7:2.4.8 Sequence start
The sequence start function can be used for starting several motors or multiple speed mo-
tors with different parameter sets such as individual ramp times, initial voltages, current
limits etc.
Up to three individual parameter sets can be used simultaneously.
Information!
The LOCAL CONTROL menu can not be entered if Sequence start is selected.
Number of sequences (No of Seq)
To set parameters related to a sequence start, enter the Seq Start group.
Select the required number of parameter sets for the application.
The following selections are available:
No Sequence start is not activated.
The softstarter is in normal operation.
2 Two different parameter sets will be used.
3 Three different parameter sets will be used.
Press
Store
to save/activate the selected function.
First sequence setting current (1st Set Ie)
Set the current for the first parameter group and press
Store
to save the value.
This parameter will only be displayed if parameter
No of Seq
is set to 2 or 3.
Second sequence setting current (2nd Set Ie)
Set the current for the second parameter group.
Press
Store
to save the value.
This parameter will only be displayed if parameter
No of Seq
is set to 2 or 3.
Information!
If sequence start was used and the parameter No of Seq is changed to No, the overload
protection will automatically be set to Normal regardless of previous settings.
Third sequence setting current (3rd Set Ie)
Set the current for the third parameter group.
Press
Store
to save the value.
This parameter will only be displayed if parameter
No of Seq
is set to 3.
Function of first programmable input (
In0)
This parameter will automatically be set as Start2.
Function of second programmable input (In1)
This parameter will automatically be set as Start3.
Overload
The overload protection is not activated when sequence start is selected.
To activate the motor overload protection, enter this group and change to the required
function.
Information!
The overload protection should not be used when starting several motors since the total
starting time will become too long and the protection will trip.Normally the overload should
be turned off and each motor should have separate overload protection.
