QUICK START GUIDE EPC9147A Interface Board for Motor Drive Board
EPC – POWER CONVERSION TECHNOLOGY LEADER | EPC-CO.COM | ©2021 | | 2
DESCRIPTION The EPC9147A board is an interface board that accepts the Microchip MA330031-2 Plug-In-Module (PIM), that is fitted with the dsPIC33EP256MC506 Digital Signal Processor (DSP), and interfaces to a 3-phase eGaN® FET/IC motor drive inverter board. This interface board allows users to utilize the existing Microchip motorBench® Development Suite resources to program the PIM that controls a motor powered by an eGaN FET/IC 3-phase inverter using sensorless field orientation control with space vector pulse width modulation.
Figure 1 shows an overview of the EPC9147A board detailing connections and various human interfaces that measures 99.3 mm x 68 mm (L x W). It is provided with a fully isolated micro-USB communications interface that is powered by the host computer on the isolated side and by the motor inverter on the non-isolated side.

The EPC9147A is includes a standard Microchip compatible programming port (J4), I2C expansion port (J8) and, a 40-pin card edge connector (J2) that interfaces the PWM, analog feedback signal, errors states and 3.3 V power to the motor drive inverter board as shown in figure 2.
The USB communication port is used to communicate with the PIM module that monitors various inverter operating conditions using X2C-Scope.The programming port is used to program the controller using MPLAB® X IDE or IPE and compatible programming devices.

HUMAN INTERFACE CONTROLS AND INDICATORS The EPC9147A has various human interface controls and indicators as shown in figure 1.
To operate the motor the following controls are available as push button or knob:
• Start/Stop – Starts and stops the motor from spinning toggle.• Direction – This button toggles the motor spin direction.• Speed – This knob changes the rotation speed of the motor.
There are also 4 LED indicators the help provide information on the status of the controller:
• Power LED (green) – The board has power. Power is provided by the motor drive inverter.
• Error LED (red)- Indicates some error has occurred. The operator can read the error based on the flashing codes of the debug LED or using motorBench® Development Suite.
• Debug LEDs (yellow and blue) - Indicates the code by a series of encoded flashes. Please refer to the Microchip manual for MCLV-2 for details on the codes.
There is a reset button that can be used to reset the processor to the power up state.
Warning: The human interface controls and knob, as well as the entire EPC9147A, are not isolated. The EPC9147A is referenced to Power Ground and extreme caution has to be observed when operating at high voltage.
Test PointsA number of test-points are available for measurement of various analog, error and PWM signals. Analog signals include voltage and current readings, input DC voltage to the drive, and current sense amplifier voltage reference. The operator is encouraged to read the motor drive inverter drive QSG carefully to determine the correct scaling factors. All three phases of the PWM signals are available as test points. An over-current error signal is also available as a test point. Two locations for ground connections for measurement purposes are available at TP4 and TP5.
Over-Current detectThe EPC9147A includes and overcurrent detect that is fed to the controller as a fault signal (OC_FLT). This signal will trigger if any motor current phase exceeds the preset voltage of 3.25 V. Refer to the motor drive inverter for the correct conversion of the current sense circuit to determine the correct current magnitude that will generate an over-current trip. Once an over-current is triggered, the OC_FLT signal will remain low for a short period of time, determined by the RC time constant of R5+R8 and C17. The behavior when the OC_FLT is asserted depends on the specific program that has been programmed in the PIM.
Monitoring Jumper SettingsThe EPC9147A is provided with a set of jumpers that can be used to change the monitoring connections. Table 1 provides a detailed list of the settings mapping and figure 3 shows this graphically.

QUICK START PROCEDURE Please check the following: https://epc-co.com/epc/Products/eGaNDriversandControllers.aspx for updates on compatible eGaN FET/IC inverters with reference settings for specific motors.
Motor Commissioning ProcedureIt is recommended to follow the detailed motor commissioning process for MCLV-2, provided by Microchip MotorBench® Development Suite when using the EPC9147A in conjunction with and compatible eGaN FET/IC 3-phase motor drive inverter. The procedure documented here provided as simple guide and example only.
1) Start MPLAB X, then select MCC to load the MPLAB X Code Configurator (MCC).
2) On MCC tree view in the left panel, scroll down until you find motor Bench® development and select it.
3) Once motor Bench development suite has loaded, select the Configure Tab and chose Board and expand it, then select the MCLV-2 board. The MCLV-2 settings can be used to configure the eGaN FET/IC based inverter to the motor selected.
4) An example is given in Table 7. Pay careful attention to the deadtime field as it tends to revert to 2µs, which is too long for GaN FET inverters. A dead time setting of 21 ns is recommended.
5) Customizable settings can be changed by selecting the “Show advanced parameters” checkbox. Customizable settings include: minimum velocity, maximum acceleration/deceleration, startup current, minimum acceleration time and, active damping (recommend using zero here).
6) After entering all the parameters, check that you get “Ready to Generate” on the tab above “Configure”. If not, recheck the parameter settings. If you get the “Ready to Generate” tab then proceed to select the Generate tab and allow MCC to generate the code. Once the code is generated, connect the ICD programmer to the EPC9147A board programming port (JX) and select the Program Icon. Make sure that the ICD can power up the EPC9147A and that the EPC9147A is not connected to other power supply.
Note: Every time you change Motor or load (e.g. from no load to dynamometer bench) it is important to regenerate the code with proper values. If you change motor section parameter, double check the board parameters. MPLAB X occasionally reverts them back to the default values of MCLV-2 that are not suitable for the GaN FET/IC inverter.
Warning: The motor parameters measurement feature of motorBench® Development Suite does not work by default on the EPC9147A.
