NOTE!
When activating the "Fire Mode" function, the user acknowledges that the protection functions of the
CFW300 are disabled, which may result in damages to the CFW300, to the components connected
to it, to the environment in which it is installed and to the people present in such environment.
Therefore, the user takes full liability for the resulting risks. The operation of the inverter with the “Fire
Mode” function enabled voids the warranty of the product. The operation under such condition is
internally registered by the CFW300 and must be validated by an engineer and occupational safety
professional duly qualified.
If the user presses the P key, the message will disappear from the display (A211), but the operation
mode will continue to be shown in parameter P0006. It is also possible to indicate this condition in
a digital output (DOx) previously programmed for “Fire Mode”. During the operation in “Fire Mode”,
all the stop commands are ignored (even General Enable).
Some Faults (considered critical) that may damage the CFW300 will not be disabled, but they can
be infinitely reset automatically (define this condition in parameter P582): Overvoltage on the DC Link
(F022), Overcurrent/Short Circuit (F070).
P580 – Configuration “Fire Mode”
Adjustable
Range:
0 = Disabled
1 = Enabled (keeps speed reference)
2 = Enabled (set speed reference to maximum [P0134])
3 = Reserved
4 = Enabled (general disable, motor will coast to stop)
Factory
Setting:
0
Properties: cfg
Description:
This parameter defines how the Fire Mode functionality will work in the CFW501 frequency inverter.
Table 11.2: Options for the parameter P580
P580 Description
0 Fire Mode function is inactive
1
Fire Mode function is active. When the DIx set to Fire Mode is opened, “A211” will be shown on the HMI and no changes
will be made to the Speed Reference or to the inverter control
2
Fire Mode function is active. When the DIx set to Fire Mode is opened, “A211” will be shown on the HMI and the Speed
Reference will be set automatically to maximum (P134) value. The motor will accelerate to this new reference
3 Reserved
4
Fire Mode function is active. When the DIx set to Fire Mode is opened, “A211” will be shown on the HMI and the pulses in
the output will be disabled. Motor will coast to stop
P582 – Fire Mode Auto-reset Adjustable
Adjustable
Range:
0 = Limited
1 = Unlimited
Factory
Setting:
0
Properties: cfg
Description:
This parameter defines how the auto-reset functionality will work in Fire Mode when a critical fault occur (DC
Link Overvoltage (F022) and Overcurrent/Short-circuit (F070)).
Table 11.3: Options for the parameter P582
P582 Description
0 Limited. Auto-reset works as defined in P340 parameter
1 Unlimited. The auto-reset happens after 1s of a critical failure detection regardless of the value set in P340
