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.
The data must be saved in the non-volatile memory, as described below, so that the
changes are available the next time the drive is switched on.
There are various methods:
●
Save parameters using the BOP20:
press the P button on the BOP20 until the display flashes.
Flashing stops once the parameters have been saved.
●
Saving parameters with STARTER
See "Copy RAM to ROM" function
●
Saving parameters
p0977 = 1; automatically reset to 0
Note
The power supply to the Control Unit may first be switched off only after saving has
finished (i.e. after saving has started, wait until the parameter has the value 0 again).
Resetting parameters
The (loaded to the RAM) parameter values can be reset to the factory setting as follows:
p0009 = 30
Parameter reset
p0976 = 1
Start restoring all parameters to their factory settings
After this has been done, p0976 is automatically set to 0 and p0009 is set to 1.
The parameter values are reset in the volatile memory (RAM). If the reset parameter values
are also to be transferred into the ROM, then "Save parameters in a non-volatile memory"
must be executed.
Deleting all user data
User data includes:
●
Parameter values
●
Additional parameter data sets (see p0802, p0803, p0804)
