Auto-Reset; Number Of Reset Times; Reset Interval - FujiFilm FVR-Micro Instruction Manual

H04,H05
Auto-reset (Times and Reset interval)
H04 and H05 specify the auto-reset function that makes the inverter automatically attempt to
reset the tripped state and restart without issuing an alarm (for any faults) even if any
protective function subject to reset is activated and the inverter enters the forced-to-stop state
(tripped state).
If the protective function works in excess of the times specified by H04, the inverter will issue
an alarm (for any faults) and not attempt to auto-reset the tripped state.
Listed below are the recoverable alarm statuses to be retried.
Alarm status
Overcurrent protection
Over voltage protection
Heat sink overheated
Braking resistor
overheated
 Number of reset times (H04)
H04 specifies the number of reset times for the inverter to automatically attempt to escape
from the tripped state. When H04 = 0, the auto-reset function will not be activated.
If the "auto-reset" function has been specified, the inverter may automatically restart and run the
motor stopped due to a trip fault, depending on the cause of the tripping.
Design the machinery so that human body and peripheral equipment safety is ensured even
when the auto-resetting succeeds.
Otherwise an accident could occur.
 Reset interval (H05)
After the reset interval specified by H05 from when the inverter enters the tripped state, it
issues a reset command to auto-reset the tripped state. Refer to the timing scheme
diagram below.

The auto-reset operation can be monitored from the external equipment by assigning the
digital output signal TRY to any of the programmable output terminals [Y1] and [30A/B/C] with
E20 or E27 (data = 26).
