F0003 = Fault - UnderVoltage
A0503 = Warning – UnderVoltage
r0026 = Displays DC-link voltage, is showing 0vdc(?)
- where do you measure the 685V DC?

r1242 CO: Switch-on level of Vdc-max
p0210 = Supply voltage; is set to 400V(?)
400V AC ~ 570VDC
600V AC ~ 850VDC
685V DC ~ 480VAC!
what inverter do you have? 400V/ 600V?

Good Morning. I have a problem in the micromaster 440 and the voltage of the dc link is 550vdc but in parameter r026 I only have 140v, where is the voltage of parameter r026 detected and what can be the cause and how can it be solved? thank you
