Descriptions of functions
10.2 PROFIBUS
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.
Actual torque value (MACT, MACT_SMOOTH)
● Actual torque value with 16-bit resolution incl. sign bit
● Bit 15 determines the actual value sign:
● The actual torque value is scaled using parameter p2003.
Actual power value (PACT, PACT_SMOOTH)
● Actual power value with 16-bit resolution incl. sign bit
● Bit 15 determines the actual value sign:
● The actual power value is scaled using parameter p2004.
Alarm code (ALARM_CODE)
The number of the current alarm and the last alarm to occur are output here. Decimal
notation is used (i.e. value 7910 dec = A07910 (motor overtemperature)).
Fault code (FAULT_CODE)
The number of the oldest fault still active is output here. Decimal notation is used (i.e. value
7860 dec = fault F07860 (external fault 1)).

– 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
– Bit = 0 → positive actual value
– Bit = 1 → negative actual value
M_act = 4000 hex or 16384 dec = torque in p2003
– Bit = 0 → positive actual value
– Bit = 1 → negative actual value
P_act = 4000 hex or 16384 dec = power in p2004
