DANGER
Before using the Reset function, check whether there is any danger from the machine
or system in which the encoder is integrated!
The Reset function leads to a reset of the parameters of the position sensor object
to the factory settings, which can lead to an immediate change of the position value
output by the encoder.
This could cause an unexpected movement that could endanger people or damage the
system or other objects.
NOTE
The Reset function should only be used when the encoder is at a standstill.
Restore: Resetting to the values in the non-volatile memory
Each time the encoder is switched on, the values of the position sensor object are read
from the non-volatile memory.
b
If the parameter is to be read from the non-volatile memory during operation, then
the Restore class service (service code 15h) of the position sensor object must be
used (see table 21, page 28).
Save: Saving parameters to non-volatile memory
b
Use the Save class service (service code 16h) from the position sensor object (see
table 21, page 28).
The parameters are saved to the non-volatile memory. The following table shows
which parameters are saved.
