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:
– Bit = 0 → Positive setpoint
– Bit = 1 → Negative setpoint
● The speed is normalized via p2000.
NSOLL_A = 4000 hex or 16384 dec ≐ speed in 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:
– Bit = 0 → Positive setpoint
– Bit = 1 → Negative setpoint
● The speed is normalized via p2000.
NSOLL_B = 4000 0000 hex or 1 073 741 824 dec ≐ speed in p2000
