Retry with old parameters (COM3, 9600 Baud):
To solve the access conflict with a program using the interface, close the other program
(with MS−DOS programs, also close the MS−DOS shell!!) and click Retry with old parameters
(COM3, 9600 Baud).
ƒ
Change COM port:
Click Change COM port to correct a wrong interface setting and select a different interface.
ƒ
Search Baud rates:
Under certain conditions, the servo positioning controller may use a baud rate other than
the baud rate selected in the parameterisation program. If you select Search Baud rates,
the parameterisation program will try to build up communication with different baud
rates.
ƒ
Offline parameterisation:
The Offline parameterisation is only useful, if you want to edit parameter set files without
the servo positioning controller. For more information, please see the chapter "Offline
parameterisation". (
