This
DC_Bus_OverCurrent according to fault input pin level in case of over voltage or over current in
DC-Bus line.
Name of callback function in code: pwm_Fault_A_ISR(void).
This subroutine is called at PWM A (or PWM in case of DSP56F803) Fault Interrupt.
The following analog inputs are read:
Also the detection of faults caused by Over heating and Under voltage is performed in this subroutine.
Name of callback function in code: ADC_Callback_ISR.
This subroutine is called at ADC conversion completion.
This subroutine turns on the resistive brake in DC-Bus link when actual voltage in DC-Bus u_dc_bus
is higher than BRAKE_HIGH_LIMIT.
Name of callback function in code: ADC_High_Limit_CallBack_ISR.
This subroutine turns off the resistive brake in DC-Bus link when actual voltage in DC-Bus u_dc_bus
is lower than BRAKE_LOW_LIMIT.
Name of callback function in code: ADC_Low_Limit_CallBack_ISR.
This subroutine takes care of LED handling.
Name of callback function in code: LedISR (void).
Access frequency is defined by constant TMR_1_PERIOD in definition section of program.
This subroutine takes care of Speed ramp calculation.
Name of callback function in code: RampISR (void).
Access frequency is defined by constant TMR_2_PERIOD in definition section of program.
