If a function factor is set, all the parameters in the above table are converted into user units.

Calculation of the minimum and maximum values of parameters “Dim factor num” and “Dim factor den”

Calculation of the minimum and maximum values of parameters “Dim factor num” and “Dim factor den”.

Limits must be included when setting the values of PAR 3900 Dim factor num and PAR 3902 Dim factor den to pre-

vent the internal variables of the drive moving out of range.

Fixed limits for each of the two parameters cannot be dened since it is the ratio between the two that must be limited

and because this limit also depends on parameter 680 Full scale speed.

There is the possibility of an overow depending on the order in which the two

parameters PAR 3900 Dim factor num and PAR 3902 Dim factor den are set and their initial value.

The conditions in which an overow could occur are described in the table below.

Initial value Values to be set Order Overflow

Den = 1 Num = 1 Den 30 – Num 10 Num – Den No

Den = 1 Num = 1 Den 30 – Num 10 Den – Num Si

Den = 30 Num = 10 Den 1 – Num 1 Num – Den Si

Den = 30 Num = 10 Den 1 – Num 1 Den – Num No

If an overow occurs when setting one of the two parameters, the other parameter is automatically set to the same

value so that the conversion value is equal to 1.

Sent via the congurator

If the parameters are sent by the GF-eXpress congurator, they are written in a set order and an intermediate overow

could occur while setting valid values.

If the value of the rst parameter sent by the congurator generates an overow, the second parameter is set to the

same value as the rst (this temporarily forces the dimension factor to 1); when the second parameter is written the

dimension factor returns to the correct value.
