(n_act ≥ 0)
15 Reserved
(when p0922 = 1 or 352)
CDS display
(when p0922 = 20)
Actual values
Actual speed value A 16-bit (NACT_A, NACT_SMOOTH)
● Actual speed value with 16-bit resolution incl. sign bit
● Bit 15 determines the actual value sign:
● The actual speed value is scaled using parameter p2000.
Actual current value (IAACT, IAACT_SMOOTH)
● Actual current value with 16-bit resolution
● The actual current value is scaled using parameter p2002.

0 I or M limit reached or exceeded
1 Holding brake is released
0 Holding brake is not released
1 Motor rotates forward (n_act ≥ 0)
0 Motor does not rotate forward (n_act < 0)
1 CDS selection bit 0 selected
0 CDS selection bit 0 not selected
– Bit = 0 → positive actual value
– Bit = 1 → negative actual value
N_act_A = 4000 hex or 16384 dec = speed in p2000
Ia_act = 4000 hex or 16384 dec = current in p2002
