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.
Figure 5.27
Figure 5.27 Fault Reset Time Chart
<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 parameters L5-04 and 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).
n
L5-01: Number of Auto Reset Attempts
Sets the number of times that the drive may attempt to reset itself.
The drive will continuously attempt to reset. If it resets successfully, the reset counter is increased. This operation is
repeated each time a fault occurs.
When the counter reaches the number set in L5-01, the operation stops and the fault has to be reset manually after
correcting the cause.
The number of fault reset is reset to zero when:
• The drive operates normally for ten minutes following a fault reset.
• A fault is cleared manually after protective functions are triggered.
• The power supply is cycled.
n
L5-02: Fault Output Operation during Auto Reset
Determines if a fault output is triggered (H2- = E) when the drive attempts to reset.
Setting 0: No fault output
Setting 1: Fault output is set
n
L5-04: Fault Reset Interval Time
Sets a time interval that must pass before another reset attempt can be made. A setting of 0.0 disables this parameter.
n
L5-06: Undervoltage Fault Reset Selection
Determines whether a limit should be placed on the number of reset attempts after a Uv1 fault.
Setting 0: Restrict auto-reset attempts to L5-01 after Uv1
