A feature was added in firmware version 3.20 that flashes the enable led at a rate of 8 HZ when the drive is current foldback mode.
The Aries drive's current foldback circuit helps to protect the drive from damage due to prolonged high currents If your Drive is operating above its continuous current rating, see Figure below to predict the number of seconds until foldback will occur. For example, the figure shows that at the Aries drive's peak current rating (250% of continuous), foldback will occur after six seconds. After operating at the drive's peak current, the drive will reduce the drive current to 80% of the drive's continuous rating for 60 seconds. This is to ensure the drive's average continuous current rating is not exceeded.
