Saving parameters in a non-volatile memory
The modified parameter values are stored in the volatile RAM. When the drive system is
switched off, this data is lost.
So that the changes can be restored, the data must be saved as follows in a non-volatile
manner in the Control Unit.
● Save parameters - device and drive
● Save the parameters with STARTER

NOTICE
The power supply to the Control Unit may first be switched off after saving has finished
(i.e. after saving has started, wait until it has finished and parameter p0977 has the
value 0 once more).
