Software Design
MOTOROLA
in
PI_CONST
timeout, there is a routine that provides over-voltage
protection during deceleration, speed ramp
(acceleration/deceleration), PI controller, V/Hz ramp and provides
parameters for PWM generation
The interrupt handlers have the following functions:
Input Capture Interrupt Handler reads the time between the two
subsequent IC edges (basic part of the Process Speed Sensor)
Fault Interrupt Handler takes care of over-current fault interrupt
(over-current part of the Process Fault Control)
PWM Interrupt Handler generates system of three-phase voltages
for the motor (Process PWM Generation)
4.4.3 READ_CONST Timeout State
This state is accessed from the main software timer in READ_CONST
rate. The following sequence is performed (see
Figure 4-5
):
All the inputs are scanned (DC-Bus voltage, speed pot, Start/Stop
switch, Forward/Reverse switch)
According to the operating mode, the speed command is
calculated
The DC-Bus voltage is compared with the over-voltage limit. Also,
over-current fault flag is checked
In case of a fault, the fault recovery routine is entered and till the
recovery time expires, the drive stays disabled
Finally, the LED driver controls individual LEDs according to the
status of the drive
