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.

Changingtheendofscalespeed

When modifying PAR 680 Fullscalespeed, parameters PAR 3900 Dimfactornumand PAR 3902 Dimfactorden

are forced to 1.
