P9-32: Fire Mode input source can be set via P9-32 to an available digital input. Advanced level security (default P1-14 = 201) is
required to access menu 9 parameters
The fire mode function is enabled once an input is assigned to activate fire mode.
The logic selection for the fire mode input is configured through parameter P8-09 – Fire Mode Logic Select. It can be set to open active (0) or
close active (1). The default setting is open active such that the loss of the input signal to the digital input will cause the fire mode function to
activate.
The speed of operation of the drive whilst in fire mode is defined by parameter P8-10 – Fire Mode Speed. This can be set to any value up to
maximum speed (P1-01) in either the forward or reverse direction.
When an input is configured to trigger Fire Mode and that input is activated all other inputs to the drive are ignored. Other inputs to the drive
only become active again once the Fire Mode input is removed.
Caution: Digital input functions (including the Run / Stop and Forward / Reverse input functions) are disabled whilst fire mode is
active. The drive can only be stopped by removal of the fire mode input or by disconnection of the mains power to the drive.
The following display is used to show when the drive is operating in Fire Mode:
Trips ignored whilst drive is in Fire Mode:
Display Trip
O-t Heatsink Over-Temperature
U-t Drive Under Temperature
Th-FLt Faulty Thermistor on Heat-sink
E-trip External Trip
4-20 F 4-20mA fault
Ph-Ib Phase Imbalance
P-Loss Input Phase Loss Trip
SC-trp Comms Loss Trip
I_t-trp Accumulated overload Trip
Trips not ignored whilst drive is in Fire Mode:
Display Trip
O-Volt Over Voltage on DC Bus
U-Volt Under Voltage on DC Bus
h O-I Fast Over-current Trip
O-I Instantaneous over current on drive output
Out-F Drive output fault, Output stage trip
In order to automatically reset the drive from one of the trips that is not ignored by Fire Mode, P2-36 (Start mode select / automatic restart)
must be set to Auto-1, Auto-2, Auto-3, Auto-4, or Auto-5 depending on the number of automatic resets the user wishes to perform. Note
that there is a time delay of 20 seconds between each reset attempt.
Fire Mode operation is recorded in menu 0 for reference. Fire Mode start time is recorded to parameter P0-51 – Fire Mode Start Time. This
value is referenced to the drive life time hour’s clock so it can be seen how recent the Fire Mode operation occurred.
The period of time that the drive has operated in Fire Mode is recorded in parameter P0-52 – Fire Mode Active Minutes.
Caution: Operation in Fire Mode may affect the warranty period offered on the drive, or in some cases void the warranty provided.
Please contact your authorised distributor for more information.
One of the drive relay outputs can be set to indicate when the drive is running on fire mode. To set relay 1 to indicate fire mode operation set
parameter P2-15 = 9. To set relay 2 to indicate fire mode operation set parameter P2-18 = 9.
Quick Setup Overview:

Set Basic parameters P1-01 to P1-10.
 Set Parameter P1-14 = 201 to allow access to advanced parameters in menu 8 & 9

Set the logic required for the Fire Mode Trigger input in P8-09: 0 = Open Active, 1 = Close Active.

Set the required speed for the drive to operate at whilst in Fire Mode in parameter P8-10
Either

Set parameter P1-13 to a value that activates Fire Mode selection on digital input 2 (4, 8, or 13).
