NSET_B (speed setpoint B (32-bit))

● Speed setpoint with a 32-bit resolution with sign bit.

● Bit 31 determines the sign of the setpoint:

– Bit = 0 → Positive setpoint

– Bit = 1 → Negative setpoint

● The speed is normalized via p2000.

NSET_B = 4000 0000 hex or 1 073 741 824 dec ≐ speed in p2000

Note

Operation of motors in the field-weakening range

If the motors are to be operated in the field-weakening range > 2:1, the value of parameter

p2000 must be set ≤ 1/2 x maximum speed of the drive object.
