Saving application-specific parameter values is required in the following
cases:
• after initial commissioning of the machine axis or the motor
• before replacing the controller for servicing (if possible)
Application-specific parameter values can be saved via:
• MMC → copying the parameter values by command
• "DriveTop" commissioning tool → saving the parameter values on
external data carrier
• control master → saving the parameter values on master-side data
carrier
The drive supports master-side saving of parameter values by listing
parameter identification numbers (IDNs). Using these lists guarantees
complete storage of the application-specific parameter values. It is also
possible to determine IDN lists defined by the customer.
Loading parameter values is required in the following cases:
• initial commissioning of the motor (loading basic parameter values and
motor-specific parameter values)
• serial commissioning of machine axes at series machines (loading the
values saved after initial commissioning)
• reestablishing a defined original status (repeated loading of the values
saved after initial commissioning)
• replacing the controller for servicing (loading the current parameter
values saved before servicing)
Possibilities of loading parameter values to the controller:
• motor encoder data memory → loading the parameter values by
command or via the control panel during initial motor commissioning
• MMC → loading the parameter values by command
• "DriveTop" commissioning tool → loading the parameter values from
external data carrier
• control master → loading the parameter values from master-side data
carrier
By means of checksum comparison, the control master can determine
whether the values of the application-specific parameter values currently
active in the drive correspond to the values saved on the master side.
Password
IndraDrive controllers provide the possibility to protect parameter values
against accidental or unauthorized change by means of a password. With
regard to write protection, there are 3 groups of parameters that can be
written:
• Parameters that are write-protected as a standard, such as motor
parameters, hardware code parameters, encoder parameters, error
memory etc. ("administration parameters"). The values of these
parameters guarantee correct function and performance of the drive.
• Parameters the customer can combine in groups and protect them
with a so-called customer password. This allows protecting parameter
values, that are used for adjusting the drive to the axis, after having
determined them.
• All other parameters that can be written and are not contained in the
above-mentioned groups. They are not write-protected.
