Motor control operations

7.7.2

Specific jumper settings

Set-up the board as per the instructions in Section 7.4.12 (bus voltage between 9 and 28 V)

and Section 7.4.13.

Set-up the board as per Table 21.

7.7.3

LED action after power-on

Turn on the power supply. For this demonstration the power supply output voltage should be

set to 30 Vdc and the current limitation of the power supply should be set to 4 A.

After power-on, the control board LEDs should blink green and red alternatingly, signaling

that the firmware has started to run. After a while a green LED stays on indicating an "idle"

state.

7.7.4

Setting the potentiometers

Before running the motor the two potentiometers P1 and P3 must be set (see Table 22 for

the correct configuration).

7.7.5

Running the motor (LED action)

Push the Start/Stop button. After pushing the button, the LEDs toggle from green to red to

indicate the "run" state. Turn P1 in a clockwise direction. Keeping P1 fixed, turn P3 in a

clockwise direction until the motor runs.
