The TON_MAX_FAULT_LIMIT command sets an upper limit, in milliseconds, on how long the unit can attempt to power up the output without reaching the output undervoltage fault limit. The devices differentiate a startup UV fault and a regulation UV fault by implementing the TON_MAX_FAULT_LIMIT command. The TON_MAX_FAULT_LIMIT command can allow the devices more time than the soft-start time defined by TON_RISE to come into regulation and the UV detection is essentially delayed up to the TON_MAX_FAULT_LIMIT time. For more details, see the TON_MAX_FAULT_LIMIT (62h) section.
