Signals and Raw Versus Physical Values

Table 5.  Signals and Physical Versus Raw Integer Values
Signal Name Description Raw Integer Values Equivalent Physical Value
Vu
Vv
Vw Space vector modulation voltages applied to motor terminals u, v and w. 0 to 3,125 -200 to +200 V
Iu
Iv
Iw Measured feedback currents. Iv is derived from Iu and Iw. -5,120 to +5,120 -1 to 1 A
Id
IdCommand
Iq
IqCommand FOC direct and quadrature currents and their commanded values. IdCommand=0 for a PMSM. -5, 120 to +5,120 -1 to 1 A
Speed
Speed Command Speed derived from encoder readings and its commanded value. -32,768 to +32,768 -2048 to +2048 rpm
Position PositionCommand Position derived from encoder reading, and its commanded value. 0 to 65,536 0 to 1rev
Vd
Vq FOC direct and quadrature voltages. The Voltage Output Limit also uses this scaling, but only takes positive values. -1,563 to +1,563 -200 V to +200 V
Vd_unfilt
Vq_unfilt Vd and Vq before the suppression filter (if your design includes vibration suppression) -1,563 to +1,563 -200 V to +200 V
