Set this as low as possible without getting OC faults in normal use to maximally protect your equipment. If larger than ''Medium'' setting is needed, see [[Over current fault troubleshooting]] for solution to the problem. | Set this as low as possible without getting OC faults in normal use to maximally protect your equipment.

| FFT || Goal fault filter time || Set time filter for this fault group. Defines how long drive allows exceeding these conditions before entering into fault state. || Normally values between 0-0.5 seconds are safe. Higher value may pose danger to user or equipment as motor is not being stopped soon after error condition. | | FFT || Goal fault filter time || Set time filter for this fault group.
