57.1. Overview
The drive has four different memory zones:
• RAM
→
Volatile memory containing the drive’s current parameterization;
• Default Zone
→
Non-volatile memory that cannot be accessed by the user, containing the factory-setting of
the drive parameters.
• Work Zone
→
Non-volatile memory where customized parameters are saved. Whenever the drive is
reset, this parameterization is loaded to the RAM.
• Back–up Zone
→
Non-volatile memory storing a new drive parameterization. Back-up parameters are
modified only when the user explicitly saves the back–up zone.
Any parameter can be changed by the user. The drive will immediately use the new parameter value.
The user may save the parameter value in the Work zone. If no new value is saved for a given parameter, the drive will
use the parameter value stored in the Work zone when next turned on.
• “P” parameters can be written at any moment.
• According to factory-setting, “C” parameters may be written when the equipment is on stand-by or when the
motor is not running and the equipment is fluxing. See P003 to modify them only when the ENABLE-A and
ENABLE-B commands are deactivated (terminal MDI2 open).
• “R” parameters have the same features as “C” parameters, but the new parameter value, once written and
saved, will be used only at next power on. To use the new parameter value immediately, turn the drive off and
on or press the RESET key for at least 5 seconds.
The Work zone may be copied to the BACKUP zone through I012 included in the Eeprom menu and described in the
section below.
I012 input also allows copying the Backup zone to the WORK zone in order to restore the parameter values stored in
the WORK zone.
I012 input also allows restoring the factory-setting values for all parameters in the WORK zone.
