Fire Mode Activate (01.054) cannot be written directly, but it can be controlled from a digital input. This prevents fire mode from being enabled from the keypad, comms or an option module.
Fire mode is intended for purging air from a ventilation system in the event of a fire. All trips are either disabled or are automatically reset after 1s. The use of fire mode can result in damage to the drive, and so if fire mode is enabled and any trip is initiated an indication that cannot be reset by the user is stored in Potential Drive Damage Conditions (10.106). For Open-loop, RFC-A or RFC-S modes fire mode is activated and if Fire Mode Reference (01.053) has a non-zero value and Fire Mode Activate (01.054) = 1. When fire mode is activated normal drive operation is overridden as follows.
For Regen mode fire mode is activated if Fire Mode Activate (01.054) = 1. When fire mode is activated the Final drive enable is forced to be active provided the safe torque off hardware input will allow the drive to be enabled.
If the drive is in the tripped state when fire mode is activated the trip is reset and then only the trips listed in the table below can be initiated whilst fire mode is active. If any of the trips shown as resettable occur, the drive will attempt to automatically reset the trip after 1s.
