text: <s>[INST] PowerFlex 4 Max Rate of Start/Stopping I am looking at using a PowerFlex4 inverter for indexing a conveyor when reject products are presented to it. Does any one know the max rate of starting/stopping the drive per min. Many Thanks Mark [/INST] Depends what you mean by starting and stopping. If you mean adding and removing power, then I would recommend not more than once per minute. Otherwise, you will burn out the precharge resistors. If you mean starting and stopping output, then you should be able to do it as fast as the inputs will take it. The PowerFlex 4 will read the analog inputs at about 2 times per second. The digital inputs update at 2mS and have a throughput time of 6mS +/- 2mS. I hope this clarifies the situation! \\n </s>
