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 P3.16.1 (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.
