9.5.5.3 PROFIdrive Reference Speed Setpoint and Actual Speed
The speed setpoint value, NSOLL_A, is the commanded speed reference (normalized) sent from the
controller to the inverter. Similarly, the speed actual value, NIST_A, is the actual operating speed
(normalized) of the inverter sent back to the controller. As the inverter natively operates in units of Hz,
the following conversion equations are applied within the interface card:
NSOLL_A: The inverter reference speed setpoint is a normalized value. The interface card applies the
conversion indicated in Equation 8 in order to determine the appropriate speed command to be written to
function code S01 (frequency command (p.u.)).

= Equation 8
NIST_A: The inverter operating actual speed is a normalized value that is calculated from inverter
function code M06 (output frequency (p.u.)). The interface card applies the conversion indicated in
Equation 9 in order to determine the appropriate operating speed actual (normalized).
