Dear All,

I am using MM440 drivetype no :6SE6440-2UD22-2BA1for application of trolly movement.
Drive application is for movement of trolly , i set P1300=20 (SLVC mode)
I done the quick parametrisation as per instruction in manual with P3900=1, finished & return to P3900=0.
Then i completed Motor data identification P1910=1,finished & return to P1910=0.
Then i started speed controller optimisation P1960=1, but withen 10 sec fault F0004 comes on the BOP.I checked the value of parameter r0037(In 00) -36, (In 01) -36 & other index are 20.Drive inbuilt fan working properly.

Can anyone tell me why the value in r0037 showing -36.

Fault F0004 (Inverter Over Temperarture).

Thanks in advance...

I done the quick parametrisation as per instruction in manual with P3900=1, finished & return to P3900=0.

P3900 = 1 :

When setting 1 is selected, only the parameter settings carried out via the commissioning menu "Quick commissioning", are retained; all other parameter changes, including the I/O settings, are lost. Motor calculations are also performed.

P3900 = 2 :

When setting 2 is selected, only those parameters, which depend on the parameters in the commissioning menu "Quick commissioning" (P0010 = 1) are calculated. The I/O settings are also reset to default and the motor calculations performed.

P3900 = 3 :

When setting 3 is selected, only the motor and controller calculations are performed. Exiting quick commissioning with this setting saves time (for example, if only motor rating plate data have been changed).

So if you do not like to reset the I/O setting into the factory setting, then put P3900=2.

Dear Bansal,

I done the factory setting 2 to 3 times , remove the motor connection and run the drive in v/f.same problem continue. F0004 fault with r0037 index 00 value -36.

Thanks for reply
