3 Jumpers and Switches

This chapter describes the jumpers and potentiometers to configure the various features of

the evaluation board. The default settings are shaded in the following tables.

3.1 Operating Mode

JP18 is used to select between serial Flash programming (UART0) and normal run mode.

3.2 Power Supply (JP: 13, 14, 28, 29, 31, 32, 63)

The evaluation board supports a variety of different input voltages. The regulator input for

MCU and logic supply can be provided either by a separate power input (X6), by the gate

driver supply voltage or it can be connected directly to the DC bus. The supply voltage for

the gate drive circuits must be in the range of 10-20V and can be derived either from the DC

bus or X6. A 15V voltage regulator can be inserted in case the used input voltage is higher

than 20V.

The UART and CAN interfaces can be optically isolated. Therefore, a DC-DC converter and

optocouplers are supplied on the board. They are placed in sockets, and can be bypassed

when not present.

JP13 Vcc_COM = VCC5

This jumper connects the transceiver supplies with the MCU supply when no DC-DC

converter is used (no galvanic decoupling)

JP14 GND_COM = GND

This jumper connects the transceiver ground with the MCU ground when no DC-DC

converter is used (no galvanic decoupling)

JP28 VCC15V Source

This jumper selects whether the gate driver supply voltage is fed from the 15V

voltage regulator or directly from the DC bus voltage

JP29 P_connect

This jumper can be used to connect the DC bus and gate driver supply to the supply

input X6. This can be useful when a small motor is used and the entire system is

from X6 and only the DC bus by J5 (default).

JP31 Power

This jumper can be used to switch the logic supply on and off.
