UM0428 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
Present
(1)
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 Present
(1)
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
