You may configure the drive to attempt to re-start a specified number of times after cer-
tain faults occur. Chapter 8 lists all faults and notes which ones may be reset automati-
cally.
The number of attempts at re-starting is set with parameter 608 (Restart Number). A val-
ue of 0 prevents the drive from attempting a re-start). The time duration that must elapse
between re-start attempts is set with parameter 609 (Restart Delay). The type of start to
be attempted is set with parameter 802 (Start Options); see page 83).
If the number of attempted re-starts is exceeded, the drive will trip with a fault and will
stop operating. Resetting the fault can result in instant starting. (See page 101 for more
information on faults and troubleshooting.)
Note that for 2-wire operation, the FWD or REV terminal must still be active for the drive
to attempt a re-start.
Also note that the counter for attempted re-starts will not reset to zero until ten minutes
after a successful re-start.
Two parameters in the Vacon 50X work together to configure how the motor timed over-
load operates: Parameter 510 (Rated Mtr FLA) and Parameter 610 (Timed OL Select).
Parameter 510 (Rated Mtr FLA) should be configured to the value on the nameplate of the
motor. This value is used in calculating the percentage of current at which the drive is op-
erating.
Set parameter 610 to one of the following data values to configure the desired overload
characteristic:
Options Trip Time Motor Type
Std Ind Shp 0 sec Standard Induction
Std Ind 30s 30 sec Standard Induction
Std Ind 60s 60 sec Standard Induction
Std Ind 5mn 300 sec Standard Induction
In Duty Shp 0 sec Inverter Duty
In Duty 30s 30 sec Inverter Duty
In Duty 60s 60 sec Inverter Duty
In Duty 5mn 300 sec Inverter Duty
Parameter 610 (Timed OL Select) determines the graph of Trip (Fault) Time vs. Percent
Current that is used by the Motor TOL functionality. This protective feature is speed-de-
