Fire Mode

When Fire mode is active, the drive resets all faults that occur and continues to operate at the same speed until it is
not possible. The drive ignores all commands from the keypad, fieldbuses, and the PC tool.
The Fire mode function has 2 modes, the Test mode and the Enabled mode. To make a selection of a mode, write
a password in parameter P3.17.1 (Fire Mode Password). In the Test mode, the drive does not automatically reset
the faults, and the drive stops when a fault occurs.
NOTE:
This input is normally closed.
When you activate the Fire mode function, an alarm shows on the display.

The warranty is void if the Fire mode function is activated! You can use Test mode to test the Fire mode
function and the warranty will remain valid.
