NACT_A (Speed setpoint A (16 bit))

●Actual speed value with 16-bit resolution.

●The speed actual value is normalized in the same way as the setpoint (see NSOLL_A).

NACT_B (Speed setpoint B (32 bit))

●Actual speed value with 32-bit resolution.

●The speed actual value is normalized in the same way as the setpoint (see NSOLL_B).

Gn_ZSW (encoder n status word)

Gn_XIST1 (encoder n position actual value 1)

Gn_XIST2 (encoder n position actual value 2)

This process data belongs to the encoder interface.

ITIST_GLATT

The actual current value smoothed with p0045 is displayed.
