How do I clear error code F0022 on the vfd 440micromaster

The fault message F0022 "Hardware monitoring active" is displayed by overcurrent measured in the DC link.

detailed information you see in the Parameter List under chapter "Faults and Alarms"; Entry-ID: 23708204
Amongst other things, a short circuit of IGBT or a short circuit of chopper are possible reasons. The fault is permanent so the inverter cannot be started without the fault is occurring. In the case that the fault occurs, if all of the external cables (with the exception from the line supply voltage) are disconnected, then with a high degree of probability the drive unit is defective and must be repaired.

There are possible operating conditions at a sporadic occurring failure message F0022:

sudden load changes or mechanical obstructions
extremely short ramp-up times
poor optimization of the sensorless closed-loop vector control
incorrect braking resistor is installed with an excessively low resistance

Terminels of potenchometer

You better buy a multi turn potentiometer about 4,7 - 5,1 kOhm.

Connect its ends to "+10 V" and "ACM". The Slider connect to "AVI".

The multi turn pot can make small steps of adjustment.

Hope that it will help.

I have a 15kw motor driven off a siemens micromaster 440. I cannot get the motor to run in delta. I have to run it in star. I have similar drives on site and these motors are connected in delta. what...

Why do you want to run the motor in the delta configuration? The VFD will change the speed to anything you want to do. The delta and Wye connections are normally used to change the speed of a motor. That's what the VFD is for...??
