Adjust Menu
This menu can be accessed when the switch is in positions and . Adjustment parameters
can be modified in stop mode OR during operation. Ensure that any changes made during
operation are not dangerous; changes should preferably be made in stop mode.
The list of adjustment parameters is made up of a fixed and a changeable part which varies according to :
-the selected macro-configuration
-the presence of an I/O extension card
-the reassignment of I/O
The following parameters can always be accessed in all the macro-configurations.
(1) In corresponds to the speed controller nominal current indicated in the catalog and on the speed controller
identification label for high torque applications.

Gain - % 0 to 100 20
Frequency loop gain : used to adapt the rapidity of the machine speed transients according to the
dynamics.
For high resistive torque, high inertia or fast cycle machines, increase the gain gradually.

DC Inj. Time - s 0 to 30 s Cont 0.5 s
DC injection braking time.
If this is increased to more than 30 s, "Cont" is displayed, permanent DC injection.
The injection becomes equal to SdC after 30 seconds.
