4. Usage
4.1 Flash Writing
This product is equipped with an on-board emulator circuit (flash programming circuit), which enables flash writing
without preparing a separate tool product. Connect the USB cable to CN13 (USB mini B connector) of the CPU card
and the USB connector of the PC, and write using an application such as Renesas Flash Programmer or e2studio. When
using Renesas Flash Programmer or e2studio, the on-board emulator circuit will be recognized as E2Lite, so make the
connection settings accordingly.
For details on how to use each application, please refer to the respective user's manual.
Figure 4-1 Cable connection for flash writing
4.2 Connecting CPU Card
Preparation
Prepare the following
・Stabilized power supply: Output voltage of DC24[V] or more, current limit of 1[A] can be set.
・INV-BRD: INV-BRD(RTK0EM0000B10020BJ) included in Evaluation System for BLDC
Motor or INV-BRD (RTK0EM0000B11020BJ) included in Evaluation System for
Stepping Motor with Resolver
・Power supply cable: Cables capable of carrying a current of 1[A] or more
Make sure that the INV-BRD is not powered on, and connect this product.

4.3 Connecting Motor and Board
This product is equipped with an encoder signal input connector (CN4) and a resolver connector (CN14). Connect to the
motor according to the sample code you have written in flash.
Also, connect the motor to the motor connection connector (CN2) on the INV-BRD.
Figure 4-3 Motor and board Connection
4.4 Connecting Power Supply
The INV-BRD provides a terminal block (CN1) as a connector for supplying power to the board. Connect the positive
output of the stabilized power supply to pin 1 ("+" silk) of CN1 and the negative output to pin 2 ("-" silk) with a cable.

4.5 Operation
The operation of the CPU card depends on the sample code you have written. Please refer to the application note
attached to the sample code for specific operation and motor control methods.
4.6 In Case of Abnormal Odor, Smoke, Abnormal Sound, Overheating, Etc.
If any abnormality (strange odor, smoke, noise, heat, etc.) occurs, immediately turn off the stabilizing power supply and
shut off the current flowing into the inverter.

5. Functions
5.1 Power Supply
The product does not have a dedicated power supply connector. When connected to the INV-BRD, power is supplied
from INV-BRD. When not connected to the INV-BRD, power can be supplied from USB connector. When connected
to INV-BRD, power is supplied from INV-BRD, so power supply from USB connector is not allowed.
5.2 Emulator on Board
The E2 On-Board (E2OB) onboard emulator circuit is equipped in this product, and the RX72M program can be
rewritten using the E2OB. When connecting this product to the PC with USB connectors, the program can be rewritten.
The E2OB functions as an emulator equivalent to E2Lite, so when connecting from the integrated development
environment or Renesas Flash Programmer, set the emulator (tool) type to "E2Lite," the communication interface to
"FINE," and the power supply to "Do not supply.
If you want to use only power supply from USB connector without using E2OB function, remove the short jumper of
JP2 and JP3 and leave them open.
5.3 Connecting the Inverter Board
The product connects to the INV-BRD via the inverter board connectors (CN1 and CN2). Table 5-1 and Table 5-2 list
the pin assignments of the inverter board connectors.
