3. Configure hardware
3.1 Configuring the hardware
To configure the hardware, complete the following procedure:
- Assemble IGBT module with a water cooling jacket if desired and properly attach to DC-Link capacitor
positive and negative high-voltage supply connections across U, V, and W phases.
- Attach RDGD3100I3PH5EVB to the IGBT module. Ensure that all board socket connection pins are properly
seated onto the IGBT pin connections. The board socket pins are intended for easy attachment and detachment
to IGBT module without damaging IGBT connection pins.
- Connect motor:
- a. Connect the output of IGBT module each phase U, V, and W to each of the respective U, V, W connections on
the
desired three-phase motor.
- b. For running motor in closed-loop motor control, connect resolver signals from motor resolver connection
to
the resolver pin connections on the
RDGD3100I3PH5EVB. See schematics for J50 header signal connections on the RDGD3100I3PH5EVB board.
- c. For running motor in closed-loop motor control, connect current sensors from each phase U, V, and W
(current sensors are not included with RDGD3100I3PH5EVB) and connect the respective signals from the current
sensors to the phase current feedback pin connections of the RDGD3100I3PH5EVB. See schematics for J40 header
signal connections on the RDGD3100I3PH5EVB board.
- Connect DC power:
- a. Connect a low voltage DC power supply to the RDGD3100I3H5EVB at the VSUP connection terminal (12 V DC
with a minimum 1.0 A supply). Ensure that J100 jumper is in place.
- b. Connect a low voltage DC supply to MCU controller board and connect the USB cable from MCU controller to
the desired computer for software-driven motor control.
- c. Connect high voltage/high current DC supply (use recommended voltage and current for the desired motor) to
positive and negative connections on the DC-Link capacitor to supply three-phase motor DC link voltage.
- Attach 2x32 PCIe cable (X-S32SDEV-CON18) supplied with the kit to the RDGD3100I3PH5EVB and MCU controller
board such as the MPC5777C-DEVB. This cable is keyed and is compatible with interface port on MPC5777C-DEVB.
