Feedback connector

The use of a flat cable is recommended to keep the signals shielded.

Eval 6205 configuration:

JP1: Place JP1 in the INT position to enable the on-board 5VDC supply.

JP2 and JP3: Install JP2 and JP3 to assure proper timing operation of the L6205's internal

high side overcurrent protection.

JP4 and JP5: Install JP4 and JP5 to configure the Vref circuits.

Supply the power to eval 6205 through connector CN1.

Connect the DC motor through CN3 connector (OUT1A and OUT2A).

Refer to the L6205 datasheet for more detailed information

Note:

For each EVAL 6205 board eMotion kit allows to connect and control one motor.

Eval 6235 configuration:

JP1 and JP2: Install JP1 and JP2 to enable the on-board 5VDC supply.

SWITCHES: Place all four switches in the OFF position.

HALL SENSORS: Connect the Hall sensors of the BLDC motor at CN5. Connect the power

supply wires from the Hall sensors at pins GND and 5V. Connect H1, H2, and H3 signals to

their respective pins.

Motor Connections: Connect the three motor armature wires at CN3 being careful to match

the phasing to the Hall sensor connections.

Refer to L6235 datasheet for more detailed information.

To connect the power spin boards use a flat 34-pin cables and before power on all the

systems (motors and boards) please refer to Section 6.1: Hardware issues on page 26.

Control operations

Before starting to use the motors, ensure that all the connection are correctly established.

Turn on MDK-ST10 and later turn the power of motors.

Open Loop

For a DC: enable the driver and modify the PWM in terms of DUTY % (depending on the

motor connection, a 0 value corresponds to either the minimum or the maximum speed).
