What is the reference positive direction of pmsm model in simscape with delta-wound configuration

I want to design a svpwm block to control the pmsm model and i need the reference positive direction of the machine. There is a clear diagram in help document for wye-wound configuration, but delta-wound configuration is not clear. How can i find the reference positive direction for delta-wound configuration?

The reference is the same. In delta-wound configuration we have line voltages which are defined as Vab, Vbc, Vca. From the control point of view there is not much difference between wye and delta but some inputs are not directly available. Line currents must be converter to phase current and an offset is need in the electrical angle used to compute dq currents.

Check out this example where you can switch beetween wye and delta using hyperlinks:
