Issue Number: 4
5 Parameters
5.1 Overview
The Second Processor contains two parameter databases:
•
The drive database
This contains the entire drive parameter set. The Second Processor caches this
database in its own non-volatile
flash memory. At power-up the module will check to
see if this cache matches that of the drive. If it doesn’t the database will be loaded
from the drive, during which time the word “Loading” will appear for a few seconds
on the drive display. This will not occur again unless the Second Processor is
moved to a different drive with different firmware or the drive firmware is updated.
• The Second Processor database
This database contains all parameters held locally to the module such as PLC
registers as well as any other short-cut parameters (menus 90, 91, etc.)
5.2 Saving Parameters
There are different ways of saving parameters depending on the type of parameter that
needs to be saved. These are explained in detail in the following sections:
5.2.1 Saving Second Processor Parameters
The parameters that are saved to the Second Processor when performing the actions
shown below are:
•
Menus 70, 71, 74 and 75 (equivalent to P, Q, T and U register sets)
• Menu 20
To save the parameters on demand:
1. Set
Pr 81.19 to 1 (
Save Request)
2. Press the reset button
Pr 81.19 will reset to zero automatically and the module and drive will be reset.
To save the parameters on Under Voltage (UU):
•
Set Pr 81.20 to 1 (
Enable “UU trip” Save)
Note that simply performing the above operations will not save menu 20. To save menu
20 you will need to perform the above operations but ensure that
Pr 81.21 (
Enable menu
20 save and restore)
is set to 1 before doing so. This parameter does not need a module
reset for the changes to become active.
5.2.2 Restoring menu 20 parameters
To restore menu 20 parameters on power-up, Pr 81.21 (
Enable menu 20 save and restore)
needs to be at 1 at power-up therefore a drive parameter save is required. See section
5.2.3
Saving Drive Parameters .
5.2.3 Saving Drive Parameters
The parameters that are saved to the drive when performing the actions shown below
are:
•
Menus 1 thru 14, 18, 19, 21 and 22.
• Menus 15, 16 and 17, if a module is present in the relevant slot.
To save the drive parameters:
1. Set
Pr 0.00 =1000 (parameter zero in any menu when using drive keypad)
2. Set Pr 10.38 =100 (simulates pressing the reset button on the drive keypad)
