(19-1) and S select the interface of a switch B (19-2) to disconnect；In the operational mode, sensor selects a switch A (19-1) with being connected S
Or S selects one of interface of a switch B (19-2) to connect；Only two on-off circuit work, one of switch will every time
Sensor is connected to S and selects a switch A (19-1), and another switch connects the sensor to S and selects a switch B (19-2)；Measurement is set
During standby work, select on-off circuit, S a switch A (19-1) and S to select the control of a switch B (19-2) by microprocessor, select
One sensor is connected to resolver 2 (18-2), selects another sensor to be connected to reverse signal isolator (17).
