Application Control
GPIOA13 is switched ON at the
beginning of the calculation step
and switched OFF at the end.
Period of calculation is 100 µs so the LED
D18 on the Qorivva MPC5604P controller
board shall be flashing (with period of 10
kHz) if the application runs correctly.
Functionality of GPIO12 (LED
D11 on the Qorivva MPC5604P
controller board) is as follows:
•
OFF if the application is in READY,
INIT states
•
ON if the application is in RUN, CALIB,
ALIGN states
•
Flashing if the application is in FAULT
state (flashing with period 1–2 Hz,
clearly visible by naked eye)
If no actual faults are present in
the system, all LED-like indicators
on the FreeMASTER control
page shall be dark red. If there is a
fault present, identify source of the fault
and remove it. Successful removal is
signalized by switching off the respective
LED-like indicator on the FreeMASTER
control page.
Fault condition is also signalized
by blinking LED diode D11 on
the Qorivva MPC5604P controller
board. Press UP + DOWN buttons
(SW2/SW3 on the Qorivva MPC5604P
controller board) simultaneously to clear
fault status register once in a FAULT
state. Application can be restarted by
positioning RUN/STOP switch (SW4 on
MPC5604P controller board) to RUN
position (transition from STOP to RUN in
case the switch was in RUN state when
fault event occurred).
