Operation
6.6 PROFIBUS
Speed setpoint (N_Set_A)
● Speed setpoint with 16-bit resolution incl. sign bit.
● Bit 15 determines the setpoint sign:
● The speed setpoint is normalized via parameter p2000.
Speed setpoint (N_Set_B)
● Speed setpoint with 32-bit resolution incl. sign bit.
● Bit 31 determines the setpoint sign:
● The speed setpoint is normalized via parameter p2000.
PCS7-specific setpoints (PCS7 x)
Depending on the configuration, KP adaptation values for the speed controller and
acceleration values or other setpoints, for example, are transferred here. Depending on their
application, these variables are generally normalized via parameters p2000 to p2004.

– Bit = 0 -> positive setpoint
– Bit = 1 -> negative setpoint
N_set_A = 4000 hex or 16384 dec = speed in p2000
– Bit = 0 -> positive setpoint
– Bit = 1 -> negative setpoint
N_set_B = 4000 0000 hex or 1073741824 dec = speed in p2000
