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

Gn_STW (encoder n control word)

This process data belongs to the encoder interface.

XERR (position deviation)

The position deviation for dynamic servo control (DSC) is transmitted via this setpoint.
