The current parameter set of the 931E/K servo positioning controller is saved in the RAM
(RAM = Random Access Memory). The RAM contents will get lost when the supply voltage
is switched off. For permanently saving the parameter set, use the commands File
W
Parameter set W Save parameters and copy the parameter set into the controller memory.
The contents of the controller memory will not get lost, even when the voltage is switched
off.
Every time, the servo positioning controller is reset, the contents of the FLASH will be
copied into the RAM. The reset can be activated through the following actions:
ƒ Power−off/power−on
ƒ Activation of the menu item File
W Reset Servo
ƒ Activation of the RESET button in the menu bar of the parameter setting program
Every 931E/K servo positioning controller contains a default parameter set which is firmly
implemented in the firmware and cannot be overwritten. If parameter setting is not
successful for whatever reason, the standard parameter set can be loaded and used as a
"solid basis". Select the menu items File
W Parameter set W Load default parameter set to
activate the standard parameter set. After this, the default parameter set will be copied
into the FLASH and the RAM.
10.6.2 Loading and saving of parameter sets
It is possible to save and manage parameter sets externally (e.g. on hard disk, floppy disk,
etc.). For this, the 931E/K servo positioning controller reads the parameter set and saves it
in a file or reads it from a file and saves it in the 931E/K servo positioning controller.
The PC parameter file extension is *.DCO. Select the following menu items to read and
write the *.DCO files in the parameter setting program:
ƒ File/Parameter set/File>> Servo:
Transferring the *.DCO file from the PC to the servo
ƒ File/Parameter set/Servo >> file:
Writing the *.DCO file on the PC
When writing a parameter set to a PC file, you can fill in the Motor type and Description
fields. Furthermore, you can add a comment of up to 100 lines when selecting the
Comment tab. We strongly recommend to generate descriptions to make sure that the
parameter sets will not be mixed up later. We also recommend to choose useful parameter
set names to make finding the parameter sets easier.

ƒ *.DCO files can be sent by floppy disk, CD−ROM and/or e−mail.
