Table 12 - Resolver Sample Interval
Parameter 270 [Reslvr0 SpdRatio] specifies the speed ratio for the resolver
option card at port 0. The speed ratio comes from the following formula.
Speed ratio = electrical revolutions / mechanical revolutions = pole count / 2.
Parameter 271 [Reslvr0 Carrier] specifies the resolver carrier frequency for the
resolver option card at port 0.
Parameter 272 [Reslvr0 In Volts] specifies the resolver input voltage for the
resolver option card at port 0.
Parameter 273 [Rslvr0 XfrmRatio] specifies the resolver transform ratio for the
resolver option card at port 0.
Parameter 274 [Reslvr0 CableBal] specifies the resolver cable balance for the
resolver option card at port 0.
