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
