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.
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 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.
