Note:

If an error message appears, make sure that the inDART-STX board is connected to the

ControlBDST7MC2 control board and that the control board is well supplied.

After programming, check the action of the LED to verify that the firmware has been

correctly downloaded (see Section 7.5.3, Section 7.6.3, and Section 7.7.3 ).

7.4.12

Configuring the DC input range

Before supplying the board with the bus voltage, it must be configured by setting the J22,

J23, J24, J27 and J8 jumpers to the correct position. Refer to Table 4 to configure the

jumper based on the DC input range

and keep the J8 jumper between 1-2.

7.4.13

Jumper settings table

Note:

The default configuration is indicated with (*) in Table 12.

7.4.14

Board connection

After the board has been programmed, the system can be configured as shown in

Figure 22. This configuration is called a running configuration. Remove the ICC flat cable

from the board if present.

Connect the insulated DC power supply to the J5 connector of STEVAL-IHM015V1,

following the serigraphy for polarity.

Connect the phases of the motor to the J10 connector of the board and if required,

connect the sensor signal to the hall sensor connector J14.

Description

Open

Disable the auxiliary Flash memory. The debug feature can be enabled.

Closed(*)

Enable the auxiliary Flash memory. The debug feature cannot be enabled.

Open

Disable the current reference generated by PWMV. The debug feature can be enabled

(this setting is not allowed when BLDC (trapezoidal) driving has been selected).

Closed(*)

Enable the current reference generated by PWMV. The debug features cannot be

enabled.

Between 1-2

Adjustable – the current reference value (MCCREF) is set by potentiometer P4. Only for

BLDC (trapezoidal) driving.

Between 2-3(*)

Variable – the current reference value (MCCREF) is driven by the microcontroller PWM-V.

Only for BLDC (trapezoidal) driving.

Open

No current reference is required. For PMAC motor (sinewave) driving.

J21

Open(*)

The threshold voltage used for BEMF detection is set internally by the microcontroller

firmware. This option should be selected for the ST BEMF detecting strategy.

Between 1-2

The threshold voltage used for BEMF detection is derived from the phase voltage value.

This option should be selected for the GE BEMF detecting strategy.

Between 2-3

The threshold voltage used for BEMF detection is derived from the bus voltage. This

option should be selected for the GE BEMF detecting strategy.
