P6.4 - Auto restart.
P6.4.1
b
AR wait time
ID 321
Minimum value:
1.00 s
Maximum value:
300.00 s
Default value:
1.00 s
Description:
Defines the time before the frequency converter tries to automatically restart the motor after a specific fault condition has been clear.
P6.4.2
b
AR trail time
ID 322
Minimum value:
1.00 s
Maximum value:
600.00 s
Default value:
30.00 s
Description:
Amount of time after fault set that the drive uses the restart attempts to reset the fault and restart the motor, after this time has run
out without resetting the alarm drive will fault.
P6.4.4 to P6.4.11 determine the maximum number of automatic restarts during the trial time set by P6.4.2. The time count starts from
the first auto restart. If the number of faults occurring during the trial time exceeds the values of P6.4.4 to P6.4.11, the fault state
becomes active. Otherwise the fault is cleared after the trial time has elapsed and the next fault starts the trial time count again. If a
single fault remains during the trial time, a fault state is true.
P6.4.3
b
AR start function
ID 323
Minimum value:
N.A.
Maximum value:
N.A.
Default value:
0
Options:
0 = Flying start from stop frequency;
1 = Start according to parameter stop mode; or
2 = Flying start from maximum frequency.
Description:
The start function for automatic restart is selected with this parameter. The parameter defines the start mode upon an auto restart
condition. Defines the time before the frequency converter tries to automatically restart the motor after a specific fault condition has
been clear.
P6.4.4
b
Undervoltage attempts
ID 324
Minimum value:
0
Maximum value:
10
Default value:
1
Description:
This parameter determines how many automatic restarts can be made during the trial time after an undervoltage trip.
0 = No automatic restart.
>0 = Number of automatic restarts after undervoltage fault.
The fault is reset and the drive is started automatically after the DC-link voltage has returned to the normal level.
P6.4.5
b
Overvoltage attempts
ID 325
Minimum value:
0
Maximum value:
10
Default value:
1
Description:
This parameter determines how many automatic restarts can be made during the trial time after an overvoltage trip.
0 = No automatic restart after overvoltage fault trip.
>0 = Number of automatic restarts after overvoltage fault trip.
The fault is reset and the drive is started automatically after the DC-link voltage has returned to the normal level.
