Please tell me that in order for the electric motor to work, do you need to constantly send a signal to the digital inputs DI4 or DI3, or is a pulse signal from the button sufficient for it to work?
Yes you can. See 4:14 onwards: Set CT ratio to 300, i.e. Current factor 30.000%. Take note that secondary wiring must be in correct phase direction. If wrong, you get negative power or wrong rotation direction.
UMC's first task is advanced motor protection based on exact current measuring. Programmable functions are an addition. A numerical relay typically won't have out-of-the-box most controller functions like DOL, REVERSE, Actuator etc function Blocks that's are 100% integrated with analogue measurements, over- under- and unbalanced load protections, restart inhibit options based on # starts/hr or heat dissipation modelling. And a lot more.
Hi Jose, in Standalone no software is needed. If you have the need for a larger installation and especcially custom logic, than the required software is availble on ABB Marketplace: Field Information Manager or FIM UMC Edition.

Hi Sir, I have CTs with ratio 300:1A, Can I use CTs for project with UMC100.3?
Yes you can. See 4:14 onwards: Set CT ratio to 300, i.e. Current factor 30.000%. Take note that secondary wiring must be in correct phase direction. If wrong, you get negative power or wrong rotation direction.
Sir what is check back settings 1.current & Simulation in Umc 100 relay.
Hi Reshav, check back is a function checking whether current is running when it's supposed to. Does that answer your question?
WHAT DIFFERENCE BETWEEN UMC 100 VS NUMERICAL RELAY

I have a problem in UMC100 ---The error appears. Error 17:application ....Anyone help me?
