Motor control demonstration

19/27

If the STEVAL-IHM010V1 is used, Table 7 can be used to configure the jumper related to

the driving strategy.

W11

Between 1-2

If sensorless control is set (see W9), it connects motor phase C to MC connector through

R59-R60-R61-R62 feedback resistors. In this case the microcontroller internal comparator

is used to detect the BEMF.

Between 2-3

The external comparator U2C is used to detect the BEMF. If sensorless control is set (see

W9), it connects the output of U2C to MC connector.

Not present

Use this setting for sensored control (Tacho, Encoder, Hall)

W12

Present

It is used to connect Tachometer sensor signal, already conditioned, to "Measure Phase

C" pin of MC connector. W9 jumper must be not present.

Not Present

Tachometer input is not connected.

W13

Between 1-2

It sets Vdd_Micro value to +3.3 V.

Between 2-3

It sets Vdd_Micro value to +5 V.

Not present

Pin 28 of MC connector is not supplied

W14

Present

It connects the +5 V to pin 25 of MC connector.

Not present

Pin 25 of MC connector is not supplied.

W16

Between 1-2

Use this setting if the Mains is above 24 Vac. VIPer is used to obtain 15 V.

Between 2-3

Use this setting if the Mains is below 24 Vac. L7815 regulator is used to obtain 15 V.

Open

Leave open if +15 V DC external power supply is used.

W18

Connect the Diag signal of the driver to the Fault pin 1 of MC connector through the U12A

used to adapt voltage level.

Not Present

Fault pin 1 of MC connector is not connected.

W19

Connect the comparator U5A "Thermal Protection" to the shutdown pin of the driver. When

over temperature occurs based on U5A comparison (see Temp_Vref in the schematic) the

drivers are stopped.

W21

Not Present

Remove it to disconnect "Thermal Protection" measured by U5A with the shutdown pin of

the driver.

Between 1-2

Use this setting for shunt resistor feedback

Between 2-3

Use this setting for ICS feedback

W22

Between 1-2

Use this setting for shunt resistor feedback

Between 2-3

Use this setting for ICS feedback

W23

Between 1-2

Use this setting for shunt resistor feedback

Between 2-3

Use this setting for ICS feedback

W24

Open

Overvoltage threshold settings. Use this setting when the micro is supplied with 5 V

Closed

Use this setting when the micro is supplied with 3.3 V
