You may watch the actual current r0027 in Startdrive or STARTER. This value is transferred.

The actual current is transferred as percentage of the value stored in p2002.

 100%  of value in p2002 = 16384_dec = 04000_hex

So if the value 8192_dec is transferred, and P2002 is 2.5A then the actual current is 1.25A

That is a somewhat common problem when using standard industrial motors connected to an inverter.  Inverter duty motors have better insulation, and some even offer the option to bleed off leaking current from the shaft to protect the shaft bearings from pitting caused by that leakage current arcing across the bearings.

It is same with the r27 parameter, I am overloading the motor, it is obviously slowing down but neither speed nor motor current is changing,

But I have learned that there is a problem with the motor winding and leakage current on the motor shaft, may be that is the problem.

Note the current must be several second at the higher level, until Startdrive shows it, due to several transfer times.

I guess, in U/f mode the actualization of the motor current may be slower than in a vector control mode.
