FUNCTION C
ODES
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 output (for any alarm) 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 is activated in excess of the times specified by H04, the inverter will
issue an alarm output (for any alarm) and not attempt to auto-reset the tripped state.
Listed below are the protective functions subject to auto-reset.
Protective function Alarm codes Protective function Alarm codes
Overcurrent protection OC1 , OC2 or OC3 Undervoltage LV
Overvoltage protection OV1, OV2 or OV3 Motor overheat OH4
Heat sink overheat OH1 External alarm OH2
Inverter internal overheat OH3 Motor overload OL1
Inverter overload OLU
„
Number of reset times (H04)
H04 specifies the number of reset times for the inverter to automatically attempt to escape the
tripped state. When H04 = 0, the auto-reset function will not be activated.
- Data setting range: OFF (Disable), 1 to 20 (times)
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)
- Data setting range: 0.5 to 600.0 (s)
H05 specifies the reset interval time from when the inverter enters the tripped state until it
issues the reset command to attempt to auto-reset the state. Refer to the timing scheme
diagrams below.
