Hi,

I have a micro master drive which input supply 500-600V +10% -10%. I have not 500v supply at plant. Can I Use this drive on 380v input supply. How can we change P210 parameter(input supply voltage). My drive name plate is attached. or we can change some resistance in voltage sensing.

Or some thing else. 

Best Regards,

Zahid Ali Khan. 

Hello,

To change p0210 value you need to select expert parameter access level i.e. set p0003 = 3. Please refer the attached sheet which gives information about supply voltage setting. After setting this user need to carry quick/recommissioning again.

HI,

I try this but in vain. drive tripped with under voltage alarm.

Which sequence did you follwed after setting p0210?

After triggering of F0003, have you checked, p0210 & DC link voltage value?

This cannot be done.

A transformer to increase the Voltage to the operating 'window', of the drive would work, however this  would be a large transformer, and expensive. I can only suggest that you replace the drive.
