Hall Sensor Signal Input

This product is provided with a terminal for Hall sensor signal input. The signal input to this product is input to the
RX72M via a 5V pull-up, RC filter, and level shifter. Table 5-5 lists the pin assignments of the Hall sensor signal input
connector.

5.6

Encoder Signal Input

The product is equipped with an encoder signal input connector. Using this connector, you can input the encoder signal
to the RX72M. The signals are pulled up to 5 V and passed through RC filters before being input to the RX72M. Table
5-6 lists the pin assignments of the signal input connector.

Resolver Signal

This product is equipped with a resolver digital converter IC (RDC IC), which converts the analog signal output of the
resolver into a phase modulated digital signal output. For specifications of the RDC IC, refer to the RDC IC User's
Manual (r03uz002).
The connector for connecting the resolver is a plug/socket type and can be easily removed. The location of the resolver
connector (CN14) is shown in Figure 5-1, and the pin assignment of it is shown in Table 5-7.
