text: <s>[INST] powerFlex4 f005 error I am using a powerflex4 inverter with 0.75 kw rating 1-phase input and there is an error f005 (over voltage error) is appearing at power up and it is disappear after many tries of clearing the fault and restart it . and when I shut the power off for a time and want to run it again this fault appear again .note that : I am using it's appropriate EMC filter and input line voltage not exceeds it's recommended value (265 v) and when I measured the voltage at dc terminal it is around 308 v (normal value ) so I am kindly asking about guide to know what is the problem and what is solution ..... thanks [/INST] If this is happening at power-on, your line-in voltage is too high. It may be below the 265V max, but it needs to be closer to the nominal 240V recommended. Also, if you're cycling power, you need to give the drive bus capacitors time to discharge before applying power again. If you're cycling off-on more frequently than one minute, the bus voltage doesn't decay low enough and you end up with an F5 fault on power-up. \\n </s>
