NSOLL_A (speed setpoint A (16-bit))
● Speed setpoint with a 16-bit resolution with sign bit.
● Bit 15 determines the sign of the setpoint:
● The speed is normalized via p2000.
NSOLL_B (speed setpoint B (32-bit))
● Speed setpoint with a 32-bit resolution with sign bit.
● Bit 31 determines the sign of the setpoint:
● The speed is normalized via p2000.
