Dear Friends,
I have a Danfoss inverter drive VLT-5000, 400V 45KW at one of application where motor is only 380V 29KW. Problem is that if I set the max frequency of drive 35HZ then no problem but if I set max frequency 40HZ and run the motor, motor starts and stops well but WARN 12 (Torque Limit) warning appears again and again at LCD display.
Please assist how to control on this problem.
Anyone Familiar With Denfos Inverter?

The torque is higher than the value set in parameter 221 and 222,set these up to 160%
