Clockwise turn: Motor shaft rotates clockwise.
Counterclockwise turn: Motor shaft rotates counterclockwise.
SW1
ON: Motor rotation enabled
OFF: Motor rotation disabled
SW2
Cancels error state: OFF → ON → OFF after an error:
LED1
ON: SW1 ON and normal state.
OFF: SW1 OFF or error state.
LED2
ON: error state.
OFF: normal state.
5.2.2 Canceling an Error State
If an error occurs, LED2 lights on the INV-BRD and the product, and motor rotation stops. To recover, it is necessary to
turn off toggle switch SW1 and turn on toggle switch SW2 on the INV-BRD, and then turn off toggle switch SW2 again.
5.3 In Case of Abnormal Odor, Smoke, Abnormal Sound, Overheating, Etc.
The INV-BRD is equipped with a toggle switch (S1) to cut off the flow of current to the inverter. If an abnormal
condition (such as abnormal odor, smoke, abnormal sound, or overheating) occurs, turn off S1 to cut off current flow to
the inverter.

6. Functions
6.1 Power Supply
The product does not have a dedicated power supply connector. When connected to the INV-BRD it draws power via
the connector. When not connected to the INV-BRD, it can draw power via the Emulator connector. The product is not
allowed to draw power via the Emulator connector when it is connected to the INV-BRD.
6.2 Connecting the Emulator
The E1/E2 Lite on-chip debugging emulator from Renesas Electronics is used to write software (program) to the flash
memory of the RX72T. Software will be downloaded into the product via E1 or E2 Lite. It is also necessary to make the
settings shown in Table 6-1 in the integrated development environment to enable the emulator to supply power to the
product. Table 6-2 lists the pin assignments of the Emulator connector.

6.7 Connecting the Extender Board
This product is equipped with two Extender board Connector. This connector can connect Extender Board
(RTK0EM0000Z02000BJ) via the cable. This makes it possible to control three INV-BRDs. In other words, this
product can drive three motors. Table 6-10 lists the pin assignments of the 2nd Extender board Connector.
Table 6-11 lists the pin assignments of the 3rd Extender board Connector. Note that the pin assignments of CND are
different from those of CNC and that some pins of CND are pull-upped because of sharing the pins with CN7.

6.9 Reset Circuit
The product is equipped with a reset circuit for resetting the microcontroller at power-on reset and external reset. To
apply an external reset to the microcontroller, press the pushbutton (SW1).
6.10 Crystal Resonator
This product is mounted crystal oscillator (Y1) on 8MHz.
6.11 LEDs
Two LEDs are mounted on the product for use in debugging programs and general system applications. Each turns on
when the output on the corresponding port is low-level and turns off when the output is high-level. Table 6-13 lists the
pin assignments corresponding to the LEDs.
