Is the converter operation supposed to shut down the converter if over-speed is reached? I am asking because of the free acceleration test,
“d. Free Acceleration
This test will be evaluated pass/fail. Must complete accel up to max speed and trigger
overspeed fault. No other faults maybe triggered during this event.”
The current way of dealing with overspeed is try drive the torque controller reference to 0? Is this acceptable or would you like the converter to go into protection mode and open the switches, trip the LED, ect.?
You can potentially set the torque reference to zero, but we will be evaluating how the drive is able to ensure that the speed does not exceed the maximum specification.
