7. AUXILIARY FUNCTION
7.9 Parameter backup
POINT
When there are a lot of changing parameters of the position board and servo
amplifier and the parameter changing time effects the system startup, saving
parameters in the flash ROM of the position board by this function can
shorten the time of system startup.
(1) Flash ROM parameter backup
The contents of the parameter data area in the position board can be backed up to the flash ROM. When
executing flash ROM parameter read (system command code: 0004h) at system preparation completion
(system status code: 0001h), backup the parameter in the flash ROM with this function. Execute parameter
backup in the flash ROM in the following procedure.
Note. At factory shipment, the initial value is set to each parameter.
