reference
The frequency set at Ad. 81 (Fire mode frequency) is used for
the inverter operation in Fire mode. The Fire mode frequency
takes priority over the Jog frequency, Multi-step frequencies,
and the keypad input frequency.
When Fire mode operation is turned on, the inverter
accelerates for the time set at Dr.03 (Acc Time), and then
decelerates based on the deceleration time set at Dr.04 (Dec
Time). It stops when the Px terminal input is turned off (Fire
mode operation is turned off).
Some fault trips are ignored during Fire mode operation. The
fault trip history is saved, but trip outputs are disabled even
when they are configured at the multi-function output
terminals.
Fault trips that are ignored in Fire mode
BX, External Trip, Low Voltage Trip, Inverter Overheat,
Inverter Overload, Overload, Electrical Thermal Trip,
Input/Output Open Phase, Motor Overload, Fan Trip, No
Motor Trips, and other minor fault trips.
For the following fault trips, the inverter performs a Reset and
Restart until the trip conditions are released. The retry delay
time set at PR. 10 (Retry Delay) applies while the inverter
performs a Reset and Restart.
Fault trips that force a Reset Restart in Fire mode
Over Voltage, Over Current1(OC1), Ground Fault Trip
The inverter stops operating when the following fault trips
occur:
Fault trips that stop inverter operation in Fire mode
H/W Diag, Over Current 2 (Arm-Short)
