MM440 cant save parameters

 any parameters, connected in save?

In MM440 to save parameters (i.e. RAM to EEPROM) user need to set p0971=1. After the parameters are saved/transferred, p0971 becomes 0.

P. S. - p3900 - End of quick commissioning i.e. start of motor calculation.

0 No quick commissioning (no motor calculations)

1 Motor calculation and reset of all of the other parameters, which are not included in the quick commissioning (attribute "QC" = no), to the factory setting

2 Motor calculation and reset of the I/O settings to the factory setting

3 Only motor calculation. The other parameters are not reset.

it saved I review again all parameter nothing change

but when I turn off the Micromaster it reset everything

3900 to 1 = it reset everything, motor details and fixed frequency details

3900 to 3 = it saved frequency but the motor details reset

maybe there's other parameter or maybe VFD is broken

I hope its not
