8.2 Basic functions
The standard drive functions include protection functions whose parameters can be set, such
as automatic limitations of current delivered based on the estimated dissipation (thermal
image or i

t drive and motor); diagnostic functions, always available to the user, who can
always check the drive status; configuration functions for some drive inputs/outputs; the
activation of parameter saving/restoring procedures, and further functions common to motion-
control equipment.
8.2.1 Saving/restoring default parameters
Upon start up, the drive loads the parameters from the memory (EEPROM) and transfers them
to the working memory (RAM).
All variations relative to parameters are carried out in the working memory (RAM).
After defining the changes/calibrations, they must be saved permanently (EEPROM) to
retrieve them upon the subsequent drive start up.
To save the parameters, use PB99.15. Saved parameters are those marked by “M” in the notes
field of the parameter tables.
To save the PLC program, use PB99.14
Sometimes, due to several changes and saves, the operating conditions may be not satisfactory
anymore. It may then be necessary to restore default parameters, that is, those defined by SBC
and residing in the system memory (EPROM), which cannot be written to. They are first
loaded to the RAM and then saved to the EEPROM
Restoring the default:
- disable the converter
- power the converter on
- the IdLE message appears on the screen
- set Pb99.7 and Pb99.13 to zero
- issue the command Pb99.12
- save the set up using commands Pb99.14 and Pb99.15.
8.2.2 Homing function
The homing function, which is available exclusively with operating modes 13, 14 or 15,
provides a typical axis reset procedure. Before using the homing function perform the
following settings:
- connect the homing sensor to digital input 3
- set the homing speed in parameter Pr4 (pay attention to the direction of rotation)
- set Pr5 = 0, b40.12=1, b40.13=0, b40.2=0.
To activate the homing procedure set b94.12=1 for a type 1 reset, or b94.13=1 for a type 2
reset. When the homing procedure is concluded the respective activation bit will be reset. If
you wish to abort the procedure, reset the command bit, stop the motor (e.g. by resetting Pr5)
and, if necessary, read b40.2 which will remain on zero.
