Application Control
Green LED D19 (GPIO13) related
to motor 1 and the green LED
D22 (GPIO12) related to motor
2 (on the Qorivva MPC5643L controller
board) have the following functionality:
• OFF if the application is in the
READY, INIT states
• Slow flashing if the application is in
the CALIB, ALIGN states (flashing with
a period of 2 Hz)
• ON if the application is in the
RUN state
• Fast flashing if the application is in
the FAULT state (flashing with a period
of 8 Hz)
If no actual faults are present
in the system, all the LED-like
indicators on the FreeMASTER
control page will be dark red. If there is
a fault present, identify the source of the
fault and remove it. Successful removal
is noted by the switching off of the
respective LED-like indicator on the
FreeMASTER control page.
Press the UP + DOWN buttons
(SW2+SW1 on the Qorivva
MPC5643L controller board)
simultaneously to clear the fault status
register once in the FAULT state.
The application can be restarted by
positioning the RUN/STOP switch (SW3
on Qorivva MPC5643L controller board)
to the RUN position (transition from STOP
to RUN in case the switch was in the
RUN state when the fault event occurred).
If all the LED-like indicators on
the FreeMASTER control page
are off, clear pending faults by
pressing the green circled button “FAULT
CLEAR” on the FreeMASTER control
page, or alternatively by pressing the
UP+DOWN buttons (SW2+SW1 on the
Qorivva MPC5643L controller board)
simultaneously. The RUN/STOP switch
(SW3 on the Qorivva MPC5643L controller
board) must be in STOP position.
