4 HMI
Through the HMI it is possible to control the servo drive, view and set all of the parameters. It features a LED
display with six digits of seven segments and four keys with the increase, decrease, PROG and SHIFT functions.

4.1 KEYS
The servo drive HMI is not detachable and features four keys whose functions are described below:
PROG: Key used to change the mode of the parameters and/or validate the modified values. When the
parameters are in the search mode, pressing the P key will change them to the view or modification
mode, depending on the selected parameter. Some parameters, whose property is PP (Press P), have
their value modified only after pressing the P key.
For parameters that may be modified online, the servo drive starts using the new adjusted value
immediately and those parameters have only two modes: the search mode (which presents the letter P
and then the parameter number) and the modification mode (which presents the content of the selected
parameter, allowing the modification).
The parameters that must not be modified online can have three modes: the two mentioned above and
an intermediate one: the view mode which only displays the content of the parameter without allowing
any modification. In this case, the modified value (already in the modification mode) is only used by the
servo drive after the P key is pressed, returning to the search mode.
When the P key is pressed in the parameters that are not "Only reading", the value contained in the
parameter is automatically recorded in the non-volatile memory of the servo drive and remains recorded
until new change, except when the parameter P00664 = 0.
