LEDs D10, D11, and SW2, SW3, R28
At initial power on, LEDs D10 (Red) and D11 (Green) blink on and off at a fixed rate.
Rotating potentiometer R28 can change the blinking rate. Clockwise (CW) slows the
blinking rate and counterclockwise (CCW) increases the blinking rate. When R28 is near
the end position on CCW, both LEDs may look like they are on all the time because they
are blinking at a faster rate. The functions of D10, D11, SW2, SW3, and R28 are as follows:
Stand-alone Mode (Also referred as Manual mode):
- Green LED: Indicates the Hall sensors level, 3 hall sensors combined when the motor
rotates. If the motor shaft is rotated by hand, this LED will blink on and off.
- Red LED: In normal operation indicates the direction of rotation command. On for
forward, Off for reverse. It will blink on and off, if hardware over current fault condition
occurs (using the last downloaded parameters).
- SW2: This switch is used to toggle between Run and Stop.
- SW3: This switch is used to toggle between Forward and Reverse.
- R28: Used to control the Motor speed.
PC Mode (Also referred as GUI mode):
- Green LED: Indicates the Hall sensors level, 3 hall sensors combined when the motor
rotates. If the motor shaft is rotated by hand, this LED will blink on and off.
- Red LED: In normal operation indicates the direction of rotation command. On for
forward, Off for reverse. It will blink on and off if an over current fault condition occurs.
- SW2, SW3: They are not used in PC Mode. GUI command is used instead.
- R28: Not used with this mode.
Test Points (TP1 – TP5)
These test points are used for voltage and signal monitoring purposes.
TP1, TP2: For monitoring the +DC Bus and –DC Bus, respectively
TP3: Current Feedback signal.
TP4: +15V auxiliary power supply.
TP5: +5V auxiliary power supply.
Jumper (J2)
This is the reset jumper to the microcontroller. When shorted, it resets the microcontroller
and starts the firmware from beginning. This jumper is default to open.
Jumper (J3)
This jumper is connected across the diode of Opto-isolator, OP3. It allows the user to
externally apply an Opto-isolated PWM signal into the microcontroller for debugging
purposes.
