2. Board settings and connections
Make the following settings and connections.
Turn potentiometer VR1 counterclockwise to the end, so that the motor does not rotate when the power is
■
turned on.
When using a shunt resistor on this board, connect J3 (VM connection for external MOSFET) and J5
■
(GND connection for external MOSFET) to the power and GND terminal of the external MOSFET board.
Connect the CN_INV connector on the board to the following terminal on the external MOSFET board.
■
Note.1
Gate drive signal terminal (UH, UL, VH, VL, WH, WL)
o
o Motor output terminal (U, V, W)
o Current detection signal terminal (ISENP / ISENN): When using a current detection resistor
on the external board
o Thermistor connection terminal (P21/GND): When using a thermistor on an external
MOSFET board
Connect the external MOSFET board and motor
■
Connect the CN_HALL connector of the board and the HALL terminal of the motor
■
When using the included motor, connect 24V to the VM input terminal (J4) and connect the GND input
■
terminal (J6) to GND.
included motor
Note.1 Please prepare the external MOSFET board by yourself.
Note.2 Each GND terminal of CN_INV is GND for thermistor and GND for shield of ISENP / ISENN wiring.If the GND of
CN_INV is used for the GND for MOSFET, it may be damaged by the over current etc.
Note 3 When connecting a user-prepared motor, a supply voltage of up to 42 V is available to match the motor's operating
voltage. Select MOSFETs with a withstand voltage that takes into account the amplitude of the supply voltage.
Attention!
Renesas will not be liable for any damages such as board failure or injury resulting from the change. Please be
safe to change and configure the board at your own risk.
