Part Number:TMS320F28069
Hello,
We are having an issue with lab 12b on the high voltage TI kit. We have verified the motor parameters with labs 2a and b .
The problem is the moment we turn on the motor using lab 12b, the input voltage which is coming from a DC power supply drops from 48VDc to almost 6V. However, motor starts spinning up to 80 rpm without noise.
once we disabled force angle , the input voltage does not drop but motor starts making so much noise and does not spin smoothly. Any idea why this is happening?
