Sensor voltage setting

W6 sets the voltage reference supplied to the Hall sensor or to the Encoder.

If W6 is set between 2-3, +5 V is supplied to the sensor.

If W6 is set between 1-2, the same voltage of the microcontroller is supplied to the sensor

(+5 or +3.3 depending W13).

For the remaining settings follow the description in Table 6.

Board connections

After the board has been configured the system can be set up as shown in Figure 12. This

configuration is called “running configuration”. The control board must be preventively

configured. (see control board user manual).

1.

Connect the insulated high voltage power supply to the J6 connector of STEVAL-

IHM011V1 (Pin 2-3).

2.

Connect the 34-pin flat cable between the two MC connectors: J4 of Control board and

J3 of power board.

3.

Connect the phases of the motor to the power board J4 connector and, if it is required,

connect the sensor signal to the Tachometer connector J2 or Hall Sensor/Encoder

connector J1 based on the sensor present inside the motor and driving strategy (see

control board user manual).

9

If it is required, connect a power supply with lower voltage output. For instance Ametek

motor requires the use of a power supply up to 30 V max.
