MaxGrad (T/m) : Maximum allowable gradient strength MaxSlewRate (T/m/s) : Maximum allowable gradient slew rate First of all, please make sure you are using the correct number in the same unit. Check the sequence waveform to avoid waveform overlapping from multiple gradients. You might also want to check the parameters that are relevant to image resolution because they determine the gradeint amplitude. You can also first try avoiding the errors and simulate the images by using higher limits of MaxGrad...

You might want to check the sequence waveform and make sure no waveform overlap before performing simulation. Also, you might want to reduce bandwidth. Finally, you can set MaxSlewRate (in Hardware tab) to an extreme large number to ignore this warning if you are sure nothing else is wrong.

There is no limitation for the length of the RF pulse.
