Speed setpoint (N_Set_A)
● Speed setpoint with 16-bit resolution incl. sign bit.
● Bit 15 determines the setpoint sign:
– Bit = 0 -> positive setpoint
– Bit = 1 -> negative setpoint
● The speed setpoint is normalized via parameter p2000.
N_set_A = 4000 hex or 16384 dec = speed in p2000
Speed setpoint (N_Set_B)
● Speed setpoint with 32-bit resolution incl. sign bit.
● Bit 31 determines the setpoint sign:
– Bit = 0 -> positive setpoint
– Bit = 1 -> negative setpoint
● The speed setpoint is normalized via parameter p2000.
N_set_B = 4000 0000 hex or 1073741824 dec = speed in 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.
