RSM-100 is a unit that measures the angle of the rotation axis by measuring the signals branched from the resolver signal line of a resolver measurement system consisting of an amplitude modulation type resolver and resolver digital converter(RDC).
It also outputs isolated A, B, and Z phase signals equivalent to encoder converted by RDC, and resolver signals such as excitation (EXC),sine(SIN),and cosine(COS)signals.
For the Z phase signal, electrical angle output and mechanical angle output can be selected.
・Capable of detecting resolver signals in the control state without affecting control or connected measuring instruments.
・R/D conversion and analog voltage output of resolver signal detected by branching
・Resolver shaft angle multiplication is compatible with ×1 to ×20
・Compatible up to 60000r/min(electrical angle)
■ Input the signal of this device to an analyzer or power analyzer and use it as a rotation signal
■ Input the instrument’s signal to an oscilloscope and check the waveform.
