Hello

It may be that the motor is not connected (load missing) or a phase could be missing.

Check Motor Name Plate Details Are  Parameterized Correctly

Hello Sir,

The motor is connected , and I have double checked all motor parameters are set correctly.

Please help.

Hello

If Everything Is OK 

Maybe Check Current Limit For No Load Identification 

Dear Sir,

By setting P2179=0, the drive don't showing alarm A0922 but still motor not running.

If we increase the frequency upto 24 to 25Hz then motor starts to run. can any one tell me what may be the reason?

please note that drive is 90KW Fx and we are using 22KW motor and no load connected.

waiting for reply.

Thanks

Hello 

Your Case Kinda  Strange 

Maybe Do Factory Reset Once And Try Again 

The Motor What Your Is Working With Other Drive ?..I Mean Motor Is In Good Connection?

Hello Sir,

I have tried by factory reset but the result is same.

Motor tested on other VFD, running fine.

Thanks

The current value of the motor is too low for the drive, chech the parameter r0027 on the drive and see it.

Put a load on the motor side to increase the current at the ramp up. Made the motor test P1900.

I am facing same issue but drive is 0.75kW..

A0992 displyed on drive..

Please give solution if anyone have..
