■ L4-13: Door Zone Level
Sets the speed level for the car door to open. Once the car slows to the speed set in L4-13, a multi-function output terminal
set for “Door zone reached” will close (H2-†† = 52).
◆ L5: Automatic Fault Reset
After a fault has occurred, Fault Restart attempts to automatically restart the motor and continue operation instead of
stopping. The inverter can reset faults automatically. The maximum number of resets can be selected as well as the
operation mode of the fault relay.
WARNING! Sudden Movement Hazard. Do not use the fault reset function in lifting applications. Fault reset may cause the machine to
drop the load, which could result in death or serious injury.
Faults Allowing for Automatic Reset
The drive attempts to reset itself after one of the faults listed below has occurred. All other faults will need to be reset
externally.
Fault Reset Time Chart
Parameter L5-01 sets the number of times the drive can attempt to reset itself after on of the faults in the table above
occurs. The time chart below illustrates how fault reset works.

<1> The drive will accept an auto reset signal once the Up and Down commands have been removed.
<2> Software baseblock (H1-†† = 8, or 9) can also be used instead of Safe Disable inputs
Use parameter L5-06 to set up automatic fault reset.
To output a signal during fault reset, set one of the output terminals to "Reset enabled" (H2-†† = 1E).
