To run the code, complete the following steps:
- Set the AC source output to 0 V at 50/60 Hz, turn
on the AC power supply, slowly increase the input voltage from 0-V to 220-V
AC.
- Run the project by clicking the
button, or click Run → Resume in the Debug tab. Set
systemVars.flagEnableSystem to "1" after a fixed time, that means
the offsets calibration has been done and the power relay for inrush is turned
on. The motor fault flags for motorVars_M1.faultMtrUse.all need to equal
to "0" , if the values do not, check the current and voltage sensing circuit as
described in Section 3.3.4.1. - To verify current closed-loop control for motor,
set the variable motorVars_M1.flagEnableRunAndIdentify to "1" in the
Expressions window as shown in Figure 3-33. The motor needs to run with a closed-loop control using the angle from the
angle generator at a setting speed in the variable
motorVars_M1.speedRef_Hz, check the value of
motorVarsM1.speed_Hz in Expressions window, both variables value need
to be very close.
- The motor current Iq can be set and changed with
motorVars_M1.Idq_Set_A.value[1]
- Connect oscilloscope probes to IPM output to watch the motor phase voltage and current as shown
in Figure 3-34. Change the Idq_set_A[0].value[1] in the Expressions window,
the motor phase current needs to be increasing accordingly.
- If the motor cannot run with current-closed loop
and appears to experience an overcurrent fault, check if the sign of
adcData[0].current_sf and the value of
userParams[0].current_sf are set correctly according to the hardware
board.
- The controller can now be halted before setting
the motorVars_M1.flagEnableRunAndIdentify to "0", and the debug
connection terminated. Fully halting the controller by first clicking the
Halt button
on the toolbar or by clicking Target →
Halt. Finally, reset the controller by clicking on
or
clicking Run → Reset. - Close CCS debug session by clicking on
Terminate Debug Session
or clicking Run → Terminate.
