NOTES
190° orthogonal signals = Sin θ, Cos θ (Resolver) = PH/IP4 and PH/IP1.
2Three phase, 120°, three-wire signals = Cos θ, Cos (θ + 120°), Cos (θ + 240°).
= PH/IP1, PH/IP2, PH/IP3
High Level = PH/IPH1, PH/IPH2, PH/IPH3.
3Three Phase, 120°, two-wire signals = Cos (θ + 120°), Cos (θ + 240°) =
PH/IP2, PH/IP3.
In all cases where any of the input Pins 11 through 17 are not used, they must
be left unconnected.
